FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with gingivitis is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about gingivitis, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to gingivitis, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on gingivitis. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to gingivitis, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on gingivitis. The Editors

CHAPTER 1. STUDIES ON GINGIVITIS Overview In this chapter, we will show you how to locate peer-reviewed references and studies on gingivitis.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and gingivitis, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “gingivitis” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Influence of Toothbrush Wear on the Variables of Plaque and Gingivitis in Clinical Trials Source: Journal of Dental Hygiene. 75(2): 150-155. Spring 2001. Contact: Available from American Dental Hygienists' Association. 444 North Michigan Avenue, Chicago, IL 60611. (312) 440-8900. Website: www.adha.org. Summary: Although toothbrush wear has been shown not to be critical in ensuring optimal plaque removal, the degree of toothbrush wear occurring in a clinical trial may influence the results of the trial. This article reports on a study undertaken to determine the effects of toothbrush wear on the clinical variables of dental plaque and gingivitis (inflamed gums). There were 107 subjects who participated in the six month clinical trial in which plaque and gingivitis scores were assessed in relation to toothbrush wear at 2,

Gingivitis
4, 12, and 24 weekly intervals. At each appointment, the toothbrushes being used were assessed for wear and replaced if necessary. The researchers found that 58 percent of the group were 'rapid' and 42 percent were 'slow' wearers. Of the group, 18.6 percent required replacement toothbrushes within two weeks from baseline with 50.9 percent of replacement toothbrushes being issued within four weeks of the start of the trial. Two subjects required as many as 10 replacement toothbrushes over the six month trial period. 'Slow' wearers had significantly lower plaque scores than 'rapid' wearers at weeks 4 and 12, whereas the 'rapid' wearers had significantly lower gingivitis scores than 'slow' wearers at weeks 2 and 4. The author concludes that significant toothbrush wear patterns of people participating in clinical trials should be taken into account when designing clinical trials assessing plaque and gingivitis scores. It may be necessary to exclude 'rapid' toothbrush wearers from clinical trials that assess plaque and its removal. In addition, as the rate of toothbrush wear varied considerably among subjects, the simple classification of subjects into 'rapid' and 'slow' wearers may require further subgrouping. 4 tables. 11 references. •
Painful Gingivitis May Be an Early Sign of Infection with the Human Immunodeficiency Virus Source: Clinical Infectious Diseases. 16(3): 233-236. February 1993. Summary: Anecdotal reports have suggested that painful gingivitis may be associated with infection due to the human immunodeficiency virus (HIV). This article reports on a study of 20 patients who came to the emergency room and complained about gum pain. They were then evaluated for HIV infection. Seven of the 20 patients (35 percent) were seropositive for HIV. Three of the seven HIV-seropositive patients were unaware of their HIV infection until tested in this study. Regardless of HIV serological status, all patients demonstrated a severely depressed mitogenic response when compared with control subjects. The authors conclude that identification of clinical presentations that reflect an early stage of HIV infection such as painful gingivitis, could aid in the timing of therapy and prevention of the spread of HIV infection. 1 table. 19 references.

Journal Fulfillment Services Department, P.O. Box 2485, Secaucus, NJ 07096-2485. Fax (202) 348-4505. Summary: High intraoral load of the bacterium Actinobacillus actinomycetemcomitans in subjects with no or minimal periodontal disease may induce subtle changes in clinical periodontal conditions. This article reports on a study undertaken to compare, at a site level, the clinical conditions in two groups of young adults with plaque-induced gingivitis. In one group, more than 20 percent of subgingival (under the gums) sites harbored cultivable A. actinomycetemcomitans (n = 9), whereas in the other group, the organism was present I n20 percent of fewer subgingival plaque samples (n = 8). Whereas no overt differences in clinical conditions could be ascertained, on average, the association between the presence of subgingival plaque and bleeding upon probing was considerably stronger in subjects with only a few subgingival sites harboring A. actinomycetemcomitans, as compared to subjects with a widespread intraoral distribution of the organism. Since the proportion of sites not bleeding upon probing in the presence of supragingival plaque was slightly elevated in these subjects, the present findings may suggest a suppressed inflammatory reaction on supragingival plaque in

Gingivitis in the Genesis of Heart Attack and Other Arteriosclerotic Diseases Source: Dentistry Today. 20(11): 94-95. November 2001. Contact: Available from Dentistry Today Inc. 26 Park Street, Montclair, NJ 07042. (973) 783-3935. Summary: New evidence of microbial aggravation and its mechanisms in coronary artery disease (CAD) and other atherosclerotic (hardening of the arteries) disorders was presented during the 50th annual session of the American College of Cardiology, held in Orlando, Florida in 2001. This article reviews the role of gingivitis in the genesis of heart attack and other arteriosclerotic diseases, reporting on data from the conference and other major recent conferences and publications. The author notes that few patients recognize how much infection and inflammation are present in their mouths. Their risks should be identified for them by a dentist. The author also reports that prior to this new information, attention was mainly directed to the progression of the arterial damage; now, increasing attention is directed to mechanisms for regression, or improvement in the vascular status. Dentists, physicians, and patients can all benefit from adequate evaluation of periodontal disease, and adequate professional communication among themselves.

Gingivitis: A Prelude to Periodontitis? Source: Journal of Clinical Dentistry. 6(Special Issue): 41-45. 1995. Summary: This article explores the role of gingivitis in the progression of periodontitis. Topics covered include therapeutic intervention in gingival disease, the progression from gingival health to gingival disease, age-related gingival microbiology, predictive patterns of destructive periodontal disease, the host response to pathogenic bacteria, predicting disease progression, the management of gingival health, and the benefits of stannous fluoride. The author concludes that the reduction of gingivitis in the general population results in more than merely cosmetic improvement following the reduction of gingival bleeding and some forms of halitosis. There is overwhelming evidence that gingivitis is linked to periodontitis and that the elimination of gingivitis will result in the reduction of attachment loss in the majority of the population. 59 references.

Summary: This article reports on a project that created a mechanism to identify adolescents with marked gingival (gum) disease with a visual screening instrument that can be administered by a school nurse or health care worker. School-based interventions are effective in oral health promotion, so the intervention strategy focused on identification of the health problem; referral for diagnosis, treatment, and follow up; education and counseling about risk behaviors and impediments to access to care; and evaluation of the intervention methods. The examinations were conducted in a mobile dental van at a middle school located in a predominantly Hispanic and dentally underserved community in the greater San Antonio area. The study addressed three

issues: agreement of the nurse and dentist in the outcome of the visual examination; effectiveness of the screening tool in detecting marked gingival disease; and effectiveness of the screening process determined by referral for treatment. The study showed that this screening tool provides the school nurse with defined criteria to identify students with severe gingival inflammation. 2 tables. •
Postscaling Bacteremia in HIV-Associated Gingivitis and Periodontitis Source: Oral Surgery, Oral Medicine, Oral Pathology. 73(5): 550-554. May 1992. Summary: This article reports on a study that assessed the incidence of postscaling bacteremias in patients seropositive for HIV who have unequivocal evidence of periodontal infection. In addition, the authors tried to ascertain whether the posttreatment febrile episode reported by HIV-positive patients is a predictable sequela to the temporary presence of microorganisms in the peripheral circulation. Aseptive venipuncture was used to obtain samples of blood from 22 HIV-positive patients with gingivitis (HIV-G) and 19 HIV-positive patients with periodontitis (HIV-P), 15 and 30 minutes after the initiation of routine dental scaling and root planing. Six of the samples from HIV-G subjects were positive for colony-forming units 15 minutes after scaling but not at 30 minutes. Similar evidence of bacteremia was found in seven of the HIV-P patients 15 minutes after scaling, with no microbial growth detectable in samples obtained at 30 minutes. In two HIV-G and three HIV-P patients with demonstrable bacteremias a postoperative fever developed. For both HIV-G and HIV-P groups, no significant difference was found between the absolute CD4 T-cell counts of nonbacteremic versus bacteremic patients. The authors conclude that special provisions for antibiotic prophylaxis in this patient group may be unnecessary. 3 tables. 12 references. (AA-M).

Comparison of the Efficacy of a Novel Electric Toothbrush and a Manual Toothbrush in the Treatment of Gingivitis Source: American Journal of Dentistry. 11(Special Issue): S23-S28. September 1998. Contact: Available from American Journal of Dentistry. Subscription Department, 9859 IH-10 West, Suite 107/489, San Antonio, TX 78230-2236. Summary: This article reports on a study undertaken to compare the efficiency of a new electric toothbrush featuring a novel three dimensional brush head action, with a manual toothbrush, in resolving gingivitis which had been allowed to develop in a group of subjects prior to the treatment phase of the study. This randomized split mouth study includes a total of 35 healthy non dental students who refrained from any oral hygiene on the lower jaw for a period of 21 days in order to develop gingivitis (inflamed gums). They then brushed one quadrant of the lower jaw with the Braun Oral B 3D Plaque Remover and the other with a manual toothbrush for a period of 4 weeks. Plaque and gingivitis were evaluated at the start of the study, after the 21 days of no oral hygiene, and after 1, 2, 3, and 4 weeks of brushing twice a day. At the end of the study, the 3D was found to be significantly more effective at reducing bleeding on probing for all sites combined and all individual sites. Plaque removal was also significantly more effective with the 3D. Subjects in the study reported that they preferred the 3D to the manual toothbrush and said that it would encourage them to brush for longer. The authors conclude that the new Braun Oral B 3D Plaque Remover offers advantages over a manual toothbrush in terms of plaque control and improvement of gingival condition. 3 figure. 2 tables. 18 references.

Impact of the Sonicare Toothbrush on Plaque and Gingivitis Source: Compendium of Continuing Education in Dentistry. 23(7): 7-10. July 2002. Contact: Available from Dental Learning Systems. 241 Forsgate Drive, Jamesburg, NJ 08831. (800) 926-7636. Website: www.dentallearning.com. Summary: This article reviews both in vivo and in vitro studies that illustrate the effectiveness of the sonicare toothbrush in improving oral health. The sonicare toothbrush has been shown to be 40 percent more effective in removing plaque than a manual toothbrush, 82 percent better in removing plaque from interproximal areas, and to reverse gingivitis (inflamed gums). In vitro studies have examined the ability of the sonicare toothbrush to remove plaque bacteria beyond the reach of the bristles. The sonicare toothbrush has also been shown to produce significantly less dentin wear in vitro than another leading power toothbrush. 6 figures. 12 references.

Review of Efficacy Studies of an Antiplaque-Antigingivitis Essential-Oil-Containing Dentifrice Source: Journal of Practical Hygiene. 10(2): 29-33. March-April 2001. Contact: Available from Montage Media Corporation. 1000 Wyckoff Avenue, Mahwah, NJ 07430-3164. (201) 891-3200. Summary: This article reviews the efficacy studies that investigated an antiplaque antigingivitis dentifrice (a mouthrinse) that contained essential oils. The effectiveness of a new essential oil containing (EOC) dentifrice in the control of plaque and gingivitis (gum infection) was initially evaluated in multiple short term human studies and later confirmed in a definitive six month clinical trial conducted according to guidelines established by the American Dental Association (ADA). The addition of zinc salts provided desired anticalculus benefits as demonstrated in two long term human clinical studies, while the bactericidal, anticaries, and stain reduction properties were verified utilizing accepted scientific testing methods. The authors conclude that the research demonstrates that a dentifrice containing a fixed combination of essential oils is effective against dental plaque and gingivitis and is consistent with the body of published long term clinical trials on essential oil mouthrinses (Listerine). The authors briefly discuss the use of these dentifrices in a program of oral hygiene. Increasing confidence in the value of dentifrices containing chemotherapeutic agents has resulted in their expanded use by people affected by gingivitis and acceptance by the professional dental community. 1 figure. 3 tables. 22 references.

Role of Pharmacotherapeutics in the Reduction of Plaque and Gingivitis Source: Journal of Practical Hygiene. 9(6): 46-50. November-December 2000. Contact: Available from Montage Media Corporation. 1000 Wyckoff Avenue, Mahwah, NJ 07430-3164. (201) 891-3200. Summary: This article reviews the role of pharmacotherapeutics in the reduction of dental plaque and gingivitis (gum infection). The author notes that while mechanical aids (e.g., toothbrushes, floss, and interdental devices) are widely used to achieve proper oral hygiene, they occasionally fail to meet this goal and to reduce the bacteria below the patient's threshold for disease. In these patients, drug therapy may be indicated. The author discusses selection, research, and delivery considerations; and specific drugs including phenolic related essential oils, triclosan, bisbiguanides (including chlorhexidine), quaternary ammonium compounds, herbal extracts, and
8
Gingivitis
oxygenating agents. The author concludes that the ineffectiveness of mechanical plaque control is based largely on the fact that people do not brush or floss effectively or regularly. Several antimicrobial products have demonstrated safety and range of efficacy. Recommendations should be based on level of infection, research, expected outcomes, and patient input. Mouthrinses should be used as adjuncts and not replacements for traditional plaque control. 2 tables. 60 references. •
Treatment of Plaque-Induced Gingivitis, Chronic Periodontitis, and Other Clinical Conditions Source: Journal of Periodontology. 72(12): 1790-1800. December 2001. Contact: Available from American Academy of Periodontology. Suite 800, 737 North Michigan Avenue, Chicago, IL 60611-2690. (312) 573-3220. Fax (312) 573-3225. Summary: This article was prepared by the Research, Science and Therapy Committee of the American Academy of Periodontology and is intended for the information of the dental profession. The article represents the position of the American Academy of Periodontology regarding the current state of knowledge about treatment of plaqueinduced gingivitis (inflamed gums), chronic periodontitis, and some other clinical conditions. Therapy for individuals with chronic gingivitis is initially directed at reduction of oral bacteria and associated calcified and noncalcified deposits. Necrotizing ulcerative gingivitis (NUG) usually responds rapidly to the reduction of oral bacteria by a combination of personal plaque control and professional debridement (scaling). Appropriate therapy for patients with periodontitis varies considerably with the extent and pattern of attachment loss, local anatomical variations, type of periodontal disease, and therapeutic objectives. The introduction notes that there are some situations where the described therapies will not resolve disease or arrest disease progression. Furthermore, the treatments discussed should not be deemed inclusive of all possible therapies, or exclusive of methods of care reasonably directed at obtaining good results. 162 references.
Federally Funded Research on Gingivitis The U.S. Government supports a variety of research studies relating to gingivitis. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to gingivitis. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore gingivitis. The following is typical of the type of information found when searching the CRISP database for gingivitis: 2

Project Title: BIOFILM FORMATION AND METABOLISM ON DENTAL SURFACES Principal Investigator & Institution: Ferretti, Joseph J.; Senior Vice President & Provost; Microbiology and Immunology; University of Oklahoma Hlth Sciences Ctr Health Sciences Center Oklahoma City, Ok 73126 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 30-JUN-2008 Summary: (provided by applicant): The present Center of Biomedical Research Excellence (COBRE) proposal is designed to grow oral health related research, and increase the competitiveness of investigators associated with the University of Oklahoma College of Dentistry and affiliated institutions with common interests in dental research. At the center of this proposal are the junior investigators who will take a multidisciplinary approach to study microbial biofilm formation and metabolism on natural and artificial dental surfaces. The establishment and evolution of microbial biofilms on smooth surfaces in the oral cavity leads to dental caries, gingivitis, and periodontitis, accounting for the majority of all dental disease. To approach this problem from a number of vantage points, project investigators in the present proposal were drawn from complementary fields, including microbiology and genetics, pathology and cell biology, periodontics, and dental materials. An administrative core will oversee and work with the junior investigators, providing mentoring from senior investigators, enhanced core facilities, and an external advisory committee of internationally recognized scientists in the thematic topic of microbial biofilms on dental surfaces. In addition, a training program for students at all levels will be initiated as well as an outreach program to identify faculty and students at other institutions in the state interested in dental biofilm research. The university administration has committed to expand this effort with the addition of two permanent faculty positions from institutional resources. This COBRE proposal provides the necessary resources, infrastructure, and mentoring required for Oklahoma dental researchers to be successful in competing for future NIH funding as independent investigators. The ultimate benefit of this program will be the translation of research knowledge to treatment and prevention of oral diseases. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: BONE MINERAL DENSITY AS A PREDICTOR OF PERIODONTITIS Principal Investigator & Institution: Wactawski-Wende, Jean; Assistant Professor; Social and Preventive Medicine; State University of New York at Buffalo Suite 211 Ub Commons Amherst, Ny 14228 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2006 Summary: (provided by applicant): The overall purpose of this study is to determine the role of oral and systemic bone mineral density (BMD) in the development of new and progressive periodontal disease in postmenopausal women. We hypothesize that low BMD will be associated with both new and progressive periodontitis over time by

increasing susceptibility to destructive periodontitis. We propose a longitudinal assessment of BMD and its role in establishment of periodontal disease in postmenopausal women with systematic studies using sensitive and accurate measures of skeletal and oral BMD, and periodontal disease. As part of the BMD assessment, we will further validate the methodology for oral BMD. In concert with these, assessment of a variety of potential co-risk factors for both low BMD and periodontitis will allow us to determine their contribution to this association. The systemic covariates include age, body mass index, smoking, alcohol, hormone use, socioeconomic and psychosocial factors, medications, medical and reproductive history, and diet. Local covariates include plaque, gingivitis, probing depth, previous dental care, and dental care habits. Study subjects will be recruited from an established cohort of postmenopausal women with baseline assessments of BMD and periodontitis as part of an ongoing crosssectional study. We propose a 3-vear follow-up examination in 1000 postmenopausal women already enrolled in the NIH Women's Health Initiative study. To date, studies have not characterized the specific role of BMD either skeletal or mandibular on periodontal disease incidence and progression in a large cohort of postmenopausal women. Our preliminary cross-sectional studies have determined that skeletal BMD is associated with alveolar crestal height, tooth loss and clinical attachment loss. The proposed longitudinal study will have sufficient sample size and statistical power to assess the temporal relationship between BMD and periodontitis and the effects of a large set of co-risk factors and potential confounding factors affecting osteopenia, periodontal disease or both. This study provides a unique opportunity to define this relationship in a cost effective manner in a cohort of postmenopausal women under study as part of the Women's Health Initiative and has great practical significance. Low BMD is likely of considerable importance in the onset and progression of periodontitis. Hence once the relationship is established, modalities effective in the prevention and treatment of osteoporosis may prove useful for prevention and treatment of periodontitis and subsequent tooth loss.

Project Title: CULTIVABLE & UNCULTIVABLE PERIODONTAL SPIROCHETES Principal Investigator & Institution: Dewhirst, Floyd E.; Senior Member of Staff; Forsyth Institute Boston, Ma 02115 Timing: Fiscal Year 2001; Project Start 01-AUG-1992; Project End 30-JUN-2004 Summary: The long-term goal of the proposed research is to determine the role of spirochetes in the etiology of oral infectious diseases and to develop means to prevent or control spirochete infections. There is substantial evidence implicating spirochetes, particularly T denticola, as etiologic agents in periodontal diseases. In acute necrotizing ulcerative gingivitis (ANUG) and some forms of periodontal disease, spirochetes may comprise over 50 percent of the bacterial flora. Previously in this grant, we have helped to expand the number of known cultivated treponemes from 4 to 10 species, and

11
identified an additional 47 currently uncultivable Treponema species. We have developed 16S rRNA based DNA probes that allow identification of cultivable and uncultivable treponemes in clinical samples. Aim 1 of this proposal will determine which spirochetes are associated with a variety of oral infectious diseases, and how treponemes other than T. denticola relate to Socransky's previously described periodontal bacterial complexes. Determining associated pathogens is a requisite first step in any study of infectious disease. Aim 2 will obtain a molecular understanding of msp, a major surface antigen of T. denticola. We will determine the diversity of msp genotypes in individuals and how msp genotypes shift over time in bacterial populations. Preventive measures, such as vaccines, require an understanding of the diversity of epitopes of the major antigens and how expression of antigen diversity varies over time. Aim 3 of this proposal will obtain information on the genome size and degree of host association as reflected by genome size reduction for each of the known cultivable oral treponemes. The final Aim will examine the genomic repertoire of T. maltophilum, a second oral treponeme implicated in oral infections. This genome survey will provide insight into the metabolic and pathogenic capabilities of the organism and will identify targets for vaccines or drug treatment. This research will improve our understanding of a major segment of the oral bacteria and will provide information necessary for the eventual control and prevention of oral infectious diseases such as periodontitis, pericoronitis, ANUG, noma, and Ludwig's angina.

Project Title: DENDRITIC CELLS IN PERIODONTAL HEALTH AND DISEASE Principal Investigator & Institution: Oringer, Richard J.; Periodontics; State University New York Stony Brook Stony Brook, Ny 11794 Timing: Fiscal Year 2003; Project Start 05-AUG-2003; Project End 30-APR-2008 Summary: (provided by applicant): This proposal for a mentored patient-oriented research career development award will provide the candidate the knowledge and skills required to design, conduct, and analyze clinical research projects. The educational, clinical, and research resources at Stony Brook University's School of Dental Medicine, School of Medicine (SOM), School of Health Technology and Management (SHTM), and General Clinical Research Center (GCRC) will provide the candidate a robust environment for career development. A systematic plan has been developed that incorporates didactic courses provided by the GCRC, SHTM, and SOM with supervised research that includes clinical studies and complimentary laboratory analysis. The acquisition of both basic and applied research skills is essential for the candidate to transition into an independent investigator who can interface with basic scientists to design studies that evaluate novel hypotheses and ultimately translate this information into new diagnostic and therapeutic modalities. The research plan includes human studies to address a novel hypothesis regarding the role of dendritic cells (DC) in the pathogenesis of gingivitis and chronic periodontitis (CP). The hypothesis is that species in the plaque biofilm such as Porphyromonas gingivalis may promote the development of organized lymphoid aggregates in the lamina propria around the dentition, described as oral lymphoid follicles (OLF). Preliminary data indicate that Langerhans Cells (LC), mature dendritic cells, and T cells are the principal cellular components of the OLF. Furthermore, the transition from periodontal health to gingivitis to CP involves different stages in the development of OLF, as initiated by the plaque biofilm, propagated by cytokine/chemokine milieu, and induced by LCs. The specific aims of this proposal will use 2 longitudinal studies to establish the changes that occur in DCs and their trafficking molecules during 1) experimental gingivitis (EG) and 2) CP. In Aim
12
Gingivitis
1, periodontally healthy subjects will be restored to gingival health following the EG protocol, and in Aim 2, CP subjects will receive conventional treatment and then be enrolled in a maintenance program. The information generated in this training program will further elucidate the role of the host response in periodontal diseases and potentially lead to the development of therapies aimed at prevention and treatment of these conditions.

Project Title: DIAGNOSTIC OPITCAL IMAGING OF PERIODONTAL TISSUES Principal Investigator & Institution: Otis, Linda L.; Associate Professor and Director; Oral Medicine; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2001; Project Start 30-SEP-1994; Project End 31-JUL-2003 Summary: (Adapted from Applicant's Abstract): Optical Coherence Tomography (OCT) is a non-invasive optical technique for cross-sectional imaging of biologic tissues which permits identification of both internal structure and surface contour of hard and soft tissues without ionizing radiation. Based on previously sponsored efforts, the authors have designed and constructed an OCT instrument for imaging teeth and periodontal tissues. Initial human studies demonstrate the feasibility of this method. The goal of this proposal is to construct a small, compact clinical instrument that will allow access to all tooth-bearing regions within the oral cavity. The capacity of OCT to characterize morphology, localize structures and quantify sub-gingival calculus will be determined in a small patient study. The authors hope to identify OCT signals associated with periodontitis and/or gingivitis. In order to make the device clinically relevant., the authors propose to optimize the instrument and evaluate its performance in comparison to standard techniques. The specific aims of the proposal are to (1) construct an improved, miniaturized intraoral OCT imaging hand piece; (2) miniaturize OCT imaging system components; (3) image and characterize healthy and diseased periodontal tissue and optimize OCT imaging parameters; (4) compare OCT imaging to standard assessment methods; and (5) investigate the potential of OCT to quantify gingival inflammation. Images produced to date suggest that OCT may delineate pathological changes in gingival fiber groups based on changes in optical properties. Finally operating OCT systems at multiple wavelengths may be used for quantification of blood and fluid content in tissue. This project is carried out in conjunction with Lawrence Livermore National Laboratory. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: EFFICACY OF TAILORED ORAL HEALTH EDUCATION Principal Investigator & Institution: Pallonen, Unto E.; Associate Research Scientist; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-JUL-2008 Summary: (Provided by the applicant): The long-term objective of this project is to develop an effective tailored behavior change expert system (ES) education program to promote and maintain good oral health and prevent oral diseases among low-income children and their caregivers. To achieve this, the proposed multimedia-based, self-help intervention is designed to be easy to use and easy to diffuse for large-scale use through personal computers. Due to the current lack of tailored self-help behavior change dental interventions, substantial time and resources are needed to develop the content and to test the instruments and feasibility of the proposed interventions. This project has five

13
specific aims: 1) To design and produced two interventions to promote oral health and prevent oral disease among caregivers and their children: (i) an interactive, tailored, theory-driven, behavior change ES education program, and (ii) an untailored health information HI comparison program. 2) To assess the feasibility and usability of these unique interventions with a small-scale feasibility study prior to their final implementation. 3) To revise the interventions based on the findings of the feasibility study and implement the efficacy trial. 4) To evaluate the efficacy of the interventions with two clinical outcomes: gingivitis among caregivers and untreated tooth decay among caregivers and their children. 5) To examine the extent to which the clinical outcomes are mediated by the affective, evaluative, and situational individual factors influenced by the tailored intervention, or by broader psychosocial factors addressed in other center projects. The efficacy of the tailored ES intervention, whether it results in better oral health than the untailored HI intervention, will be tested by the randomized controlled trial. In year 4 of the course of the longitudinal center research, the participating caregivers, low income African Americans recruited from the poorest 39 census tracks in the city of Detroit, will be randomly assigned to one of the two education programs at the beginning of the multimedia intervention session. The oral follow-up examination at year four will be the baseline measurement of this trial, and changes in the outcomes will be assessed in the follow-up examination in year 6. Both the participants and examiners will be blinded from the intervention regimens. Production and evaluation of a state of the science, interactive, tailored multimedia selfhelp ES program for oral health will provide an opportunity to obtain currently nonexistent information about the ability to influence behaviors that determine oral health status among low SES African Americans caregivers and their children.

Project Title: INITITATION OF BIOFILM FORMATION IN STREPTOCOCCUS GORDONII Principal Investigator & Institution: Gilmore, Keeta S.; Associate Research Professor; University of Oklahoma Hlth Sciences Ctr Health Sciences Center Oklahoma City, Ok 73126 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 30-JUN-2008 Summary: Biofilms are central to oral ecology in health and disease. Historically, bacteria have been viewed as single-celled entities, but it is now clear that bacteria exist in stable communities that form specific and highly optimized architectures. The central hypothesis of this proposal is that the structures of these biofilms, as well as their persistence, requires a delicately orchestrated developmental program and communications network, characteristics traditionally reserved for the behavior of multicellular organisms. Just as tissue development requires the orchestrated and sequential nurturing of select cells and culling of others, the central hypothesis of this proposal predicts an analogous process that results in the outgrowth of bacterial cells in some areas of a colonized surface, and the culling of cells in others. The net affect of orchestrated cell growth and cell elimination is the production of a specifically designed biofilm architecture that optimizes nutrient access, waste elimination, protection from environmental hazards, and collectively, the ability to persist. An innovative aspect of this hypothesis is that the model predicts the existence of a "programmed cell death" pathway, as well as a specific, phase-varied antidote or neutralization pathway, both of which being critical for controlled development of the optimized biofilm architecture. The overarching goal of this research is to develop a rational basis for the design of new therapeutics to treat biota shift diseases of the oral cavity, such as gingivitis and
14
Gingivitis
periodontitis, while nurturing the formation or restoration of healthy oral flora. Streptococcus gordonii, an organism that is one of the first to colonize the tooth surface, and hence occurs at the base of the dental plaque consortium, will be the model organism of study.

Project Title: LYSIS OF CARIOGENIC BACTERIA BY PHAGE-ENCODED ENZYMES Principal Investigator & Institution: Delisle, Allan L.; Oral & Craniofacial Biol Scis; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2001; Project Start 15-SEP-2000; Project End 31-AUG-2003 Summary: The long-range, health-related goal of this proposal is to develop speciesspecific, cell wall-hydrolyzing enzymes encoded in the genomes of phages specific for Streptococcus mutans and Actinomyces naeslundii as new therapeutic treatments for dental caries. S. mutans is the primary etiological agent of human enamel caries, whereas A. naeslundii (A. viscosus), an early colonizer of dental plaque, has long been believed to be involved in gingivitis and root surface (cementum) caries. The major objective of the research proposed herein is to isolate, purify and characterize the enzymes which enable phages specific for these species to lyse their host cells. The lysis genes of two previously studied phages which are specific for S. mutans and A. naeslundii will be isolated, cloned and sequenced. To accomplish this, the complete genomes of these two phages will be sequenced, which will allow direct PCR subcloning of their holin and endolysin genes and characterization of their respective products. The DNA sequences of these holin/lysin gene pairs will provide information on their regulatory mechanisms and further our knowledge of the evolutionary relatedness of these viral proteins. Comparative analyses of their deduced primary amino acid sequences may also reveal conserved protein domains that are important in determining their structural and functional properties. Additional cloning experiments will be employed to isolate holin genes, and nearby endolysin genes, from these two phages and three additional oral phages, in order to develop a generally applicable method for directly isolating oral phage lysis genes. Phage DNA libraries will be constructed in a phage vector having a defective holin gene, which will allow recombinants expressing oral phage holins to be selected by complementation (plaque formation) of the defect in the phage vector. Inserts will then be sequenced to identify the phage holin genes and primers complementary to the ends of these genes will then be used to sequence, directly from the phage genomes, the adjacent, downstream endolysin genes. Selected endolysin genes will be subcloned, by PCR, from phage genomic DNAs, or from recombinant phage vectors, into expression vectors and introduced into E. coli in order to isolate and purify their gene products. The enzymatic activities of these proteins will then be extensively characterized, including determining the specific bonds which they cleave in the cell walls of their respective hosts. Purified preparations of these lytic enzymes might ultimately be used to kill, in a species-specific manner, S. mutans and A. naeslundii in dental plaque.

Summary: Oral HIV-1 transmission is well documented in children who become infected postnatally through breast milk. In contrast, epidemiological surveys have yielded conflicting data regarding oral HIV-1 transmission among adults, even though case reports have described infection in adults whose only risk was oral/genital contact. In earlier work, we exposed rhesus macaques of various ages to cell-free SIV. In neonates, viremia and AIDS developed after non-traumatic oral exposure to several strains, including chimeric SHIV containing HIV-1 env. In adult macaques, well controlled, non-traumatic experimental oral exposure to uncloned as well as molecularly cloned SIV resulted in systemic infection. Many questions regarding oral lentiviral infection remain unanswered, e.g., the tropism of the virus strains that can traverse the upper gastro-intestinal mucosal surfaces, the site(s) of viral entry, and the potential role of inflammation in the oral cavity in facilitating virus transmission. The Specific Aims of this proposal are to: 1. Test the hypothesis that macrophage (M)-tropic strains are transmitted preferentially after oral inoculation. 2. Test whether neonates are more susceptible to systemic infection after oral SIV inoculation than adults. 3. Test the hypothesis that the presence of inflammation in the oral cavity facilitates virus transmission. 4. Test whether the eruption of teeth (and its accompanying gingival inflammation) increases the susceptibility of infant macaques to orally administered SIV. 5. Determine site(s) of virus entry and initial target cells after oral inoculation. We will perform serial sacrifice experiments to identify the site(s) of SIV passage across the mucosa and the initial target cells. This work is significant because it will shed light on key aspects of the mechanisms involved in oral virus transmission in adult and neonatal primates, including identification of important cofactors in oral virus transmission. The data generated will help in formulating strategies to decrease the risks of oral HIV-1 transmission, including late virus transmission during breast feeding. transport and the roles of TC10 in cellular growth.

Project Title: MICROBIAL MEDIATORS OF TISSUE CELL BEHAVIOR Principal Investigator & Institution: Dmytryk, John J.; Professor; University of Oklahoma Hlth Sciences Ctr Health Sciences Center Oklahoma City, Ok 73126 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 30-JUN-2008 Summary: The overall goal of this proposed subproject is to further our understanding of how oral bacteria and their products directly influence the behavior of tissue cells within the periodontium, specifically gingival epithelial cells and connective tissue fibroblasts. The central hypothesis to be tested in this Subproject is that biofilm bacteria exert direct effects on tissue cell behavior within the periodontium. Our specific aims are: 1) to analyze the effects of mediators produced by Actinobacillus actinomycemcomitans (Aa) (released from planktonic or biofilm associated organisms) and microbial-induced mediators (epithelial defensins and supernatants from bacteria stimulated cell cultures) on the migration and proliferation of gingival epithelial cells and fibroblasts; and 2) to determine the effects of Aa-produced mediators and microbialinduced host tissue cell mediators on the synthesis of extracellular matrix proteins, cytokines and other cell signaling molecules by gingival epithelial cells and fibroblasts. Motility of gingival epithelial cells and fibroblasts will be analyzed using time-lapse videomicroscopy and computer-assisted image analysis. Cell migration and proliferation will be studied using an in-vitro wound model, in which a confluent monolayer of epithelial cells and fibroblasts is wounded and repopulation of the created wound space is measured over time. Synthetic activities of cells will be analyzed for production of collagen and non-collagen proteins, prostaglandins, cytokines, defensins,
16
Gingivitis
and defensin-like molecules. Although defensins have not been been detected in fibroblasts, this has not been adequately studied in situations where bacteria are in direct contact with connective tissues for extended periods of time. This is relevant to several clinical situations in periodontics, for example, exposed surgical materials, and in certain periodontal diseases characterized by bacterial invasion into gingival connective tissue, such as aggressive periodontitis and necrotizing ulcerative gingivitis. Collectively, this group of studies will further our understanding of the the effects of bacterial biofilms on epithelial and connective tissue cell behavior and metabolism in periodontal diseases and will pave the way for further studies focusing on how these pathogenic mechanisms may become targets for therapeutic intervention.

Project Title: MICROBIOLOGY/IMMUNOLOGY OF PERIODONTAL DISEASE IN T1DM Principal Investigator & Institution: Moore, Paul A.; Professor; Dental Public Health; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 31-AUG-2003 Summary: (provided by applicant): We propose to evaluate the periodontal disease, microbiology and immunology of a large adult Type 1 diabetic cohort and previously identified health control population. In 1992-1994, the University of Pittsburgh's Oral Health Science Institute (OHS) completed periodontal assessments of 406 subjects being followed by the ongoing University of Pittsburgh Epidemiology of Diabetes Complications Study (EDC). We propose to continue our collaboration by reexamining subjects in this cohort, who will now be 30 to 55 years old. This exploratory proposal will determine the prevalence, incidence and 10-year progression of periodontal disease of Type 1 diabetic and nondiabetic control subjects, and characterize the periodontal microflora and immune response within these populations. The overall goals of this proposal are to assess the impact of periodontal risk factors (diabetes, smoking, age of onset, elevated glucose, etc.) on disease progression microbiotas and immune responses. Additionally we plan to explore the interrelationships between periodontal infections and the incidence of coronary artery disease complications in this high-risk population. Because we have 10-year baseline periodontal disease data, we will be able to determine not only the prevalence, but also the incidence and site-specific progression of periodontal disease within this adult Type 1 diabetic cohort and an age-matched nondiabetic control group. In collaboration with the microbiology laboratory at Forsyth Dental Institute, we will be able to identify and quantify the gingival and periodontal microflora found within healthy and diseased sites of these populations. The impact of diabetic glycemic control (GhbA1, GhbA1-months, elevated fasting blood glucose) as well as salivary and GCF glucose concentrations will also be evaluated. The integration of this 10-year follow-up periodontal, microbiologic and immunologic assessment by the University of Pittsburgh's Oral Health Science Institute (OHSI) into this ongoing medical epidemiologic study (EDC) has several scientific and methodological benefits. The availability of a large Type 1 population having 10 years of baseline periodontal and medical data is a valuable asset. This inter-institutional collaboration has demonstrated reliable examination methodologies as well as the ability to share data management and statistical resources. An integrated multidisciplinary effort provides significant data collection capabilities essential for understanding the complex multifactorial etiology of periodontal disease in Type 1 diabetes.

Principal Investigator & Institution: Relman, David A.; Assistant Professor; Medicine; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2001; Project Start 01-SEP-2000; Project End 31-AUG-2004 Summary: (Adapted from the Investigator's Abstract): Bacteria are the primary cause of plaque-associated gingivitis and chronic adult periodontitis. It is unclear, however, whether the microorganisms responsible for gingivitis also contribute to the development of adult periodontitis or whether a unique assemblage of microorganisms is responsible for periodontitis. Studies indicate that plaque-associated gingivitis progresses to chronic adult periodontitis in only a subset of individuals. Previous work on this topic has been hampered by the limitations of cultivation-based methods, taxonomic inconsistencies, insufficient microbial characterization and inter-patient heterogeneity. The proposed work relies upon sensitive molecular methods to identify predictive associations between specific bacterial and archaeal species and the onset of adult periodontitis. The short-term objectives are to determine the subgingival microbial markers of gingival health, plaque-associated gingivitis and chronic adult periodontitis. The long-term objectives are to understand oral microbial ecology, to determine its relationship with local and systemic disease, and by so doing, to identify healthy individuals with increased risk of disease who would benefit from early intervention. The Specific Aims of this proposal are: Aim 1. Identify the bacterial and archaeal species within subgingival plaque from healthy sites in periodontitis patients. Phylogenetic analysis of 16S ribosomal DNA sequences and high density DNA microarrays will be used to identify the microbial species composition of subgingival plaque. Aim 2. Identify the bacteria and archaea from plaque-associated gingivitis and chronic adult periodontitis sites using the approach in Aim 1. Aim 3. Quantify differences in bacterial and archaeal contribution to the total microbial population within subgingival plaque associated with healthy gingiva, plaque-associated gingivitis and chronic adult periodontitis. Slot-blot and in situ hybridization methods will be applied with groupand species-specific 16S rDNA probes. Targeted organisms will include those implicated in the development of disease from the work in the above aims. Among the expected long-term benefits of this work will be the identification of organisms that can serve as predictors of intra-oral health and disease, and the development of broadly useful DNA microarray for microbial surveys and diagnostic studies.

Project Title: NEWLY IDENTIFIED ANTIGENS FOR GAMMA/DELTA T CELLS Principal Investigator & Institution: Bukowski, Jack F.; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2001; Project Start 01-AUG-1998; Project End 31-JUL-2002 Summary: (Adapted from Investigator's abstract): It is becoming evident that gamma/delta (gd) T cells play an important role in defense against bacterial and viral infections as well as in autoimmunity. gd T cells are expanded in humans with infectious diseases such as tuberculosis, salmonellosis, brucellosis, ehlichiosis, tularemia, malaria, leishmaniasis, mononucleosis, and in HIV (early stages). They are expanded in the synovium of patients with sarcoidosis. In contrast to alpha/beta (ab) T cells, which recognize peptide antigens in the context of MHC molecules, the predominant subset of gd T cells in human peripheral blood, termed Vg2Vd2 T cells, having no homologue in rodents, recognize unprocessed nonpeptide phosphate antigens in the absence of
18
Gingivitis
professional APC or known antigen presenting molecules. Abundant data describing in detail the interactions of the ab TCR with MHC-bound peptide have deepened our understanding of their role in infectious disease and in autoimmunity. In contrast, there is little information regarding the nature of interaction between the gd TCRs and their ligands. In fact, the identities of most microbial and autoimmune antigens reactive with gd T cells is unknown. Preliminary evidence in the investigator's laboratory shows that the TCR g junctional region is of crucial importance for the recognition of phosphate antigens by Vg2Vd2 T cells, arguing against a superantigen-like recognition of such antigens. The laboratory recently has found that alkylamines, which are major products of certain bacteria that cause gingivitis and many other diseases and are also found in plant foods and human body fluids, cause proliferation of Vg2Vd2 T cells in a TCRspecific manner. Alkylamine antigens are the first phosphate-free antigens described for Vg2Vd2 T cells and thus represent a distinct chemical class of ligand for Vg2Vd2 T cells. The investigator proposes to 1) Define the structural characteristics necessary for bioactivity of alkylamine antigens by testing a panel of naturally occurring alkylamine antigens for reactivity to gd T cells; 2) Identify specific domains and residues in the gd TCR important for recognition of alkylamine and phosphate antigens; 3) Determine the requirements of alkylamine antigens for antigen presentation and processing; 4) Define the phenotypes and alkylamine antigen reactivities of gingival gd T cells from patients with chronic gingivitis.

Project Title: NON-TOXIC ANTIMICROBIAL RINSE FOR GINGIVITIS Principal Investigator & Institution: Bhatt, Bakul M.; Biomedical Development Corporation 500 Sandau, Ste 200 San Antonio, Tx 78216 Timing: Fiscal Year 2003; Project Start 01-SEP-2000; Project End 31-AUG-2005 Summary: (provided by applicant): The overall goal of this proposal is to develop Iocide(r), a unique non-toxic, non-staining mouthrinse to treat gingivitis. Antimicrobial mouthrinses are valuable supplements to normal oral hygiene procedures and have demonstrated their ability to control plaque formation and prevent the onset of early periodontal disease. However, currently available antimicrobial rinses are either indicated only for short term use or demonstrate ineffective microbicidal activity. Chlorhexidine is the most effective antimicrobial mouthrinse available, but due to its side effects can only be used in acute settings. Other available animicrobial mouthrinses can be used over longer periods of time but are less effective than chlorhexidine in reducing oral bacteria. The Specific Aims of this grant are to 1) Optimize the Iocide(r) oral rinse formulation for use in the oral cavity, 2) Evaluate the safety profile in animals, and 3) Demonstrate its safety and efficacy in human clinical trials.

The applicants are leaders in the research and preclinical development of novel, nitric oxide based innovative technologies for the development of periodontal disease. In the Phase I application, we have presented

19
evidence that selenoethylguanidine (SEG) is a promising nitric oxide synthase (NOS) inhibitor with selectivity for the inducible nitric oxide synthase isoform (iNOS), and with an increased free radical scavenger activity, and proposed to perform pre-clinical studies in the rat to demonstrate its efficacy in gingivitis. The studies performed in the Phase I studies confirmed iNOS expression and peroxynitrite generation in periodontitis, and demonstrated the potent anti-inflammatory effects of SEG in a rat model of ligature-induced periodontitis. Further, we have demonstrated marked efficacy in the same experimental model with FP15, a novel peroxynitritie decomposition catalyst, and with PJ34, an inhibitor of the multifunctional nuclear enzyme poly(ADP-ribose) polymerase. These additional strategies specifically target NO-related downstream inflammatory pathways of periodontal inflammatory disease. In the current application, we propose to perform pre-clinical studies with SEG, FP15 and PJ34 in order to develop a lead candidate as treatments for gingivitis/periodontitis. The specific aims of the present proposal are to synthesize large quantities of the three test compounds, and perform studies in beagle dog models of gingivitis and periodontitis in order to obtain definitive proof of principle that the agents can reduce the tissue injury and inflammation. Based on the efficacy and safety data, a lead agent will be selected for further development for the experimental therapy of gingivitis and periodontitis. Additional aims of the current submission are to complete the pre-clinical pharmaceutical testing (GMP synthesis, advanced formulation, stability, and local irritation tests), to reach the stage of investigational drug application to the FDA. Throughout the work, Inotek Corporation collaborates with scientists at the University of North Carolina, a leading group in the experimental therapy of periodontal inflammation, as well as with leading contract research organizations to conduct GMP synthesis, formulation work and GLP animal safety testing.

Project Title: ORAL ANTIMICROBIAL PEPTIDES IN HEALTH AND DISEASE Principal Investigator & Institution: Dale-Crunk, Beverly A.; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2001; Project Start 01-AUG-1999; Project End 31-JUL-2004 Summary: Children have excellent defenses against oral infections. They lose deciduous teeth and erupt permanent teeth without infections and rarely get periodontal disease even in the presence of plaque. This project will investigate the role without infections and rarely get periodontal disease even in the presence of plaque. This project will investigate the role of beta- defensins, a newly recognized family of small, cationic peptides with anti- microbial activity, in oral health and disease susceptibility. Oral epithelia are constantly exposed to microbial challenges that lead to bacterially induced gingivitis, periodontal diseases and other infections. Recent findings show that mucosal epithelial cells, including gingival epithelial are the source of beta-defensins. These peptides are predicted to function as a first line of host defense against microbial pathogens and are now recognized as part of the innate or non-adaptive hot defense system. Two beta-defensin peptides, hBD-1 and hBD-2, are expressed and differentially regulated in gingival epithelial cells. This proposal is based on the hypotheses that (1) beta- defensin peptides produced by oral epithelial cells play an important role in determining the outcome of the host pathogen interaction at the oral mucosal barrier, (2) these peptides may be important in the normal protective function of the oral mucosa during development, and (3) variation in individual expression of these peptides may be a contributing factor to susceptibility to specific oral disorders in children and adults. These peptides have future potential for prevention and treatment of oral microbial

disorders, including periodontal disease, caries, recurrent candidal infections, and oral mucositis. The goals of this study encompass basic investigations and applied studies. We seek to understand the regulation of beta-defensin mRNA expression emphasizing epithelial differentiation and cell signaling pathways for expression upon stimulation by examples of commensal and pathogenic organisms, and by a two-component biofilm; to explore the relationship of beta-defensin expression and that of inflammatory cytokines; to determine beta-defensin expression in non- invasively collected oral samples from children, and to explore variation in defensin expression as a function of age and to test the hypothesis that defensin expression has correlated with oral health status in test populations in collaboration with other Comprehensive Center investigators.

Project Title: ORAL MICROBIAL ASSOCIATIONS IN HIV+SUBJECTS Principal Investigator & Institution: Paster, Bruce J.; Senior Member of Staff; Forsyth Institute Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2004 Summary: (provided by applicant): The broad objectives of this proposal are to examine the hypothesis that the more common periodontal infections in HIV+ subjects are caused by specific bacterial or fungal species, which are not necessarily the typical putative periodontal pathogens usually found in comparable periodontal infections in HIV negative subjects. Our preliminary data indicated that HIV+ subjects with necrotizing ulcerative periodontitis (NUP), a more severe periodontal disease unique to these individuals, indeed lacked many of the classical periodontal pathogens, but instead possessed "unusual" taxa, such as Bulleidia extructa and Dialister pneumosintes, and novel "uncultivable" phylotypes of the genera Dialister, Peptostreptococcus, Selenomonas, and members of the "uncultivable" phylum TM7. Our objectives are addressed in two Specific Aims. Aim 1 will identify the predominant cultivable and notyet-cultivated bacteria and fungi that are associated with periodontal infections in HIV+ subjects, such as gingivitis, low/moderate and severe adult periodontitis, and Linear Gingival Erythema (LGE), another periodontal infection unique to HIV+ subjects. These studies will be performed by analyzing bacterial 16S rRNA and fungal 18S rRNA gene sequences of inserts in clones from plaque libraries. The libraries will be generated by PCR amplification of rRNA genes present in subgingival plaque followed by ligation of the amplicons into appropriate vectors and by transformation of E. coli. The sequence of each clone will be used to determine species identity, or if unknown, its phylogenetic position. It is anticipated that 25 to 50 additional new taxa will be identified. Aim 2 will test the hypothesis that specific bacterial and fungal species are associated with periodontal infections with the deterioration of immune status in HIV+ patients. In each periodontal disease category, 25 subjects with high viral loads and low CD4 levels and 25 subjects with low viral load and high CD4 levels will be analyzed. Comparisons of subgingival microbial and fungal populations will be made between these HIV+ groups vs. control groups of HIV negative subjects. Up to 200 predominant bacterial species will be assayed for each sample using Checkerboard hybridization, which allows for the simultaneous analysis of multiple samples with multiple probes. Up to 30 fungal species will be assayed for each sample in a second, separate checkerboard hybridization. It is likely that specific bacterial complexes (e.g., specific combinations of bacteria/fungi) are associated with these periodontal diseases and may change with the severity of HIV infection. The proposed studies may provide insight for the identity of putative pathogens in comparable periodontal infections in HIV negative individuals.

Project Title: ORAL TRANSMISSION OF A FLUORESCENT SIV Principal Investigator & Institution: Sodora, Donald L.; Assistant Professor; Internal Medicine; University of Texas Sw Med Ctr/Dallas Dallas, Tx 753909105 Timing: Fiscal Year 2001; Project Start 01-FEB-1999; Project End 31-JAN-2004 Summary: Oral transmission of HIV is one of the factors fueling the current AIDS pandemic. Here we utilize the simian immunodeficiency virus (SIV)/macaque AIDS animal model to investigate the early events following oral transmission. We hypothesize that the very early events in mucosal transmission are crucial to determining whether or not an infection occurs. By investigating these earliest events, a clear picture will emerge as to how infection via the oral route occurs and why a successful HIV/SIV infection is only observed after some oral inoculations. A fluorescently labeled SIV (SIVmac239gfp) will be used to enable us to identify the cell infected very early after the virus inoculation (Aim 2). Low doses of virus will be used to assess the role of an inflamed gingivitis mucosa in SIV transmission (Aim 2). The role of gingivitis will be assessed in juvenile macaques and the role of inflamed gums associated with the cutting of teeth will be assessed in infants. Transient infections represent an important disease outcome in which the virus is detected several weeks post-inoculation but can not be detected at later time points. We will investigate both virologic and immunologic aspects of transient infections (Aim 3). This study will include an assessment of the number of SIV responsive T-cells in macaques utilizing a new assay developed by Dr. Louis Picket at the University of Texas Southwestern Medical Center. PBMC's will be obtained from SIV vaccinated, SIV infected and uninfected macaques and assessed for the ability to produce cytokines in the presence of SIV antigens through a flow cytometric analysis. In total these studies are designed to assess the entry of virus via the oral mucosa, follow the virus as it disseminates throughout the macaque and to assess the factors which influence a successful or abortive oral transmission.

Project Title: ORAL TREPONEMES IN PERIODONTAL DISEASES Principal Investigator & Institution: Ebersole, Jeffrey L.; Director; Oral Health Practice; University of Kentucky 109 Kinkead Hall Lexington, Ky 40506 Timing: Fiscal Year 2001; Project Start 30-SEP-1994; Project End 30-APR-2003 Summary: (adapted from the Investigator's abstract): There is a growing awareness that oral treponemes play a role in the progression from health to periodontitis. Despite the interest in the relationship of this genus to periodontitis, only a few Treponema spp. have been isolated and grown. Substantial literature has implicated Treponema denticola as an oral pathogen: however, few investigations have examined other species. These investigators have discovered that the predominant cultivable oral spirochete in subgingival These investigators propose to investigate T. pectinovorum virulence components and its potential contribution to the tissue and cellular destruction observed vitro and in vivo models which have been developed during the initial phases of the grant. The hypothesis to be tested is that T. pectinovorum is a major this organism presents unique outer membrane proteins and an LPS-like molecule distinctive from other oral treponemes, the hypothesis to be tested is that the 42 kDa major outer membrane protein (MompA) and the LPS like molecule (LPSL) have characteristics of virulence components in in vitro and in vivo models of disease. Successful testing of these hypotheses would imply that T. pectinovorum utilizes these components in subgingival plaque ecology to contribute to the soft tissue destructive and bone

Project Title: PERIODONTITIS AND SYSTEMIC DISEASE: CONFOUNDING? Principal Investigator & Institution: Hujoel, Philippe P.; Professor; Dental Public Health Sciences; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2001; Project Start 01-SEP-2000; Project End 30-JUN-2004 Summary: Periodontitis has been associated with systemic diseases such as cardiovascular disease and low birth weight. Establishing the causality of these associations is difficult; the compared groups, individuals with and without periodontitis, may differ on factors other than periodontitis. If these other factors are causally related to systemic disease risk, confounding may be present. The primary goal of this R03 proposal is to provide a methodological study of confounding by means of different approaches. This methodological work will be performed in three large databases: the First National Health & Nutrition Examination Survey (NHANES I) (n=31,973), the NHANES I Epidemiological Follow-up Study (NHEFS) (n=11,348), and the Third National Health & Nutrition Examination Survey (NHANES III) (n=30,818). Exhaustive information regarding most potentially confounding variables is present in these datasets (greater than 1000 variables per individual). Preliminary analyses of the NHANES I and NHEFS suggest that confounding is a significant methodological challenge. Periodontitis was associated with unexpected differences that may in and of itself cause other systemic diseases. Individuals with periodontitis, after adjustment for age and gender, were more likely to have an unhealthy diet (less fruit, less vitamin C, less riboflavin, and less linoleic acid), were more likely to have suffered a nervous breakdown, less likely to exercise, more likely to be overweight, and more likely to have high blood pressure. In addition, after adjustment for known risk factors, periodontitis was associated with a two-fold increase in lung cancer mortality, an unexpected finding that suggests that confounding may have a strong influence. The aims of this study are: 1) to provide a systematic evaluation of potentially confounding variables in NHANES I and NHANES III; 2) to provide a systematic evaluation of the association between periodontitis and the most common causes of mortality in NHEFS, 3) to assess the benefits of using alternate referent or unexposed groups in cohort studies in NHEFS; and 4) to perform a series of sensitivity analyses to assess the extent to which confounding variables may cause spurious associations. The investigators believe the completion of these projects may play a pivotal role in determining whether the

Project Title: RAGE AND MECHANISMS OF VASCULAR AND MONOCYTE DYSFUNCTION Principal Investigator & Institution: Schmidt, Ann M.; Professor; Physiology/Cellualr Biophysics; Columbia University Health Sciences New York, Ny 10032 Timing: Fiscal Year 2003; Project Start 01-FEB-1999; Project End 31-JAN-2004 Summary: Sustained endothelial and mononuclear phagocyte dysfunction is critical to the pathogenesis of chronic vascular disorders. Non-enzymatic glycoxidation of proteins and lipids forming Advanced Glycation Endproducts (AGEs) in the vasculature and tissues is accelerated in atherosclerosis, diabetes and renal failure. Interaction of AGES with Receptor for AGE (RAGE) on endothelium and monocytes perturbs cellular properties critical to vascular and tissue homeostatic processes, and causes chronic cellular activation. The central hypothesis of the Program Project is that AGE-RAGEmediated modulation of endothelial and monocyte functions compromises physiologic effector mechanisms and eventuates in aggressive atherosclerosis, delayed wound repair, and impaired resolution of local inflammation. Employing glucose intolerance as the stimulus for enhanced AGE formation, our pilot studies have shown that antagonism of AGE-RAGE interaction suppresses accelerated atherosclerosis, ameliorates wound healing and diminishes inflammatory consequences of soft tissue infection. Project 1 will exploit our recently developed murine model of accelerated atherosclerosis associated with glucose intolerance to probe the role of RAGE in rapid formation of vascular lesions. Project 2 will extend our concept to a secondary intention wound model in insulin- resistant mice in which AGE-RAGE-mediated cellular dysfunction underlies compromised tissues reparative mechanisms. Project 3 will focus on local inflammation/infection in AGE-rich soft tissues using a model of gingivitis triggered by bacterial infection. The overlapping host response mechanisms triggered by atherogenesis, wound repair and local inflammation, the intimate involvement of endothelium and monocytes, as well as the central role of AGE binding to RAGE, provide the basis for close interactions among the three Projects. By collaborative studies between each of the Projects, the contribution of RAGE will be determined using transgenic mice and mutated RAGE molecules. At the end of this Program Project, we expect to have generated new and important information related to vascular and monocyte dysfunction underlying accelerated atherosclerosis, impaired wound healing and the compromised host response to local inflammation common to disorders characterize by tissue deposition of AGEs. These data should provide insight into a novel target for the development of future therapeutic agents. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: SALIVARY PROTEINS IN DENTAL INTEGUMENTS Principal Investigator & Institution: Oppenheim, Frank G.; Professor and Chair; Periodontology; Boston University Medical Campus 715 Albany St, 560 Boston, Ma 02118 Timing: Fiscal Year 2001; Project Start 01-JAN-1983; Project End 31-MAY-2005 Summary: The acquired enamel pellicle is a protein film readily formed on tooth mineral surfaces in the oral environment. It has been established that its formation is driven by the adsorption of proteins and peptides derived from oral fluid. Most of these
24
Gingivitis
proteins originate from either parotid or submandibular/ sublingual secretions which undergo modifications in the oral cavity before or after adsorption to the hydroxyapatite crystallites of tooth enamel. The composition and the structure of this acquired enamel pellicle are still largely unknown but play functionally a vital role with important physiological/clinical implications. A major thrust of this application is to use state-ofthe-art proteomics to identify and characterize the major components of the in-vivo formed pellicle. Since the pellicle has an inner aspect facing the tooth surface and an outer aspect connected to the bacterial biofilm known as Dental plaque the functions of pellicle are multifaceted and complex. Another major goal is to investigate the protective functions of the pellicle vis-a-vis the maintenance of the mineral phase of enamel and the interplay between molecular entities of the pellicle and those bacteria which constitute the early colonizers of the biofilm forming on the tooth surface. The nature of the pellicle with respect to the early attachment of bacteria including those which are known periodontal pathogens will be studied in vitro and in vivo. The Specific Aims of the project are to: 1) Characterize components from pellicles formed in vivo by a variety of isolation techniques including 2D-electrophoresis followed by proteomic analyses comprising MALDI-TOF MS. LC-ESI MS and LC-MS/MS; 2) Explore the protective functions of the enamel pellicle by determining the affinity of its components to hydroxyapatite, the inhibitory potential of pellicle proteins/peptides of calcium phosphate precipitation from supersaturated solutions, and the capacity to retard demineralization; 3) Determine in vitro binding parameters of individual early pellicle colonizers, assess the role of transglutaminase in pellicle-bacterial interactions and employ biomimetic approaches to modify functional aspects of pellicle components; 4) Investigate with the checkerboard DNA-DNA hybridization assay the in vivo binding of early pellicle colonizers in healthy individuals and gingivitis patients, assess the relative role of exocrine and serum derived proteins/peptides on pellicle colonization in vivo and explore effects of different local environments in the oral cavity on these processes.

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.3 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with gingivitis, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “gingivitis” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for gingivitis (hyperlinks lead to article summaries):

CHAPTER 2. NUTRITION AND GINGIVITIS Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and gingivitis.
Finding Nutrition Studies on Gingivitis The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.4 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “gingivitis” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 5. PATENTS ON GINGIVITIS Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.5 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “gingivitis” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on gingivitis, we have not necessarily excluded non-medical patents in this bibliography.

Alcohol free mouthwash Inventor(s): Chaudhari; Atma (Scarborough, CA), Pan; Pauline (Morris Plains, NJ), Scheurer; Heinrich (Scarborough, CA), Volpe; Frank (Kinnelon, NJ) Assignee(s): Warner-Lambert Company (Morris Plains, NJ) Patent Number: 5,817,295 Date filed: January 28, 1997 Abstract: A pleasant-tasting, substantially alcohol-free oral mouthwash composition is effective in eliminating the bacteria and other oral microflora responsible for the production of plaque, periodontitis, gingivitis, gum disease and bad breath. The composition consists of a unique blend of the essential oils thymol or eucalyptol, methyl salicylate, menthol and tripartite blend of peppermint flavor oils that are dissolved in solution using a non-ionic surfactant blend. Excerpt(s): The invention relates generally to oral mouthwashes for the prevention and elimination of bad breath as well as the reduction of oral microflora responsible for the development of plaque. Dental plaque can lead to tooth decay, gingivitis and other related gum disease. In particular, the present invention relates to an alcohol free mouthwash that is effective in preventing those problems and is pleasant tasting as well. Oral rinse and mouthwash compositions have been used by people for many years for the prevention of bad breath and for the elimination of bacteria and other oral microorganisms that are responsible not only for bad breath but also tooth decay, plaque and gum disease such as gingivitis and periodontitis. To this end mouthwashes in the past have been designed to clean the oral cavity, provide fresh breath and kill the harmful bacteria. Conventional mouthwashes have always contained fairly high levels of ethyl alcohol with percentages ranging from approximately 10% up to about 30% by volume. Alcohol is used both as a disinfectant and as a solvent in which other additives such as astringents, fluorides, color additives, flavor oils, bactericidal actives and the like can be dissolved and then dispersed into solution. High levels of alcohol are generally used to provide a disinfection function since lower concentrations are sufficient to dissolve and disperse the various components into solution. Alcohol also provides a preservative role for the mouthwash during storage and use as well as enhancement of flavor oil organoleptic cues. Web site: http://www.delphion.com/details?pn=US05817295__

Anti-inflammatory composition comprising tetracycline Inventor(s): Gardner; Wallace J. (1791 Mass Ave., Cambridge, MA 02140) Assignee(s): none reported Patent Number: 6,610,274 Date filed: December 18, 2001 Abstract: Therapeutic composition having anti-infective activity. The therapeutic composition is a formulation comprising an antibiotic, preferably a tetracycline, most preferably doxycycline, which has not been chemically modified to eliminate antimicrobial efficacy. The antibiotic is preferably in a liquid vehicle, most preferably
Patents 75
one that contains at least 20% alcohol by volume. The therapeutic composition is preferably in local delivery form and is self-administered orally or via the nasal cavity. Administration of the therapeutic composition of the present invention treats diseases that originate from the oral cavity or that do not originate in the oral cavity, but are affected by contaminants, such as viruses or bacteria, in the oral cavity entering the bloodstream including but not limited to periodontal disease, sinusitis, gingivitis, the common cold, sore throat, influenza, allergies (particularly to tree pollen), resistant pneumonia, diseases of the gastrointestinal tract, inflammatory diseases such as rheumatoid arthritis, cancer, ulcers, heart disease, etc. Excerpt(s): The accumulation bacteria in the oral cavity, such as on the teeth or tongue has been identified as a contributor or cause of various inflammatory conditions, including gingivitis, periodontitis and other gum diseases. Treatment of the oral cavity with antibiotics to reduce or eliminate the effects of bacteria is known. For example, broad spectrum antibiotics such as tetracyclines and metronidazole have been used in the treatment of periodontal disease to reduce oral cavity microflora. Typically such use has been systemic, which can result in various undesirable side effects, including the threat or danger or building allergies or immunity to the antibiotic, overgrowth of opportunistic yeast and fungi and intestinal disturbances. Many other common inflammatory diseases, such as sinusitis, diseases of the gastrointestinal tract (including those that manifest themselves in stomach and bowel problems), the common cold, influenza, allergies, halitosis, pneumonia, etc., also may be caused by viruses and/or bacteria. Often the source of the bacteria and viruses is the oral cavity, especially the ear, nose and throat passages, and the sinuses. Once the bacteria and/or viruses are resident in the oral cavities or sinuses (e.g., the maxillary, frontal and ethmoid), they can continually cause infection through circulation in the blood stream. Continual reduction or elimination of these bacteria and viruses would reduce chronic infection in the body. The problems of the prior art have been overcome by the present invention, which provides a therapeutic composition having anti-infective activity. In a preferred embodiment, the therapeutic composition is a formulation comprising an antibiotic, preferably a tetracycline, most preferably doxycycline, which has not been chemically modified to eliminate antimicrobial efficacy. The antibiotic is preferably in a liquid vehicle, most preferably one that contains at least 20% alcohol by volume. The therapeutic composition is preferably in local delivery form and is preferably selfadministered orally or via-the nasal cavity. The therapeutic composition most preferably is a self-delivered formulation in local delivery form that consists essentially of a tetracycline, most preferably doxycline, which has not been chemically modified to eliminate antimicrobial efficacy, and a liquid vehicle, more preferably one which contains at least 20% alcohol by volume, and most preferably one which consists essentially of sterile water or Listerine or the like, which tetracyline is preferably present in the formulation in the amount of between 50 to 100 mgs per ounce of liquid vehicle.

Gingivitis
Abstract: The present invention provides a novel chewing gum product generally for the lysis and killing of oral microbes. In a preferred embodiment, the chewing gum product comprises an antimicrobial metal ion component and an inorganic ceramic carrier, and provides a concentration of such substances from about 0.05 to 50 weight percent of the chewing gum. In particular, these compositions may comprise zeolites ion-exchanged with antimicrobial metals, in addition to other oral care compounds. The present invention also relates to methods of using such compositions for treating and inhibiting dental caries, dental plaque and gingivitis, oral malodor and periodontal conditions. The compositions of the present invention may be incorporated into chewing gum according to conventional methods used in the art. Excerpt(s): The present invention relates to chewing gum products containing an antimicrobial agent for killing microbes, particularly oral bacteria, for reducing or preventing dental plaque and caries and gingivitis, and to methods for treating the same, and the like. There is a need in the dental arts for an improved means of promoting dental health and hygiene, including a means for reducing plaque and dental caries, gingivitis, and especially for killing microbes which cause these dental problems, as a result of improper and inadequate tooth brushing. Plaque may be removed to some extent by effective brushing of the teeth. However, some areas of the teeth, which are less accessible and cannot be easily reached by a toothbrush, are particularly susceptible to plaque formation and consequently to calculus. Left unhindered, the plaque increases in size and more tenaciously adheres to the teeth. Although brushing with a toothbrush and dentifrice is a widely recognized technique for maintaining dental health, the average person brushes only once a day for approximately one minute. Therefore, a great need exists for finding additional methods for improving daily oral hygiene. Dental caries, which cause the progressive decay of teeth, are manifested by localized demineralization, caused by acids produced from bacteria that ferment carbohydrate foods. The process may begin when bacteria in the mouth adhere to a tooth surface, thereby forming a dental plaque. The plaque is a product of microbial growth, primarily derived from food residues in the mouth. Mucoproteins and minerals present in saliva and dead cells in the mouth also contribute to plaque formation. There is substantial evidence that dental plaque is the predominant etiological factor responsible for both dental caries and periodontal disease, due to the generation of acids within the plaque structure. Thus, dental compositions having antimicrobial properties are beneficial for killing oral bacteria that contribute to the formation of dental plaque.

Composition for enhancing oral hygiene Inventor(s): Ahn; Ho Jeong (Youseong-ku, KR), Bak; Hong Soon (Youseong-ku, KR), Chang; Sug Youn (Youseong-ku, KR), Choi; Eu Jene (Songpa-ku, KR), Choi; Jong Heon (Dong-ku, KR), Ha; Jae Mong (Youseong-ku, KR), Kim; Moon Moo (Youseong-ku, KR), Lee; Seung Joon (Seo-ku, KR), Lim; Hyeong Jun (Youseong-ku, KR) Assignee(s): LG Chemical Ltd. (Seoul, KR) Patent Number: 5,817,297 Date filed: January 29, 1997 Abstract: The present invention relates to a composition for enhancing oral hygiene which can effectively prevent and treat periodontal diseases and dental caries, characterized in that it contains as an effective component one or more component selected from ursodesoxycholic acid and chenodesoxycholic acid having a good inhibiting effect on collagenase, which is known as the inducer of gingivitis. Excerpt(s): The present invention relates to a composition for enhancing oral hygiene which is effective for the prevention and treatment of periodontal diseases and for the prevention of dental caries. More specifically, the present invention relates to a composition for enhancing oral hygiene which can effectively prevent and treat periodontal diseases and dental caries, characterized in that it contains one or more component selected from ursodesoxycholic acid and chenodesoxycholic acid having a good inhibiting effect on collagenase activity, as an effective component. Various oral diseases occurring in the oral tissues are caused by plaque formed by the action of numerous microorganisms present in oral cavity. Their importance in clinical and pathological view has been widely studied and also identified by many reseachers including Alexander (Alexander A. G., J. Periodent, 42, 21-28, 1971), Ash(Ash, M. M., J. Periodontol, 35, 424, 1964), etc. Saliva is a unique mixture comprising electrolytes and other constituents, which play an important role in maintenance of oral health and digestion. The saliva contains various enzymes of which some enzymes including metalloproteinase show an enhanced enzymatic activity in patients suffering from periodontal diseases. Therefore, saliva enzymes are the important subject of study in view of prevention and treatment of periodontal diseases. Generally, it has been known that salivary gland, serum, leukocytes, epithelial cells, oral microorganisms, etc. are involved in production of such saliva enzymes.

Device and method to treat oral disease in felines Inventor(s): Moran; Kelly (495 Main St., Wilbraham, MA 01095), Morello; Carol (495 Main St., Wilbraham, MA 10195), Morello; Jane (89 Springfield St., Wilbraham, MA 01095), Muller; Kimberly A. (16 Puritan Valley, Brookfield, CT 06804), Siminovsky; Bill (1301 Trumansburg Rd., Ithaca, NY 14850) Assignee(s): none reported Patent Number: 5,941,701 Date filed: July 14, 1998 Abstract: A laser system and method are described that will effectively interrupt the progression of periodontal disease in felines, particularly in situations where the disease has progressed to advanced stages of periodontitis and feline lymphocytic-plasmacytic gingivitis stomatitis. A laser system is employed to achieve precision in surgical procedures where the working field is limited due to the anatomical structure of a feline's mouth. The laser system is also capable of effectively sealing tubules and of eradicating bacteria in the periodontium to significantly reduce the risk of infection. Additionally, the laser therapy can be preceded by pretreatment methods to effectively interrupt the progression of periodontal diseases. Excerpt(s): The present invention relates to a device and method to treat periodontal disease in felines, particularly in situations where the disease has progressed to advanced stages of periodontitis and feline lymphocytic-plasmacytic gingivitis (commonly referred to as feline lymphocytic-plasmacytic stomatitis). Oral diseases are especially prevalent in cats. Periodontal disease can range from a localized inflammation of the gingiva (gingivitis) to inflamation and destruction of the gingiva, alveolar bone, the periodontal ligament, and tooth structure (periodontitis). Etiology of the disease can involve plaque, calculus, and systemic inflammatory response. Generally, the protocol for treating periodontal disease focuses on cleaning the oral cavity, repairing the tissue, and stopping the progression of the disease. However, the available treatment methods, which include scalping, polishing, curettage, dental extractions, root planing, gingivectomies and in extreme cases, gingival flaps or grafts, are inadequate when treating advanced periodontitis and feline lymphocytic-plasmacytic gingivitis/stomatitis.

Dual phase stannous oral compositions Inventor(s): Dixon, Jr.; Cloyd (Covington, KY), Glandorf; William M. (Mason, OH), Jacobs; David S. (Hamilton, OH), Walden; Gary L. (West Chester, OH), Wireko; Fred C. (West Chester, OH) Assignee(s): The Procter & Gamble Company (Cincinnati, OH) Patent Number: 6,521,216 Date filed: November 10, 2000 Abstract: The present invention relates to dual phase oral compositions providing effective antimicobial activity for reducing plaque and gingivitis. One of the phases of the dual phase composition will contain stannous. The stannous phase comprises a stannous ion source, a fluoride ion source, and a gluconate salt. The stannous phase is essentially free of either an abrasive polishing material or chloride ions. The stannous
Patents 79
phase containing phase inhibits the formation of a stannous chloro gluconate complex. The present invention also provides a method for effective delivery of stannouscontaining compositions. Excerpt(s): The present invention relates to improved dual phase oral compositions containing stannous salts, such as stannous fluoride. These improved compositions provide a spectrum of intraoral benefits derived from stannous fluoride and/or other stannous salt, including antimicrobial effects, control of breath malodor, control of dental plaque growth and metabolism, reduced gingivitis, decreased progression to periodontal disease, reductions in dentinal hypersensitivity and reduced coronal and root dental caries. The improved stannous containing compositions provide high efficacy by having the stannous stabilized in a separate phase from the rest of the composition. The stannous is stabilized without increasing the negative aesthetics associated with stannous and ingredients commonly used to stabilize stannous. This improvement results in a more aesthetically pleasing, particularly less astringent, oral composition compared to other oral composition with the same efficacy. Stannous fluoride is commonly known for its efficacy when formulated into oral products. Stannous fluoride was the first fluoride source incorporated into toothpastes for therapeutic efficacy in the control of dental caries. Stannous fluoride gels, rinses, and dentifrices have since been shown to provide clinical efficacy for the reduction of dental caries, dentinal hypersensitivity, dental plaque and gingivitis. In addition to these clinical effects, formulations containing stannous fluoride may also help to provide improved breath benefits through chemical and antibacterial actions. Stannous fluoride formulations typically include stabilization systems designed to maintain bioavailable (i.e., soluble and active) levels of stannous during shelf storage, accounting for loss of stannous to oxidation, hydrolysis or precipitation. Therefore, stannous fluoride formulations may contain other additional stannous containing ingredients, which may provide important stabilization benefits for efficacy. High concentrations of stannous in dental formulations helps to ensure stability of stannous fluoride and therefore clinical efficacy of formulations containing the latter. Unfortunately, although stannous fluoride compositions are known to be highly effective, successful commercial utilization is complicated by complexity in the development of formulations providing adequate stannous fluoride stability and in the side effects of stannous. Formulations providing increased or improved efficacy typically promote increased side effects. This limits clinical and commercial applications. A negative side effect routinely encountered during use of effective stannous fluoride formulations is unacceptable formulation astringency. Astringents are locally applied protein precipitants that have low cell permeability, thus restricting actions to cell surfaces and interstitial spaces. Strong astringents can induce contraction and wrinkling of the tissues and mucous secretions can be precipitated or reduced. Within oral products, these chemical actions produce an unpleasant `drying` sensation in the oral cavity, such as on the tongue, gingival tissues or buccal epithelia. Stannous formulations containing sufficient stannous for bioavailability are routinely described as astringent by patients and consumers and this property is undesirable. The astringency is most noticeable after use of the product. Astringency is caused by stannous and by ingredients commonly used to help stabilize stannous, such as citrate and gluconate. Another commonly found side effect from the regular use of stannous fluoride is cosmetic yellow-brown tooth staining. This stain is derived from pellicle, plaque and dietary component reactions with available stannous deposited on tooth surfaces during treatment with effective stannous fluoride formulations.

Fast dissolving orally comsumable films Inventor(s): Kumar; Lori D. (Skillman, NJ), Leone; Robert S. (Fanwood, NJ), Leung; SauHung Spence (Parsippany, NJ) Assignee(s): Warner-Lambert Company (Morris Plains, NJ) Patent Number: 6,596,298 Date filed: September 14, 1999 Abstract: Physiologically acceptable films, including edible films, are disclosed. The films include a water soluble film-forming polymer such as pullulan. Edible films are disclosed that include pullulan and antimicrobially effective amounts of the essential oils thymol, methyl salicylate, eucalyptol and menthol. The edible films are effective at killing the plaque-producing germs that cause dental plaque, gingivitis and bad breath. The film can also contain pharmaceutically active agents. Methods for producing the films are also disclosed. Excerpt(s): This invention relates to fast dissolving orally consumable films. The films are used to deliver breath deodorizing agents, antimicrobial agents and salivary stimulants to the oral cavity. The films can also be used to deliver pharmaceutically active agents. In a more perfect world, people would thoroughly cleanse their mouths after each meal as part of their routine oral hygienic practices. Unfortunately, several factors conspire to prevent widespread compliance with this basic requirement of a good oral cleaning regimen. Oral cleansing can be difficult or inconvenient at times, depending on the nature of the cleansing and the situation in which the cleansing must occur. Brushing, flossing, cleaning your tongue and gargling using a variety of devices and compositions well-suited for the privacy of one's home are common oral care practices. However, the devices and compositions used in oral cleansing practices are less convenient to use away from home, where bathroom facilities might be scarce, unavailable or unsanitary.

Immunogenic compositions comprising porphyromonas gingivalis proteins and/or peptides and methods Inventor(s): Genco; Caroline Attardo (Atlanta, GA), Potempa; Jan (Athens, GA), Travis; James (Athens, GA) Assignee(s): Morehouse School of Medicine (Atlanta, GA), The University of Georgia Research Foundation, Inc. (Athens, GA) Patent Number: 6,129,917 Date filed: March 21, 1997 Abstract: Provided herein are methods and immunogenic compositions useful for protecting mammals from infection and pathology of P. gingivalis. Specifically, arginine-specific proteases of Porphyromonas gingivalis and peptides derived therefrom offer protection against infection. Immunogenic compositions comprising a 50 kDa arginine-specific protease, the high molecular weight complex or peptides from one of the foregoing proteins are capable of protecting against P. gingivalis infection and/or gingivitis and/or periodontitis caused thereby in mammals, including humans. Excerpt(s): The field of this invention is immunogenic compositions comprising bacterial proteases and/or peptides derived therefrom, more particularly those of
Patents 81
Porphyromonas gingivalis, most particularly the arginine-specific proteases and immunogenic compositions containing Arg-gingipains and/or peptides derived therefrom, and the lysine-specific proteases termed Lys-gingipains herein and immunogenic compositions containing Lys-gingipain(s) and/or peptides derived therefrom. Those immunogenic compositions are useful in the protection of a mammal, including a human, from infection and pathology caused by P. gingivalis. Porphyromonas gingivalis (formerly Bacteroides gingivalis) is an obligately anaerobic bacterium which is implicated in periodontal disease. P. gingivalis produces several distinct proteolytic enzymes; its proteinases are recognized as important virulence factors, together with other factors such as lipopolysaccharide and a polysaccharide capsule, fimbriae, lectin-like adhesins, hyaluronidase, keratinase, superoxide dismutase and hemagglutinating and hemolyzing activities. A number of physiologically significant proteins, including collagen, fibronectin, immunoglobulins, complement factors C3, C4, C5, and B, lysozyme, iron-binding proteins, plasma proteinase inhibitors, fibrin and fibrinogen, and factors of the plasma coagulation cascade system, are hydrolyzed by P. gingivalis proteases. Broad proteolytic activity plays a role in the evasion of host defense mechanisms and the destruction of gingival connective tissue in progressive periodontitis [Saglie et al. (1988) J. Periodontal. 59:259-265]. Progressive periodontitis is characterized by acute tissue degradation promoted by collagen digestion and a vigorous inflammatory response characterized by excessive neutrophil infiltration [White and Maynard (1981) J. Periodontal Res. 16:259-265]. Gingival crevicular fluid accumulates in periodontitis as periodontal tissue erosion progresses at the foci of the infection, and numerous plasma proteins are exposed to proteinases expressed by the bacteria at the injury site. Neutrophils are recruited to the gingiva, in part, by the humoral chemotactic factor C5a. The complement components C3 and C5 are activated by complex plasma proteases with "trypsin-like" specificities called convertases [Muller-Eberhard (1988) Ann. Rev. Biochem. 57:321-347]. The human plasma convertases cleave the.alpha.-chains of C3 and C5 at a specific site generating biologically active factors known as anaphylatoxins (i.e. C3a and C5a). The anaphylatoxins are potent proinflammatory factors exhibiting chemotactic and/or spasmogenic activities as well as promoting increased vascular permeability. The larger products from C3 and C5 cleavage (i.e. C3b and C5b) participate in functions including complement cascade activation, opsonization, and lytic complex formation.

The appliance may also be used to stimulate gum junctional epithelium adhesion in the treatment of, for example, gingivitis and periodontitis. Excerpt(s): The present invention relates to the attachment of cells to shaped articles. More specifically, the invention relates to the attachment of epithelial cells to laminin 5coated biologically compatible implants and trans-epithelial appliances. When organs of
82
Gingivitis
the body are formed, they develop in neatly organized arrays. Often, cell types are separated by connective tissue called basement membranes. In skin, for instance, the superficial layer of epidermal cells adheres to the underlying basement membrane. This skin basement membrane acts as a barrier between the epidermal cells on the outside, and the dermal cells underneath. A similar arrangement of cells occurs in the lining of the gut and in the oral cavity. Basement membranes have been implicated in the growth, attachment, migration, repair and differentiation of their overlying cell populations. Three layers have been defined in basement membranes: a) the lamina lucida, an electronmicroscopically clear region in close approximation to the overlying cells; b) the lamina densa, an electron dense region of 20-300 nm in width; and c) the sublamina densa which contains anchoring fibrils, microfibrillar bundles and collagen fibers.

Lysine decarboxylase inhibitors for the prevention and treatment of periodontal disease Inventor(s): Levine; Martin (505 Kensington Rd., Norman, OK 73072) Assignee(s): none reported Patent Number: 6,103,220 Date filed: January 22, 1999 Abstract: An agent,.alpha.-difluoromethyl lysine (DFML) or.alpha.-monofluoromethyl lysine (MFML), inhibits lysine decarboxylases produced by bacteria associated with periodontal tissues. Inhibition of such lysine decarboxylases can prophylactically and therapeutically treat periodontal diseases such as gingivitis and periodontitis. The agent may be incorporated into toothpastes, mouthwashes, irrigation solutions, tablets, periodontal treatment packs, or an adhesive paste or film coatings for applying to the teeth. Excerpt(s): Adult periodontal disease is a widespread medical problem that is difficult to treat, especially in the middle-aged and elderly. It develops when bacteria indigenous to the oral cavity colonize gingival sulci, forming bacterial plaques in the absence of oral hygiene. Inflammation (gingivitis) develops and eventually spreads, causing tooth attachment loss (periodontitis). The diversity of the oral flora, the chronic nature of the disease, and the absence of a generally accepted animal or in vitro model, have made the molecular pathogenesis of this disease by bacteria difficult to study [1]. Therapies for this disease have also been hampered by ignorance of the bacterial induction process [2]. Current therapy requires that the dentist improve oral hygiene by debridement (scaling and root-planing) and repair tissue architecture using periodontal surgery as necessary [3]. The patient must undertake regular toothbrushing and flossing [4,5]. This therapy is expensive, time-consuming and unpredictable in its outcome [6]. Gingivitis is detected when the gingival sulcus, a shallow crevice between the teeth and gingiva, bleeds on gentle probing [7]. Bacterial plaques extend into this sulcus by an orderly process of colonization and coaggregation in the absence of oral hygiene [8-10]. The initial plaque is mostly composed of actinomyces and viridans streptococci, but it is soon overgrown by Gram-negative bacteria and spirochetes [8,11]. One of the earliest bacterial complexes that overgrow the initial flora in gingival sulci consists of E. corrodens and Capnocytophaga spp. These Gram-negative bacteria are found equally in sulci that are both healthy and inflamed, whereas different bacterial complexes are found exclusively at inflamed sulci and in association with uncontrolled periodontitis [12]. Many of these disease-associated bacteria are thought to induce inflammation by making short-chain
Patents 83
fatty acids that inhibit cell growth in culture [13,14]. A key observation is that the colonization by indigenous bacteria is required before the disease-associated flora appears in a sulcus. The number of inflamed sulci increases until, by 21 days of no oral hygiene, gingivitis is apparent throughout the mouth [11]. Eventually, the tooth attachment recedes beneath the cemental-enamel junction, forming periodontal pockets or causing gingival recession [15]. Saline extracts of bacterial plaques contain toxic proteins and short chain fatty acids that inhibit mammalian cell growth in culture [2022]. The short chain fatty acid content indicates the presence of disease-associated bacteria in the samples. The toxic proteins were identified with plaque toxinneutralizing monoclonal antibodies [23] and found to cross-react with a toxic 80 kilodalton protein (p80) from E. corrodens [24]. This protein is homologous to lysine decarboxylases from enteric bacteria [25], enzymes that metabolize extracellular lysine into cadaverine and carbon dioxide [26]. The inventor has found that this enzyme inhibits mammalian cell growth by depleting the culture medium of lysine, an amino acid which is not synthesized de novo by mammalian cells.

is for topical application in the form of an aqueous gel in the treatment of periodontal diseases including gingivitis, stomatitis, Apthous ulcers and post-extraction infection. Excerpt(s): The present invention relates to the pharmaceutical dental formulation for topical application in the form of aqueous gel suitable for the treatment of periodontal diseases which mainly include gingivitis, stomatitis, apthous ulcers, post extraction infections. The periodontal disease as used herein is a broad term used to describe those diseases which attack the gingiva and the underlying alveolar bone supporting the teeth. Two common periodontal diseases are gingivitis (inflammation of the gingiva) and periodontitis manifested by progressive resorption of alveolar bone, increasing mobility of the teeth and loss of the teeth at advanced stage). Periodontal disease is characterised by one or more of the following inflammation of the gingiva, formation of periodontal pockets bleeding and/or pus discharge from the periodontal pockets, resorption of alveolar bone, loose teeth and loss of teeth. This disease is generally considered to be caused by/associated with bacteria which are generally present in dental plaque which forms on the surface of the teeth and in periodontal pocket. Inflammation of the soft tissues (gingivae) around teeth is referred to as gingivitis and may be caused by microbial infection. In the case of progressive infection, direct microbial actions as well as the production of tissue-destructive enzymes such as collagenase, with or without stimulation of host tissue-destructive enzyme activity by the infectious agents can lead to destruction of supporting tissues around the teeth, a condition referred to as periodontitis (Klausen et al, 1991). The subgingival microbiota associated with these peridental conditions may be comprised of multiple species and may change during the course and progression of the dental infections. Gram (-ve) anaerobic bacteria in particular, are known to play an essential role. Streptococcus mutans: Aerobic. Synthesizes dextran. Colony density on tooth surface plaque rises to >50% in presence of high dietary sucrose. Able to produce acid from most sugars. The most important organism in the aetiology of dental caries.

Testkit and method Inventor(s): Blomlof; Leif (Lindingo, SE), Lindskog; Sven (Stockholm, SE), Zetterstrom; Olle (Jarfalla, SE) Assignee(s): Peridoc AB (Stockholm, SE) Patent Number: 6,340,455 Date filed: June 23, 1999 Abstract: Skin prick test for the determination of the predisposition of an individual to develop marginal periodontitis, said kit comprising: (a) a first reagent containing a known quantity of a surface structure common to anaerobic Gram negative pathogens which is capable of triggering the inflammatory response associated with periodontitis and gingivitis; (b) second reagent containing an agonist to said individual; (c) a negative control; and (d) instructions for the use of said kit; and a method for such determination of predisposition. Excerpt(s): The present invention relates to a skin prick test kit for the determination of the predisposition of an individual to develop marginal periodontitis. The invention also involves a method for the determination of such predisposition. The most frequent disease that affects the attachment apparatus of the teeth or the periodontium is gingivitis. It is caused by our indigenous bacterial flora and is, for some individuals a
86
Gingivitis
first step towards marginal periodontitis. A shift towards more anaerobic bacteria in the bacterial plaque is thought to be the reason why gingivitis turns into marginal periodontitis. Despite the fact that almost all individuals suffer from gingivitis, there is no clear relation between the degree of gingivitis and development of marginal periodontitis. Epidemiological studies have, however, shown that between 5 and 10% of the adult population develop severe marginal periodontitis, while a moderate form affects 50 to 80%. Progression of periodontitis is influenced by a multitude of modifying factors (Genco, RJ, Loe H. The role of systemic conditions and disorders in periodontal disease. Periodontol 2000 1994; 2: 98-116). These can be divided into systemic factors which affect the entire dentition and local factors which affect a single tooth or tooth surface.

Treatment of inflammation with 2,4,6-trihydroxy-alpha-rhomethoxyphenylacetophenone, or its pharmaceutically acceptable derivatives Inventor(s): Malaviya; Ravi (St. Paul, MN), Uckun; Fatih M. (White Bear Lake, MN) Assignee(s): Parker Hughes Institute (Roseville, MN) Patent Number: 6,248,790 Date filed: June 29, 2000 Abstract: 2,4,6-trihydroxy-.alpha.-p-methoxyphenylacetophenone (also identified herein as "D-58"), or its pharmaceutically acceptable derivatives such as salt and ester forms, is administered for inhibiting inflammatory reactions. The treatment can be remedial or prophylactic. Examples of the conditions that can be treated include acute inflammatory reactions and allergic inflammatory reactions, and specific examples include allergy, asthma, arthritis, psoriasis, skin sunburn, inflammatory pelvic disease, inflammatory bowel disease, urethritis, uvitis, senusitis, pneumonitis, encephalitis, meningitis, myocarditis, nephritis, osteomyelitis, myositis, hepatitis, gastritis, enteritis, dermatitis, gingivitis, appendicitis, pancreatitis, cholocystitis and cholangitis. The 2,4,6-trihydroxy.alpha.-p-methoxyphenylacetophenone can be administered by various routes as needed. Excerpt(s): The present invention is directed to the treatment of acute and chronic inflammatory responses, for example resulting from the presence of an allergen, injury, infection, etc. Allergic and acute inflammatory responses to injury, infection, or other tissue damage can set into motion a complex series of events. A variety of host cells that guard the host environment interface, including macrophages, mast cells, and epithelial/epidermal cells serve as the initiators of the inflammatory responses. These cells release various mediators during an inflammatory response, which include histamine, prostaglandins (PGs), leukotrienes (LTs) and proinflammatory cytokines (refs 1-4). These mediators have been implicated in the pathogenesis of a number of acute and chronic inflammatory conditions such as allergy, asthma, arthritis, psoriasis, and skin sunburn (refs 3-5). The release of inflammatory agents is mediated by a cascade of intracellular signaling events which include activation of phosphoinositide turnover (ref 6), increase in cAMP levels (ref 7), activation of protein kinase C, and an increase in intracellular calcium levels and tyrosine phosphorylation of several cytosolic proteins (refs 7 and 8). Considerable efforts have been made for identification of chemical compounds that can interrupt these signaling events as potential anti-inflammatory agents (refs 9-12). However, the need for agents providing improved inhibition continues. In accordance with the present invention, 2,4,6-trihydroxy-.alpha.-p-

E.sub.h raising compound distributed in an oral vehicle. The present invention is further directed to a method of inhibiting the formation of anionic sulfur species in the oral cavity and preventing a lowering of the E.sub.h of the oral cavity. A method of simultaneously reducing oral malodor, gingivitis and periodontitis by preventing or reducing oral putrefaction is also provided by this invention. The hard and soft tissues of the mouth are covered with microbial populations that contain bacteria with different metabolic capabilities. The Gram-positive bacteria within these microbial populations readily catabolize carbohydrates to produce acids which attack the hard tissues of the oral cavity, resulting in the formation of dental caries lesions (cavities). In contrast, the Gram-negative bacteria, especially the anaerobes readily metabolize various amino acids contained in salivary (and to lesser extent other) peptides and proteins in the oral cavity to form end-products which favor the formation of oral malodor and periodontitis. This process of peptide, protein and amino acid degradation by the mouth bacteria is referred to as oral bacterial putrefaction. The mixture of malodorous compounds produced by the Gram-negative anaerobic bacteria during putrefactive degradation of proteins, peptides and amino acids include hydrogen sulfide, methyl mercaptan, and dimethyl sulfide (formed from the sulfur containing amino acids cysteine, cystine and methionine); indole and skatole (formed during the metabolism of tryptophan); cadaverine and putrescine (produced from lysine and ornithine); and butyrate and valerate (produced from the metabolism of other amino acids). The production of these malodorous compounds in the oral cavity results in a condition commonly referred to as oral malodor. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Cyclodextrins in dental products Inventor(s): Nelson, Dennis G.A.; (New York, NY), Sheehan, Craig J.; (New York, NY) Correspondence: Paul H.

Excerpt(s): This non-provisional application is based upon and claims priority from Provisional Application No. 60/016,135 filed Apr. 24, 1996. The present invention relates to dental products comprising cyclodextrins. Dental plaque is present to some degree, in the form of a film, on virtually all dental surfaces. It is a by-product of microbial growth, and comprises a dense microbial layer consisting of a mass of micro-organisms embedded in a polysaccharide matrix. The micro-organisms present in plaque are mainly coccoidal organisms, particularly in early plaque. As plaque ages and matures, gram negative anaerobes and filamentous organisms appear and become more common after a few days. Plaque itself adheres to dental surfaces and may not be removed completely even with a rigorous brushing regimen and can build up, for example, in

The films include a water soluble film-forming polymer such as pullulan. Edible films are disclosed that include pullulan and antimicrobially effective amounts of the essential oils thymol, methyl salicylate, eucalyptol and menthol. The edible films are effective at killing the plaque-producing germs that cause dental plaque, gingivitis and bad breath. The film can also contain pharmaceutically active agents. Methods for producing the films are also disclosed. Excerpt(s): This invention relates to fast dissolving orally consumable films. The films are used to deliver breath deodorizing agents, antimicrobial agents and salivary stimulants to the oral cavity. The films can also be used to deliver pharmaceutically active agents. In a more perfect world, people would thoroughly cleanse their mouths after each meal as part of their routine oral hygienic practices. Unfortunately, several factors conspire to prevent widespread compliance with this basic requirement of a good oral cleaning regimen. Oral cleansing can be difficult or inconvenient at times, depending on the nature of the cleansing and the situation in which the cleansing must occur. Brushing, flossing, cleaning your tongue and gargling using a variety of devices and compositions well-suited for the privacy of one's home are common oral care practices. However, the devices and compositions used in oral cleansing practices are less convenient to use away from home, where bathroom facilities might be scarce, unavailable or unsanitary.

Excerpt(s): This application claims priority to U.S. Provisional Patent Application No. 60/297,875 filed Jun. 13, 2001. The present inventions are generally in the fields of pharmaceutically active lactones, their pharmaceutical formulations, and method of use thereof, and methods for the synthetic preparation of chemically functionalized lactones useful therefor as anticancer and antiinfective agents. Despite the development of many different compounds which are useful in the treatment of infection, cancer, and other disorders, there remains a need for the development of new compounds which may be effective at lower dosages, more selective, having fewer side effects or capable of treating diseases or disorders where resistance to the known compounds has developed. Chemotherapeutic agents are used for the treatment of infections, cancer, abnormal proliferation disorders (endometriosis, restenosis, psoriasis), and other disorders. Most chemotherapeutic agents have side effects due to lack of specificity. For example, cancer is one of the leading causes of death. One of the primary modes of treating cancer, chemotherapy, is used specifically to limit cell growth and replication. Most chemotherapy agents also affect neoplastic and rapid proliferating cells of normal tissues (e.g., bone marrow, hair follicles, etc.), which results in several negative side effects including hair loss, nausea, vomiting, and suppression of bone marrow function. Moreover, effectiveness of these agents frequently diminishes over time due to the development of resistance. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Bioactive glasses have been tested as substitutes for reconstruction of defects of the facial bones (1), rehabilitation of the dentoalveolar complex (2), regeneration of periodontal pockets (3), and recently also for treatment of hypersensitive teeth (4). The surface reactive bioactive glass contains SiO.sub.2, Na.sub.2O, CaO and P.sub.2O.sub.5. The chemical bond with bone in vivo is reported to result from the leaching of Na.sup.+-ions and the congruent dissolution of calcium, phosphate and silica from the glass in an aqueous environment, giving rise to an Si-rich layer on the material. The Si-rich layer acts as a templet for a calcium phosphate precipitation, which then binds to the bone (5). Bioactive glass has been successfully used for reconstructions of closed bone defects, which are not exposed to the external environment after the clinical procedure (1). However, there are a number of conditions for which bioactive glasses are used as therapeutic materials but that, at the same time, are imminently prone to microbial infections. These include clinical conditions such as infected frontal sinuses (6), periodontal pockets (3) and hypersensitive teeth as a complication of periodontal treatment or tooth wear that has resulted in the exposure of dentin and dentinal tubules (4). Obviously, the demonstration of any antibacterial activity of the biactive glass would add to the therapeutic value of the material in the clinical conditions described. Earlier studies have shown that P. gingivalis is agglutinated in the presence of granules (315-500.mu.m) of the bioactive glass S53P4 in an aqueous environment due to Ca.sup.+2-ions released from the granules (19, 7). The minimum Ca.sup.2+concentration needed to induce agglutination of P. gingivalis was found to be 0.04 g/l (7). In these studies, however, no reduction of the viability of the bacteria was noticed.

Novel lactic acid bacteria Inventor(s): Oh, Jong Suk; (Kwangju-City, KR) Correspondence: Frommer Lawrence & Haug; 745 Fifth Avenue- 10th FL.; New York; NY; 10151; US Patent Application Number: 20030077814 Date filed: April 15, 2002 Abstract: Enterococcus spp. 1357, Lactobacillus spp. V20 and Lactococcus spp. 1370, and H.sub.2O.sub.2-producing Streptococci have a potent and lasting inhibitory activity on the production of water-insoluble glucan (mutan) and dental plaque in human mouth,

or the growth of anaerobic bacteria causing gingivitis, periodontitis, and accompanied halitosis. Excerpt(s): The present invention relates to some novel lactic acid bacteria which inhibit the production of dental plaque in human mouths. More specifically, the production of water-insoluble glucan (mutan), a major component of dental plaque, which is produced by bacteria normally inhibiting in human mouths, can be inhibited by the novel bacteria. Oral anaerobic bacteria causing gingivitis, periodontitis, and accompanied halitosis (malodor) can be inhibited by the novel bacteria, too. These lactic acid bacteria belong to Enterococcus spp., Lactobacillus spp., Lactococcus spp., and Stretococcus spp. which inhibit the production of water-insoluble glucan or antagonize against the bacteria playing a role in forming water-insoluble glucan, or inhibit the growth of anaerobic bacteria causing gingivitis and periodontitis. Lactic acid bacteria generally ferment carbohydrates to lactic acid. Lactic acid bacteria live in the oral cavities and the alimentary tracts of men and animals and are utilized for the manufacture of fermentative foods, such as yogurt, cheese, etc. In addition, they are used for the production of biologically active materials, such as medicines. Representatives of these lactic acid-producing bacteria are Streptococcus thermophilus, Enterococcus faecalis, Enterococcus durans, Lactococcus lactis, Lactobacillus acidophilus, Lactobacillus bulgaricus, Lactobacillus casei, and Lactobacillus plantarum. As inhabitants in the entrails of men and animals, these Gram-positive lactic acid bacteria are known to play an important role in maintaining the entrails healthy by the production of lactic acid and antibacterial materials which inhibit the growth of pathogenic bacteria. The most important component of dental plaque is glucan. Glucan is either water-soluble glucan, dextran having 1,6-.alpha. linkage as a predominant linkage, or water-insoluble glucan (mutan) having 1,3-.alpha. linkage as a predominant linkage. The solubility in water is inversely proportional to the number of 1,3-.alpha. linkage. Therefore, water-insoluble glucan (mutan) serves as a main matrix of dental plaque. Dextranase (.alpha.-1,6 glucan hydrolase) which digests dextran, was tested as to its ability to prevent dental plaque. But the effectiveness value of dextranse to prevent dental plaque was questionable (Essential Dental Microbiology: Appleton & Lange, Norwalk, San Mateo, p.337, 1991), because dextranase can not digest mutan, the main matrix of dental plaque. Mutanase (endo-.alpha.-1,3-glucanase) which decomposes mutan was found to have some effect on the digestion of dental plaque. The decomposition effect of the mutanase on dental plaque, however, was trivial and it took too much time to express its effectivity. Therefore, these enzymes were found to have an insignificant effect on dental plaque formation in human oral cavity. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Operatory water disinfection system Inventor(s): Burris, William A.; (Pittsford, NY), Prinsen, Phillip M.; (Ontario, NY) Correspondence: Steven R. Scott; Eugene S. Stephens & Associates; 56 Windsor Street; Rochester; NY; 14605; US Patent Application Number: 20020134736 Date filed: February 13, 2002 Abstract: This ozone appliance for the professional dental office and other medical applications introduces dissolved ozone into dental and surgical operatory water lines. This dissolved ozone can not only disinfect water and water lines; it can also reduce gum bleeding, gingivitis, bad breath, teeth stains and oral bacteria. Additionally, it can

aid in wound disinfection in surgery and attack microbial contamination of water from dental and surgical operatory water lines and attached hand pieces and dispensing devices by automatically killing waterborne germs and destroying biofilms where germs can hide and grow. It can, therefore, be used to disinfect water lines in dental operations and for other medical applications such as providing liquid containing ozone for cleaning and disinfecting skin prior to surgery (and tissue exposed during surgery). Further, a unit connected to operatory water lines can give an audible or other alarm if the water becomes unsafe. Excerpt(s): This application claims the benefit of U.S. Provisional Application No. 60/269,403, filed on Feb. 16, 2001, which provisional application is incorporated by reference herein. Ozone disinfection of operatory water lines, in particular dental operatory unit water lines. There has been serious concern that microbial contamination of dental office water systems puts dental patients at risk of diseases. The problem of water contamination, especially when due to cross contamination from other patients, is greatest for patients with weak immune systems. Additionally, dental water can become contaminated from the water supply. More commonly, contamination results from growth of microbial biofilms on the inner surface of water lines. Such biofilms can include germs introduced from patients. Germs can slough off from biofilms as water passes through water lines. Thus, it is not uncommon for water coming out of dental hand pieces to have more than one million bacteria per milliliter while the water entering the dental lines has less than 100 bacteria per milliliter.

Oral care compositions comprising chlorite and methods Inventor(s): Wimalasena, Rohan Lalith; (Liberty Township, OH), Witt, Jonathan James; (Cincinnati, OH), Wong, Andrew Lee; (West Chester, OH) Correspondence: Emelyn L. Hiland; The Procter & Gamble Company; Health Care Research Center (box 1050); P.O. Box 8006; Mason; OH; 45040-8006; US Patent Application Number: 20010006624 Date filed: January 30, 2001 Abstract: The present invention relates to oral care compositions, including therapeutic rinses, especially mouth rinses, as well as toothpastes, gels, tooth powders, chewing gums, mouth sprays, and lozenges (including breath mints), comprising at least a minimally effective amount of chlorite ion, wherein preferably the pH of the final composition is greater than 7 and level of chlorine dioxide or chlorous acid is less than about 50 ppm, preferably is essentially free of chlorine dioxide or chlorous acid. This invention fuirther relates to a method for treating or preventing gingivitis, plaque, periodontal disease, and/or breath malodor, and/or for the whitening of teeth, in humans or other animals, by applying a safe and effective amount of the chlorite ion composition to the oral cavity. Excerpt(s): The present invention relates to oral care compositions, including therapeutic rinses, especially mouth rinses, as well as toothpastes, tooth gels, tooth powders, chewing gums, mouth sprays, and lozenges (including breath mints), comprising an effective amount of chlorite ion. This invention further relates to a method for treating or preventing conditions of the oral cavity, such as gingivitis, plaque, periodontal disease, and/or breath malodor, as well as to a method for whitening teeth, in humans or other animals. Oral malodor, plaque, gingivitis, periodontal disease, and
Patents 95
discoloration of the teeth, are all undesirable conditions that affect many people. First malodor of the oral cavity is also known as halitosis or bad breath. It is broadly estimated in the US. that 20-90 million individuals have oral malodor. It is generally believed that the cause of this condition is due to the presence of anaerobic bacteria, especially gram-negative anaerobic bacteria, in the mouth. These bacteria will generate volatile sulfur compounds (VSC) which are known to cause breath malodor. It is recognized in the art that some breath malodor is caused by three chemical compounds. Specifically, these compounds are hydrogen sulfide (H--S--H), methyl mercaptan (CH.sub.3--S--H) and dimethyl sulfide (CH.sub.2--S--CH.sub.3). These compounds result from the degradation of epithelial cells and bacteria in the oral cavity. Specifically, the polypeptide chains of the epithelial cell walls, are composed of a series of amino acids including cysteine and methionine which contain sulfur side chains. The death of microorganisms or epithelial cells results in degradation of the polypeptide chains into their amino acid components, especially cysteine and methionine. Cysteine and methionine are precursors to the formation of VSC. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Oral composition containing NSAIDs and essential oils Inventor(s): Pan, Pauline; (Morris Plains, NJ), Rubin, Michael; (Boonton, NJ), Volpe, Frank; (Kinnelon, NJ) Correspondence: Evan J. Federman; Legal Division; Warner-lambert Company; 201 Tabor Road; Morris Plains; NJ; 07950; US Patent Application Number: 20010049363 Date filed: January 16, 2001 Abstract: Oral compositions for treating and/or preventing gingivitis are provided. The compositions include at least one NSAID, thymol, methyl salicylate, menthol and eucalyptol. The NSAID, thymol, methyl salicylate, menthol and eucalyptol are present in the composition in synergistically effective amounts. The compositions can be provided in the form of, e.g., mouthwashes or toothpastes, and are not only effective against gingivitis, but can also prevent or treat halitosis and other detrimental conditions of the oral cavity. Excerpt(s): This invention relates to oral compositions for treating and/or preventing diseases of the mouth, and more particularly to oral compositions for treating and/or preventing gingivitis. Gingivitis is a disease characterized by inflammation of the gingiva or gums. It is generally accepted that this inflammation is typically caused by an overabundance of bacterial plaque about the base of the teeth. Thus, a good deal of research has focused on preventing or treating gingivitis by minimizing the amount of bacterial plaque on the teeth and countering the inflammatory response of the gingiva. The amount of bacterial plaque on the teeth can be controlled by good hygiene, including mechanical removal by frequent brushing, flossing and the like. As an adjunct to the traditional mechanical methods for limiting the amount of bacterial plaque on the teeth, chemical methods have been developed that typically function by killing the bacteria responsible for forming plaque on the teeth.

Ozone irrigator Inventor(s): Burris, W. Alan; (Pittsford, NY), Prinsen, Phillip M.; (Ontario, NY) Correspondence: Steven R. Scott; Eugene S. Stephens & Associates; 56 Windsor Street; Rochester; NY; 14605; US Patent Application Number: 20020094309 Date filed: January 9, 2002 Abstract: This portable appliance can be used to clean teeth by liquid (water or solution) containing dissolved ozone, which is a potent oxidizer and germ killer. Preferably, its cleaning action is enhanced by pulsations of the liquid stream. The dissolved ozone can reduce or eliminate gingivitis, gum bleeding, bad breath, teeth stains, and harmful oral bacteria. This appliance can also be used for nasal irrigation for sinusitis treatment and for ear irrigation, eye care, and general cleaning. Additionally, since its output pump is independent of the ozone dissolving system, the ozone dissolving system can be configured as an add on device for an oral irrigator such as a Water Pik.TM. manufactured by WaterPik Technologies, Inc. In this configuration, the ozonated liquid is delivered by either gravity or pumped flow, to the original reservoir connection with the irrigator serving as the delivery portion of this invention. Excerpt(s): This application claims the benefit of U.S. Provisional Application No. 60/261,415, filed on Jan. 12, 2001, which provisional application is incorporated by reference herein. Our invention pertains generally to ozone generators used for the creation of ozonated fluids. It can be used for a variety of purposes, including oral irrigation devices primarily for home use. By this invention, we have improved upon the portable oral irrigation device. WaterPik.TM. is a well-known trade name belonging to WaterPik Technologies, Inc. The WaterPik.TM. is an example of the type of consumer appliance we are improving. By dissolving ozone in the liquid and removing the undissolved gas from the dispensed liquid, we are able to deliver a potent oxidizing liquid to the oral cavity. The benefits of oxidation are known and will be detailed in the summary of the invention. We believe the addition of dissolved ozone to an oral irrigant to be a significant and beneficial improvement to oral irrigators without dissolved ozone. We also believe dissolved ozone to be much more effective at oxidizing oral bacteria than undissolved ozone gas transported to a point of desired disinfection. It also should be noted that an ozone-containing gas potent enough to cause disinfection is known to be offensive to the sense of smell.

Most tissues exist in a highly regulated dynamic equilibrium wherein new tissue is formed and existing tissue is degraded and eliminated. The degradation of the extracellular matrix (ECM), including connective tissue and basement membranes, is effected by the metalloproteinases which are released from connective tissue and invading inflammatory cells. There are at least for distinct groups of the more than 20 matrix metalloproteinases (MMP) which have been identified (Birkedal-Hansen, H. J. Oral Pathol. 1988 17:445; Birkedal-Hansen, H. Curr. Opin.

Excessive unregulated activity of these enzymes can result in undesirable tissue destruction and their activity is regulated at the transcription level, by controlled activation of the latent proenzyme and, after translation, by intracellular specific inhibitory factors such as TIMP ("Tissue Inhibitors of MetalloProteinase") or by more general proteinase inhibitors such as.alpha.2macroglobulins. Inhibitors of MMPs also have been found to inhibit the release of the pleiotropic proinflammatory cytokine, tumor necrosis factor alpha which has be associated with the pathogenesis of numerous inflammatory, autoimmune, and neoplastic diseases. The protease, TNF.alpha.-Converting Enzyme (TACE), catalyzes the release of TNF.alpha. from a membrane bound precursor protein. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Gingivitis
Excerpt(s): This invention relates in general to heterocycleketohydrazide protease inhibitors, particularly such inhibitors of cysteine and serine proteases, more particularly compounds which inhibit cysteine proteases, even more particularly compounds which inhibit cysteine proteases of the papain superfamily, yet more particularly compounds which inhibit cysteine proteases of the cathepsin family, most particularly compounds which inhibit cathepsin K. Such compounds are particularly useful for treating diseases in which cysteine proteases are implicated, especially diseases of excessive bone or cartilage loss, e.g., osteoporosis, periodontitis, and arthritis. Bone is composed of a protein matrix in which spindle- or plate-shaped crystals of hydroxyapatite are incorporated. Type I Collagen represents the major structural protein of bone comprising approximately 90% of the structural protein. The remaining 10% of matrix is composed of a number of non-collagenous proteins, including osteocalcin, proteoglycans, osteopontin, osteonectin, thrombospondin, fibronectin, and bone sialoprotein. Skeletal bone undergoes remodeling at discrete foci throughout life. These foci, or remodeling units, undergo a cycle consisting of a bone resorption phase followed by a phase of bone replacement. Bone resorption is carried out by osteoclasts, which are multinuclear cells of hematopoietic lineage. The osteoclasts adhere to the bone surface and form a tight sealing zone, followed by extensive membrane ruffling on their apical (i.e., resorbing) surface. This creates an enclosed extracellular compartment on the bone surface that is acidified by proton pumps in the ruffled membrane, and into which the osteoclast secretes proteolytic enzymes. The low pH of the compartment dissolves hydroxyapatite crystals at the bone surface, while the proteolytic enzymes digest the protein matrix. In this way, a resorption lacuna, or pit, is formed. At the end of this phase of the cycle, osteoblasts lay down a new protein matrix that is subsequently mineralized. In several disease states, such as osteoporosis and Paget's disease, the normal balance between bone resorption and formation is disrupted, and there is a net loss of bone at each cycle. Ultimately, this leads to weakening of the bone and may result in increased fracture risk with minimal trauma. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Pullulan free edible film compositions and methods of making the same Inventor(s): Barkalow, David G.; (Deerfield, IL), Chapdelaine, Albert H.; (Naperville, IL), Dzija, Michael R.; (LaGrange Park, IL) Correspondence: Robert M. Barrett; Bell, Boyd & Lloyd; P.O. Box 1135; Chicago; IL; 60690-1135; US Patent Application Number: 20020131990 Date filed: November 8, 2001 Abstract: Improved and inexpensive pullulan free edible film formulations and methods for making the same are provided. The edible pullulan free film compositions comprise effective amounts of at least one film forming agent; at least one bulk filler agent; at least one plasticizing agent; and optionally at least one thickening agent. Medicaments and other additive agents can also be incorporated into the edible films. The present invention further provides methods of delivering a medicament, treating halitosis, treating xerostomia, and treating plaque or gingivitis using the pullulan free edible film compositions. Excerpt(s): The present invention generally relates to edible films. More specifically, the present invention relates to pullulan free edible film compositions and methods of making the same. Oral cleansing and breath freshening may be difficult or inconvenient at times, depending on the nature of the breath freshening desired and the situation in which the breath freshening must occur. Brushing, flossing, cleaning your tongue and gargling using a variety of devices and compositions are common oral care practices well-suited for the privacy of one's home. However, such devices and compositions are less convenient to use away from the home where bathroom facilities might be scarce, unavailable or unsanitary. However, less obtrusive oral products have been developed. These include breath-freshening gums, lozenges, mouth sprays, and edible films. Many thin edible films are made of pullulan, which may be used to deliver medicaments or other agents such as flavors and sweeteners to the oral cavity. However, pullulan is an expensive ingredient to use in the manufacture of such edible films because it has limited availability within the film formulation industry. Other edible materials such as modified starches and cellulosics have been employed as a replacement for pullulan within edible film compositions. Unfortunately, such materials typically lack one or

Therapeutic and cosmetic actives in compositions comprising polybutene inhibit or prevent gingivitis, caries, staining, fungi, bacteria and plaque build-up in the oral cavity by means of the delivery system. Excerpt(s): This application claims the benefit of U.S. Provisional Application No. 60/276,977, filed March 19, 2001. The present invention relates to systems for delivering cosmetic and therapeutic benefits to the oral cavity by applying low molecular weight polybutene to the teeth by means of an integral carrier, in one embodiment, a strip of material. Dental products by which various cosmetic and/or therapeutic actives are delivered to teeth and oral cavity have been previously known. Examples of such products include: brushing aids such as dentifrice products for delivery of anti-caries actives like fluoride; effervescent denture cleansing tablets, which require the artificial teeth to soak for a period of time, to remove plaque and debris; and mouthwashes containing breath fresheners or antibacterial actives. However, such conventional dental care products typically do not maintain actives in the oral cavity long enough to optimally enhance or prolong their therapeutic, prophylactic and/or cosmetic benefits.

thereof;b) about 0.01 weight % to about 5 weight % of a phenolic, said phenolic selected from the group consisting of menthol, eucalyptol, methyl salicylate, thymol, triclosan, and mixtures thereof; andc) an orally acceptable carrier.The claimed composition is useful in retarding the development of plaque, treating gingivitis, and reducing the viable population of micro-organisms in the oral cavity of a mammal.This nonprovisional application is based upon and claims priority from Provisional Application No. 60/042,874 filed Mar. 31, 1997 Excerpt(s): The present invention relates to oral care products comprising citrus-masked phenolics Oral compositions including mouthwashes and dentifrices containing phenolic compounds have been formulated using one or more of the following: menthol, methyl salicylate, eucalyptol and thymol are well known (U.S. Pat. No. 4,945,087; PCT Int. Appl. Nos. WO 94 16,674; WO 94 07,477; WO 94 18,939). These compositions are characterized by their relatively high alcohol levels (20-27 volume %) which causes them to have negative aesthetics, including excessive "bite" and "burn". These compositions often have an unpleasant medicinal taste which can be unattractive to consumers. In particular, thymol is the ingredient which contributes most to the unpleasant, medicinal and harsh taste of these compositions although the combination of several phenolics imparts greater negative taste attributes to these compositions than any one phenolic by itself. Triclosan (2, 4, 4'-trichloro-2'-hydroxydiphenyl ether) is a phenolic, nonionic antimicrobial agent used in various soap and toiletry products. In the oral care area, triclosan has been used as a plaque-inhibitory agent in various toothpastes and mouthrinses. Triclosan can have an unpleasant, medicinal taste and at sufficient concentration can cause numbing of the tongue and other mucosal and gingival tissues. Citrus-flavored mouthwashes or dentifrices have been formulated, as well as methods for preparing clear citrus-flavored mouthwashes including for example, U.S. Pat. Nos. 3,876,759 and 4,420,471.

Treatment of inflammation with 2,4,6-trihydroxy-alpha-para-methoxyphenylacetophenone, or its pharmaceutically acceptable derivatives Inventor(s): Malaviya, Ravi; (St. Paul, MN), Uckun, Fatih M.; (White Bear Lake, MN) Correspondence: Merchant & Gould PC; P.O. Box 2903; Minneapolis; MN; 55402-0903; US Patent Application Number: 20020010217 Date filed: June 19, 2001 Abstract: 2,4,6-trihydroxy-.alpha.-p-methoxyphenylacetophenone (also identified herein as "D-58"), or its pharmaceutically acceptable derivatives such as salt and ester forms, is administered for inhibiting inflammatory reactions. The treatment can be remedial or prophylactic. Examples of the conditions that can be treated include acute inflammatory reactions and allergic inflammatory reactions, and specific examples include allergy, asthma, arthritis, psoriasis, skin sunburn, inflammatory pelvic disease, inflammatory bowel disease, urethritis, uvitis, senusitis, pneumonitis, encephalitis, meningitis, myocarditis, nephritis, osteomyelitis, myositis, hepatitis, gastritis, enteritis, dermatitis, gingivitis, appendicitis, pancreatitis, cholocystitis and cholangitis. The 2,4,6-trihydroxy.alpha.-p-methoxyphenylacetophenone can be administered by various routes as needed. Excerpt(s): The present invention is directed to the treatment of acute and chronic inflammatory responses, for example resulting from the presence of an allergen, injury, infection, etc. Allergic and acute inflammatory responses to injury, infection, or other tissue damage can set into motion a complex series of events. A variety of host cells that guard the host environment interface, including macrophages, mast cells, and epithelial epidermal cells serve as the initiators of the inflammatory responses. These cells release various mediators during an inflammatory response, which include histamine, prostaglandins (PGs), leukotrienes (LTs) and proinflammatory cytokines (refs 1-4). These mediators have been implicated in the pathogenesis of a number of acute and chronic inflammatory conditions such as allergy, asthma, arthritis, psoriasis, and skin sunburn (refs 3-5). The release of inflammatory agents is mediated by a cascade of intracellular signaling events which include activation of phosphoinositide turnover (ref 6), increase in cAMP levels (ref 7), activation of protein kinase C, and an increase in intracellular calcium levels and tyrosine phosphorylation of several cytosolic proteins (refs 7 and 8). Considerable efforts have been made for identification of chemical compounds that can interrupt these signaling events as potential anti-inflammatory agents (refs 9-12). However, the need for agents providing improved inhibition continues. In accordance with the present invention, 2,4,6-trihydroxy-.alpha.-- pmethoxyphenylacetophenone (also identified herein as "D-58"), or its pharmaceutically acceptable derivatives such as salt and ester forms, is administered for inhibiting inflammatory reactions to a subject in need thereof. The treatment can be remedial or prophylactic. Examples of the conditions that can be treated include acute as well as chronic inflammatory reactions and allergic inflammatory reactions, and specific examples include allergy, asthma, arthritis, psoriasis, skin sunburn, inflammatory pelvic disease, inflammatory bowel disease, urethritis, uvitis, sinusitis, pneumonitis, encephalitis, meningitis, myocarditis, nephritis, osteomyelitis, myositis, hepatitis, gastritis, enteritis, dermatitis, gingivitis, appendicitis, pancreatitis, cholocystitis and cholangititis. The 2,4,6-trihydroxy-.alpha.-p-methoxyphenylacetophenone can be administered by one of a variety of routes as needed. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Microbiology of HIV-Associated Gingivitis and Periodontitis Source: Perspectives on Oral Manifestations of AIDS: Diagnosis and Management of HIV-Associated Infections. San Diego, CA, January 18-20, 1988. Contact: PSG Publishing Company, 545 Great Rd, Littleton, MA, 01460, (508) 486-8971. Summary: These proceedings of the Conference Perspectives on Oral Manifestations of AIDS: Diagnosis and Management of HIV-Associated Infections held in San Diego, CA, on January 18-20, 1988. They describes the investigation of microbiota associated with intraoral lesions associated with infection by the Human immunodeficiency virus (HIV) that causes Acquired immunodeficiency syndrome (AIDS). Subgingival plaque samples from HIV-seropositive males and from HIV-seronegative controls were examined by indirect immunofluorescence and microbiological culturing. Samples were classified as HIV-associated gingivitis, HIV-associated periodontitis, or disease-free in an HIVpositive person. Microbiological analysis revealed that HIV-gingivitis and HIV-
106 Gingivitis
periodontitis sites contained more Candida albicans compared with control sites. Also, Bacteroides gingivalis, B intermedius, Fusobacterium nucleatum, Actinobacillus actinomycetemcomitans, Eikenella Corrodens, and Wolinella were more prevalent in HIV-periodontitis sites and HIV-gingivitis sites than in HIV-positive healthy sites and control sites. Distribution of microbiota in HIV-periodontitis and HIV-gingivitis sites appeared similar to those found in classic periodontitis sites. The microbiota from HIVpositive healthy and HIV-negative control sites was characteristic of healthy periodontium. It is suggested that HIV-gingivitis may be a precursor to HIVperiodontitis.
Book Summaries: Online Booksellers Commercial Internet-based booksellers, such as Amazon.com and Barnes&Noble.com, offer summaries which have been supplied by each title’s publisher.

(800) 829-9045. Website: www.health.harvard.edu/newsletters/subinfo.html. Summary: Research conducted in recent decades has uncovered potential links between chronic gum infection and conditions as serious as diabetes, stroke, heart disease, and pregnancy complications. Also, oral diseases may contribute to malnutrition and create a variety of psychosocial difficulties, including low self-esteem and discrimination in work or social settings. This article, from a health newsletter, describes the new understanding of the relationship between oral health and general health. Topics include the pathology of dental decay, including plaque and the development of cavities (dental caries); periodontal disease, including gingivitis and periodontitis; and the fundamentals of toothbrushing and flossing, including the use of electric toothbrushes, different types of toothpaste, and mouthrinses. 2 figures.

Oral Health and Heart Disease Source: Harvard Health Letter. 11(7): 1-3. March 2001. Contact: Available from Harvard Health Publications. P.O. Box 420300, Palm Coast, FL 32142-0300. (800) 829-9045. Website: www.health.harvard.edu. Summary: This article explores the recent evidence that by averting gum disease, patients might actually be reducing their chances for developing heart disease. The author notes that, at the very least, it seems clear that people with worse dental health have a higher risk of heart attack. Recent findings link periodontal disease to cardiovascular disease. Periodontal disease is any disease, including gingivitis or periodontitis, that affects the gums and associated membranes. However, not all of these studies adequately controlled for other risk factors (for example, socioeconomic status, age, or unhealthy behaviors). Poor dental health may consequently have been an indication of poor personal hygiene or suboptimal health habits. The author cautions that the observed increase in heart disease risk among those with poor dental health may have reflected a general lack of health care, rather than a lack of dental care in particular. The article also reports on present Harvard studies that are evaluating the role of inflammation and diet as potential mediators. For example, periodontal disease and resulting tooth loss may lead to poor dietary habits that, in turn, might increase heart disease risk. The article concludes by hypothesizing the role of inflammation (the body's response to infection or injury) in heart disease. 1 figure.

[email protected]. Website: www.colgateprofessional.com (full-text available online). Summary: This article reminds dental hygienists of the effects of nutritional supplements on periodontal status. It has been shown that a large percentage of patients with gingivitis and periodontal disease are deficient in vitamins that are vital for the maintenance of healthy gingival (gum) tissues. This article briefly reports on a research study undertaken to assess whether nutritional supplements can aid in improving the oral health of patients with these conditions. Results after 60 days of nutritional supplements were suggestive but not conclusive. Comparison of the bleeding index (BI) between the two treatment groups indicated a 21 percent improvement for the nutritional supplements group, and a 14 percent improvement for the placebo group. One table lists various nutritional supplements with their proposed function. 1 table. 3 references. •

Written primarily for an audience of older adults, the article emphasizes that although aging can bring changes that make teeth more vulnerable, with proper care, the teeth can last a lifetime. Topics include dental plaque, gingivitis, periodontitis, dental risk factors associated with aging, and the adverse effects of medications (notably xerostomia, or dry mouth). The article concludes with a brief discussion of the risk factors for cavities and periodontal disease in older adults. These factors include co-existing medical conditions or systemic disease, a poor diet, lack of preventive dental care, lack of fluoridated water, and lack of transportation to dental care. One sidebar provides a brief quiz for readers to determine if they need a dental check-up. 1 figure.

CHAPTER 9. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for gingivitis. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a nonprofit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI® Advice for the Patient® can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with gingivitis. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The

staff.17 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.18 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
17
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 18 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on gingivitis can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to gingivitis. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to gingivitis. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “gingivitis”:

You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on gingivitis. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits. The following was recently posted in this archive: •

The National Guideline Clearinghouse™ The National Guideline Clearinghouse™ offers hundreds of evidence-based clinical practice guidelines published in the United States and other countries. You can search this site located at http://www.guideline.gov/ by using the keyword “gingivitis” (or synonyms). The following was recently posted: •
Parameter on plaque-induced gingivitis Source: American Academy of Periodontology - Professional Association; 1996 October (revised 2000 May); 2 pages http://www.guideline.gov/summary/summary.aspx?doc_id=2324&nbr=1550&a mp;string=gingivitis The NIH Search Utility
The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to gingivitis. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information. The following is a representative sample: •

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to gingivitis. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with gingivitis.

The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about gingivitis. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “gingivitis” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “gingivitis”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “gingivitis” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “gingivitis” (or a synonym) into the search box, and click “Submit Query.”

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.19
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

GINGIVITIS DICTIONARY The definitions below are derived from official public sources, including the National Institutes of Health [NIH] and the European Union [EU]. Abdominal: Having to do with the abdomen, which is the part of the body between the chest and the hips that contains the pancreas, stomach, intestines, liver, gallbladder, and other organs. [NIH] Abdominal Pain: Sensation of discomfort, distress, or agony in the abdominal region. [NIH] Acceptor: A substance which, while normally not oxidized by oxygen or reduced by hydrogen, can be oxidized or reduced in presence of a substance which is itself undergoing oxidation or reduction. [NIH] Acetylcholine: A neurotransmitter. Acetylcholine in vertebrates is the major transmitter at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system. It is generally not used as an administered drug because it is broken down very rapidly by cholinesterases, but it is useful in some ophthalmological applications. [NIH] Actinomyces: A genus of gram-positive, rod-shaped bacteria whose organisms are nonmotile. Filaments that may be present in certain species are either straight or wavy and may have swollen or clubbed heads. [NIH] Acute lymphoblastic leukemia: ALL. A quickly progressing disease in which too many immature white blood cells called lymphoblasts are found in the blood and bone marrow. Also called acute lymphocytic leukemia. [NIH] Acute lymphocytic leukemia: ALL. A quickly progressing disease in which too many immature white blood cells called lymphoblasts are found in the blood and bone marrow. Also called acute lymphoblastic leukemia. [NIH] Adaptability: Ability to develop some form of tolerance to conditions extremely different from those under which a living organism evolved. [NIH] Adjustment: The dynamic process wherein the thoughts, feelings, behavior, and biophysiological mechanisms of the individual continually change to adjust to the environment. [NIH] Adrenal Medulla: The inner part of the adrenal gland; it synthesizes, stores and releases catecholamines. [NIH] Adrenergic: Activated by, characteristic of, or secreting epinephrine or substances with similar activity; the term is applied to those nerve fibres that liberate norepinephrine at a synapse when a nerve impulse passes, i.e., the sympathetic fibres. [EU] Adsorption: The condensation of gases, liquids, or dissolved substances on the surfaces of solids. It includes adsorptive phenomena of bacteria and viruses as well as of tissues treated with exogenous drugs and chemicals. [NIH] Adsorptive: It captures volatile compounds by binding them to agents such as activated carbon or adsorptive resins. [NIH] Adverse Effect: An unwanted side effect of treatment. [NIH] Aetiology: Study of the causes of disease. [EU] Affinity: 1. Inherent likeness or relationship. 2. A special attraction for a specific element, organ, or structure. 3. Chemical affinity; the force that binds atoms in molecules; the
146 Gingivitis
tendency of substances to combine by chemical reaction. 4. The strength of noncovalent chemical binding between two substances as measured by the dissociation constant of the complex. 5. In immunology, a thermodynamic expression of the strength of interaction between a single antigen-binding site and a single antigenic determinant (and thus of the stereochemical compatibility between them), most accurately applied to interactions among simple, uniform antigenic determinants such as haptens. Expressed as the association constant (K litres mole -1), which, owing to the heterogeneity of affinities in a population of antibody molecules of a given specificity, actually represents an average value (mean intrinsic association constant). 6. The reciprocal of the dissociation constant. [EU] Agar: A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis. [NIH]
Age of Onset: The age or period of life at which a disease or the initial symptoms or manifestations of a disease appear in an individual. [NIH] Aggravation: An increasing in seriousness or severity; an act or circumstance that intensifies, or makes worse. [EU] Agonist: In anatomy, a prime mover. In pharmacology, a drug that has affinity for and stimulates physiologic activity at cell receptors normally stimulated by naturally occurring substances. [EU] Albumin: 1. Any protein that is soluble in water and moderately concentrated salt solutions and is coagulable by heat. 2. Serum albumin; the major plasma protein (approximately 60 per cent of the total), which is responsible for much of the plasma colloidal osmotic pressure and serves as a transport protein carrying large organic anions, such as fatty acids, bilirubin, and many drugs, and also carrying certain hormones, such as cortisol and thyroxine, when their specific binding globulins are saturated. Albumin is synthesized in the liver. Low serum levels occur in protein malnutrition, active inflammation and serious hepatic and renal disease. [EU] Algorithms: A procedure consisting of a sequence of algebraic formulas and/or logical steps to calculate or determine a given task. [NIH] Alimentary: Pertaining to food or nutritive material, or to the organs of digestion. [EU] Alkaline: Having the reactions of an alkali. [EU] Alkaline Phosphatase: An enzyme that catalyzes the conversion of an orthophosphoric monoester and water to an alcohol and orthophosphate. EC 3.1.3.1. [NIH] Allergen: An antigenic substance capable of producing immediate-type hypersensitivity (allergy). [EU] Allylamine: Possesses an unusual and selective cytotoxicity for vascular smooth muscle cells in dogs and rats. Useful for experiments dealing with arterial injury, myocardial fibrosis or cardiac decompensation. [NIH] Alpha Particles: Positively charged particles composed of two protons and two neutrons, i.e., helium nuclei, emitted during disintegration of very heavy isotopes; a beam of alpha particles or an alpha ray has very strong ionizing power, but weak penetrability. [NIH] Alpha-1: A protein with the property of inactivating proteolytic enzymes such as leucocyte collagenase and elastase. [NIH] Alpha-Defensins: Defensins found in azurophilic granules of neutrophils and in the secretory granules of intestinal paneth cells. [NIH]
Dictionary 147
Alpha-helix: One of the secondary element of protein. [NIH] Alternative medicine: Practices not generally recognized by the medical community as standard or conventional medical approaches and used instead of standard treatments. Alternative medicine includes the taking of dietary supplements, megadose vitamins, and herbal preparations; the drinking of special teas; and practices such as massage therapy, magnet therapy, spiritual healing, and meditation. [NIH] Alum: A type of immune adjuvant (a substance used to help boost the immune response to a vaccine). Also called aluminum sulfate. [NIH] Aluminum: A metallic element that has the atomic number 13, atomic symbol Al, and atomic weight 26.98. [NIH] Alveolar Process: The thickest and spongiest part of the maxilla and mandible hollowed out into deep cavities for the teeth. [NIH] Alveoli: Tiny air sacs at the end of the bronchioles in the lungs. [NIH] Amebiasis: Infection with any of various amebae. It is an asymptomatic carrier state in most individuals, but diseases ranging from chronic, mild diarrhea to fulminant dysentery may occur. [NIH] Amine: An organic compound containing nitrogen; any member of a group of chemical compounds formed from ammonia by replacement of one or more of the hydrogen atoms by organic (hydrocarbon) radicals. The amines are distinguished as primary, secondary, and tertiary, according to whether one, two, or three hydrogen atoms are replaced. The amines include allylamine, amylamine, ethylamine, methylamine, phenylamine, propylamine, and many other compounds. [EU] Amino Acid Sequence: The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining protein conformation. [NIH] Amino Acids: Organic compounds that generally contain an amino (-NH2) and a carboxyl (COOH) group. Twenty alpha-amino acids are the subunits which are polymerized to form proteins. [NIH] Amino Acids: Organic compounds that generally contain an amino (-NH2) and a carboxyl (COOH) group.

Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P.
