Am J Hypertens 2023; 36:102-108. [PMID: 36270011 DOI: 10.1093/ajh/hpac119] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 08/31/2022] [Accepted: 10/19/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Poor oral health evaluated by presence of dental calculus has been associated with hypertension (HTN) among middle- and old-aged adults. However, it is unclear for the association of HTN phenotypes with dental calculus in young adults. METHODS This study examined the association between dental calculus and HTN in 5,345 military personnel, aged 19-45 years, without antihypertensive medications therapy in Taiwan from 2018 to 2021. Dental calculus was defined as presence of supragingival calculus in any teeth, except impacted teeth, and third molar. Combined HTN (CHTN) was diagnosed as systolic blood pressure (SBP) ≥130 mm Hg and diastolic blood pressure (DBP) ≥80 mm Hg. Isolated systolic and diastolic HTN were, respectively, defined as SBP ≥130 mm Hg only (ISHTN) and DBP ≥80 mm Hg only (IDHTN). Multiple logistic regression with adjustments for sex, age, toxic substance use, anthropometrics, lipid profiles, fasting glucose, and blood leukocyte counts were used to determine the association between dental calculus and HTN phenotypes in young adults. RESULTS The prevalence of those with dental calculus, CHTN, ISHTN, and IDHTN was 20.8%, 10.8%, 10.2%, and 7.0%, respectively. The dental calculus was associated a greater possibility with CHTN [odds ratio (OR) and 95% confidence interval: 1.60 (1.31-1.95)]. However, the associations of dental calculus with ISHTN and IDHTN were null [OR: 1.05 (0.81-1.27) and 1.12 (0.86-1.46), respectively]. CONCLUSIONS Our findings suggest that among young adults, poor oral health manifested by presence of dental calculus was associated with a greater possibility of CHTN, while not for ISHTN and IDHTN.

Abstract
Background: Oral health plays an important role to maintain the general health. Therefore, controlling periodontal diseases may have a profound health effect. The importance of oral health is still a neglected and ignored social issue because most of the people are unaware of the relationship between oral health and systemic diseases. The aim of this study was to assess the knowledge and awareness of periodontal diseases among Jordan University of science and technology students. Materials and Methods: A cross-sectional study was conducted by distributing self-administered structured questionnaires to 906 university students between the ages of 18–30 years after obtaining their verbal consents. Results: A total of 906 students completed the questionnaire. Majority of students reported that they brush their teeth regularly while only 5.1% of students admitted that they never clean their teeth. Roughly one-quarter of students could define dental plaque correctly. A high “percentage” of females and medical students were more aware concerning gum inflammation signs and symptoms than males and students from faculties of engineering and science. Students of medical specialties and females were more aware of the relationship between smoking, diabetes mellitus, and heart diseases on the one hand and periodontal diseases on the other hand compared to opposite comparative groups. A low proportion of students were aware that proper scaling was not harmful to the teeth. Conclusions: In general, our study demonstrated that university students had poor knowledge regarding the etiology of periodontal diseases as well as the role of conventional treatment in maintaining good oral health by preventing the inflammatory process.

Abstract
We review the literature on the oral microbiome and the role of the microbiota in the development of dental caries and periodontitis. While most research has been focused on identifying one or more specific determinants of these diseases, the results have provided limited predictive value and have not been able to explain the variation in the distribution of these diseases observed in epidemiological or clinical studies. Drawing on existing knowledge about the nature of the oral microbiota, we suggest that a stochastic model based on the Weiner process provides simple and parsimonious explanations for the pathogenesis of both caries and periodontitis, making few assumptions, and providing explanations for phenomena that have hitherto proved difficult, or have required complex arguments, to explain. These diseases occur as the result of the dental hard tissues and periodontal tissues integrating the random "noise" caused by normal metabolic activities of commensal microorganisms in the dental biofilm. The processes that result in the progression and regression of caries and periodontitis may be considered as "natural," rather than pathological, even if, when left unchecked over long periods of time, they can result in the development of pathologies. The likelihood of progression or regression can be influenced by other determinants, but these processes will nevertheless occur in the absence of such influences. The distributional characteristics of the model approximate the findings of epidemiological studies indicating that, for both caries and periodontitis, there will be few sites affected in the early period after the eruption of the permanent dentition, but in those older there is an almost linear relationship with increasing age; furthermore, the longer a site survives without being affected, the less likely that it will be affected. We discuss the clinical and public health importance of these findings.

Abstract
Background Dental erosion (DE), one of oral hard tissue diseases, is one of the extraoesophageal symptoms defined as the Montreal Definition and Classification of gastroesophageal reflux disease (GERD). However, no study evaluated the relationship between GERD and oral soft tissues. We hypothesized that oral soft tissue disorders (OSTDs) would be related to GERD. The study aimed to investigate the association OSTDs and GERD. Methods GERD patients (105 cases), older and younger controls (25 cases each) were retrospectively examined for oral symptoms, salivary flow volume (Saxon test), swallowing function (repetitive saliva swallowing test [RSST]), teeth (decayed, missing, and filled [DMF] indices), and soft tissues (as evaluation of OSTDs, gingivitis; papillary, marginal, and attached [PMA] gingival indexes, simplified oral hygiene indices [OHI-S], and inflammatory oral mucosal regions). Clinical histories, which included body mass index [BMI], the existence of alcohol and tobacco use, and bruxism, were also investigated. A P value of <0.05 was defined as statistically significant. Results GERD patients, older and younger controls participated and aged 66.4 ± 13.0, 68.3 ± 8.2 and 28.7 ± 2.6 years old, respectively. The most common oral symptom in the GERD patients was oral dryness. Salivary flow volume and swallowing function in the GERD patients were significantly lower than in either of the controls (all P < 0.05). Inflammatory oral mucosal regions were found only in the GERD patients. The DMF indices, as a measure of dental caries, in the GERD patients were higher than in the younger controls (P < 0.001), but lower than in the older controls (P = 0.033). The PMA gingival indexes, as a measurement for gingival inflammation, and OHI-S, as a measure for oral hygiene, in the GERD patients were significantly higher than in either of the controls (all P < 0.05). Though no significant differences in BMI, the existence of alcohol and tobacco use were found, bruxism, as an exacerbation factor of periodontal disease, in the GERD patients was significantly more frequent than in either control group (P = 0.041). Conclusions OSTDs were associated with GERD, which was similar to the association between DE and GERD.

Abstract
BACKGROUND/PURPOSE Few studies have investigated the periodontal status of Taiwanese pregnant women. This study aimed to investigate the periodontal status of pregnant women and to examine its relation to oral hygiene. MATERIAL AND METHODS This study randomly recruited 477 pregnant women. Among them, 203 women were in their first trimester. Forty-six women completed the study to the end of their third trimester. We also recruited 160 nonpregnant women as the control group. Clinical periodontal parameters were recorded and included probing pocket depth [PPD (mm)], clinical attachment level [CAL (mm)], gingival index simplified [GI-s (%)], and plaque index [PI (%)]. RESULTS The GI-s of the pregnant group (PG) was higher than that of the control group [CG; (i.e., nonpregnant)], but only the third trimester was statistically significantly different (P < 0.001).The full mouth dental PI was higher in the PG than in the CG (P < 0.001), particularly in the interproximal areas. The mean PPD was greater in the PG than in the CG (P < 0.001) in all tooth areas. The mean CAL was higher in the PG than in the CG (P < 0.001), but no difference existed between the different trimesters. The CG had a higher percentage of sites with a shallow PPD, compared to the PG (P < 0.001); the PG had a higher percentage of sites with a PPD of 4-6 mm, compared to the CG (P < 0.001). Only the PI of the full mouth and lingual tooth surfaces in the third trimester were better than in the first trimester throughout the pregnancy. CONCLUSION Gingival inflammation in pregnant women is positively correlated with the increased deposition of a dental plaque biofilm.

Abstract
OBJECTIVES/HYPOTHESIS Whereas the impression that poor oral hygiene is linked to the development of sialolithiasis may be widely accepted, very few studies provide evidence to support this. This study therefore aimed to evaluate the association between chronic periodontitis (CP) and the subsequent development of salivary gland stone based on a nationwide coverage database. STUDY DESIGN A case-control study. METHODS A total of 987 subjects with sialolithiasis were included as cases. In a ratio of five controls per case, 4,935 controls matched in terms of sex and age group were selected. Conditional logistic regression analysis was performed to determine the possible association of sialolithiasis with previously diagnosed CP. RESULTS The prevalence of prior CP between cases and controls demonstrated that 1,831 (30.9%) out of the 5,922 sampled subjects had prior CP. By Chi-square test, there was a significant difference in the prevalence of prior CP between the cases and controls (36.8% vs. 29.7%, P < 0.001). By conditional logistic regression analysis, the odds ratio (OR) of prior CP for cases was 1.37 (95% confidence interval [CI], 1.19-1.56) compared to the controls after adjusting for geographic location and tobacco use. Further analyzing the relationship between sialolithiasis and prior CP according to sex, sialolithiasis was associated with prior CP regardless of sex. The adjusted OR of prior CP for the cases was 1.34 (95% CI, 1.10-1.64) and 1.41 (95% CI, 1.15-1.73) for males and females, respectively, when compared to controls. CONCLUSION This study demonstrates an association between CP and sialolithiasis. LEVEL OF EVIDENCE 3b.

Abstract
Assessment of the periodontium has relied exclusively on a variety of physical measurements (e.g., attachment level, probing depth, bone loss, mobility, recession, degree of inflammation, etc.) in relation to various case definitions of periodontal disease. Periodontal health was often an afterthought and was simply defined as the absence of the signs and symptoms of a periodontal disease. Accordingly, these strict and sometimes disparate definitions of periodontal disease have resulted in an idealistic requirement of a pristine periodontium for periodontal health, which makes us all diseased in one way or another. Furthermore, the consequence of not having a realistic definition of health has resulted in potentially questionable recommendations. The aim of this manuscript was to assess the biological, environmental, sociological, economic, educational and psychological relationships that are germane to constructing a paradigm that defines periodontal health using a modified wellness model. The paradigm includes four cardinal characteristics, i.e., 1) a functional dentition, 2) the painless function of a dentition, 3) the stability of the periodontal attachment apparatus, and 4) the psychological and social well-being of the individual. Finally, strategies and policies that advocate periodontal health were appraised. I'm not sick but I'm not well, and it's a sin to live so well. Flagpole Sitta, Harvey Danger

Abstract
Periodontal diseases are initiated by bacterial species living in polymicrobial biofilms at or below the gingival margin and progress largely as a result of the inflammation elicited by specific subgingival species. In the past few decades, efforts to understand the periodontal microbiota have led to an exponential increase in information about biofilms associated with periodontal health and disease. In fact, the oral microbiota is one of the best-characterized microbiomes that colonize the human body. Despite this increased knowledge, one has to ask if our fundamental concepts of the etiology and pathogenesis of periodontal diseases have really changed. In this article we will review how our comprehension of the structure and function of the subgingival microbiota has evolved over the years in search of lessons learned and unlearned in periodontal microbiology. More specifically, this review focuses on: (i) how the data obtained through molecular techniques have impacted our knowledge of the etiology of periodontal infections; (ii) the potential role of viruses in the etiopathogenesis of periodontal diseases; (iii) how concepts of microbial ecology have expanded our understanding of host-microbe interactions that might lead to periodontal diseases; (iv) the role of inflammation in the pathogenesis of periodontal diseases; and (v) the impact of these evolving concepts on therapeutic and preventive strategies to periodontal infections. We will conclude by reviewing how novel systems-biology approaches promise to unravel new details of the pathogenesis of periodontal diseases and hopefully lead to a better understanding of their mechanisms.

Abstract
PURPOSE The purpose of this study was to examine associations between oral hygiene, including history of periodontal disease and mouthwash use, and risk of head and neck squamous cell carcinoma (HNSCC). METHODS We measured history of oral hygiene and dental care on 513 HNSCC cases and 567 controls from a population-based study of HNSCC. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CI). RESULTS Periodontal disease was associated with a slightly elevated risk of HNSCC (OR = 1.09, 95% CI: 1.02, 1.16). Using any type of mouthwash at least once per day was associated with increased risk compared to never using mouthwash (OR = 1.11, 95% CI: 1.02, 1.20). HNSCC was associated with frequent use of non-alcoholic mouthwash compared to using any kind of mouthwash rarely or never (OR = 1.24, 95% CI: 1.05, 1.47). CONCLUSIONS Our results support an association between periodontal disease and HNSCC. Our data suggest that mouthwash use is associated with HNSCC, but we noted no difference between the effects of alcohol-containing and non-alcoholic mouthwashes.

Abstract
BACKGROUND This preliminary clinical study aimed to evaluate the effects of salivary flow volume and swallowing function on oral symptoms including dental erosion in gastroesophageal reflux disease (GERD). METHODS The subjects were 40 GERD patients and 30 (15 younger, 15 older) healthy controls. Detailed medical, dietary, and dental histories were obtained to identify individual behavioral habits potentially associated with dental erosion. Oral examination evaluated dental erosion and determined scores for the decayed, missing, filled (DMF) index, the papillary, marginal, attached (PMA) index for gingivitis, and the Simplified Oral Hygiene Index (OHI-S). Salivary flow volume and swallowing function were evaluated by the Saxon test and repetitive saliva swallowing test, respectively. RESULTS The DMF index and OHI-S scores differed significantly between all 3 groups. The PMA index was significantly different between the GERD group and the two control groups. The prevalence of dental erosion was 24.3% in the GERD group (0% in the control groups). No specific relationship was found between the incidence of dental erosion and dietary history or behavioral habits. The Saxon test results were significantly lower in the GERD group than in both the control groups. Frequency of swallowing was significantly lower and time to first swallow was significantly longer in the GERD group than in the two control groups. CONCLUSIONS Oral symptoms in GERD are likely to be associated with impaired salivary flow volume or swallowing function. Treatment for the oral dryness induced by reduced salivary flow volume and rehabilitation for swallowing function could be indicated in patients with GERD.

Abstract
BACKGROUND A newly developed bisphosphonate, TRK-530 (disodium dihydrogen[4-(methylthio)phenylthio]methanebisphosphonate), has recently been reported to show anti-inflammatory and anti-bone-resorbing activity. Since bisphosphonates have been shown to inhibit the formation of calcium-phosphate crystals in vitro, TRK-530 may inhibit the formation of dental calculus. Therefore, the present study was performed to examine whether this compound has such an effect. METHODS Three groups of Wistar rats fed a calculogenic diet (RC16) were treated with TRK-530 in drinking water at concentrations of 0 (control group), 0.75, and 1.5 mM. Another group received a daily subcutaneous injection of TRK-530 at a dose of 2.25 micromoles/rat, which was assumed to correspond to the maximum amount of this compound absorbed from the intestine when rats received 1.5 mM TRK-530 in drinking water. Rat dental calculus formation was evaluated. The crystalline nature of dental calculus was studied by x-ray diffraction analysis. Finally, the effects of TRK-530 on the precipitation of calcium-phosphate from solution were tested in vitro. RESULTS TRK-530 in drinking water inhibited dental calculus formation dose-dependently. However, subcutaneous injection of TRK-530 did not have any significant effect, suggesting that the anticalculus effect of TRK-530 in drinking water was topical, not systemic. The calculus that formed in both the control and experimental groups was primarily hydroxyapatite, a main constituent of human dental calculus. TRK-530 inhibited the precipitation of calcium-phosphate from solution in vitro. CONCLUSIONS TRK-530 inhibited the formation of dental calculus in a dose-dependent fashion via a local effect. Inhibition of the precipitation of calcium-phosphate from solution might be involved in the anticalculogenic mechanism of this drug.

Abstract
While some periodontal disease may be as old as mankind itself, caries as a public health problem appeared with the development of flour and sugar mills, and the universal access to fermentable carbohydrates. As a consequence, during the last 500 years caries and periodontal disease have been the most common diseases afflicting the human mouth. Together, these two diseases have been responsible for untold pain and suffering, and for excessive destruction and loss of people's teeth. With improving social circumstances in most industrialised nations, increased availability and affordability of modern oral health care, and the promotion of conservative treatment concepts, the 20th century saw significant progress in eliminating pain and tooth loss. Moreover, during the last 50 years advances in the oral health sciences and in technology, have not only increased our understanding of the nature of these diseases and their causes, but also introduced and tested new approaches to their prevention.

Abstract
The twigs of Diospyros lycioides, a plant commonly known as "muthala", are frequently used as chewing sticks for the cleaning of teeth by rural and urban people in Namibia. Preliminary studies showed that a methanol extract of D. lycioides inhibited growth of selected oral pathogens. Subsequent bioassay-guided fractionation led to the isolation of four novel bioactive naphthalene glycosides, diospyrosides A, B, C, and D (1-4), and two known bioactive naphthoquinones, juglone (5) and 7-methyljuglone (6). The structures of the new compounds were elucidated using spectroscopic techniques including 1D and 2D NMR. These compounds inhibited the growth of oral cariogenic bacteria (Streptococcus mutans and Streptococcus sanguis) and periodontal pathogens (Porphyromonas gingivalis and Prevotella intermedia) at minimum inhibitory concentrations ranging from 0.019 to 1.25 mg/mL. Juglone exhibited the strongest inhibitory activity among these compounds.

Abstract
BACKGROUND The aim of this study was to assess the prevalence and extent of gingival recession, gingival bleeding, and dental calculus in United States adults, using data collected in the third National Health and Nutrition Examination Survey (NHANES III). METHODS The study group consisted of 9,689 persons 30 to 90 years of age obtained by a stratified, multi-stage probability sampling method in 1988 to 1994. The weighted sample is representative of U.S. adults 30 years or older and represents approximately 105.8 million civilian, non-institutionalized Americans. Gingival recession, gingival bleeding, and dental calculus were assessed at the mesio-buccal and mid-buccal surfaces in 2 randomly selected quadrants, one maxillary and one mandibular. Data analysis accounted for the complex sampling design used. RESULTS We estimate that 23.8 million persons have one or more tooth surfaces with > or = 3 mm gingival recession; 53.2 million have gingival bleeding; 97.1 million have calculus; and 58.3 million have subgingival calculus; and the corresponding percentages are 22.5%, 50.3%, 91.8%, and 55.1% of persons, respectively. The prevalence, extent, and severity of gingival recession increased with age, as did the prevalence of subgingival calculus and the extent of teeth with calculus and gingival bleeding. Males had significantly more gingival recession, gingival bleeding, subgingival calculus, and more teeth with total calculus than females. Of the 3 race/ethnic groups studied, non-Hispanic blacks had the highest prevalence and extent of gingival recession and dental calculus, whereas Mexican Americans had the highest prevalence and extent of gingival bleeding. Mexican Americans had similar prevalence and extent of gingival recession compared with non-Hispanic whites. Gingival recession was much more prevalent and also more severe at the buccal than the mesial surfaces of teeth. Gingival bleeding also was more prevalent at the buccal than mesial surfaces, whereas calculus was most often present at the mesial than buccal surfaces. CONCLUSIONS Dental calculus, gingival bleeding, and gingival recession are common in the U.S. adult population. In addition to their unfavorable effect on esthetics and self-esteem, these conditions also are associated with destructive periodontal diseases and root caries. Appropriate measures to prevent or control these conditions are desirable, and this may also be effective in improving the oral health of the U.S. adult population.

Abstract
The objective of this research was to determine the effectiveness of a biochemical assay which measures proteolytic enzyme activity in gingival crevicular fluid (GCF) and to relate this enzyme activity to clinical parameters traditionally utilized for periodontitis detection. A clinical trial was conducted on 8 periodontitis subjects with > or =4 sites exhibiting a loss of attachment of > or =5 mm and probing depths of > or =5 mm with bleeding on probing. On each subject, a plaque index was performed, followed by GCF sampling at those sites which exhibited a loss of attachment and probing depths. GCF was analyzed for activity against benzoyl-L-arginine-p-nitroanilide in the presence (BAPNA w/gly-gly) and the absence (BAPNA w/o gly-gly) of glycyl-glycine and against MeOSuc-Ala-Ala-Pro-Val-pNA and Suc-Ala-Ala-Pro-Phe-pNA for neutrophil serine proteinases activity (elastase and cathepsin G, respectively). Subsequently, a gingival index was performed, attachment levels and probing depths were recorded using a constant force probe with bleeding on probing being noted. A split-mouth design was employed and half mouths were randomly assigned to the following treatment groups: group A, half of the mouth received scaling/root planing and polishing: group B, half of the mouth received no treatment (control). Subjects were treated, then instructed on toothbrushing and interdental cleaning. After 4 weeks, subjects returned to receive a plaque index; GCF sampling, gingival index, attachment levels, probing depths and bleeding on probing as described above. Using a paired Student t-test, the findings suggest that BAPNA w/gly-gly was significantly less in treatment sites than in non-treated control sites (p=0.05). No such correlation was found for other activities, including neutrophil serine proteinases which were shown to occur in GCF in free, proteolytically active forms. In addition, significant treatment effects were detected for probing depths (p= 0.03) which reduced by 1.3 mm and attachment levels (p=0.02) which gained 0.7 mm. The reduction of P. gingivalis from treated periodontitis sites as detected by a significant decrease in BAPNA w/ gly-gly may prove to be a valuable marker for periodontal disease activity.

Abstract
This study was conducted to evaluate the influence of hygienist services in an Israeli kibbutz (communal settlement) upon periodontal disease levels and periodontal treatment needs. The Periodontal Index (PI) and the Community Periodontal Index of Treatment Needs (CPITN) were utilised to examine 412 subjects of which 202 adult participants resided in a kibbutz employing a hygienist and 210 participants resided in one of three kibbutzim lacking a history of hygienist employment. Examinations were conducted by two calibrated examiners. Results revealed a gradual increase in the CPITN and PI scores with age and generally statistically significantly higher periodontal pathology and treatment need scores among the population not employing a dental hygienist (especially within the 35-44 age grouping). The results of this study suggest that employment of a dental hygienist may be an effective approach to lower the burden of periodontal disease within a community.

Abstract
This study evaluates the effectiveness of subgingival scaling and root planing comparing the effect of a single instrumentation to the effect of three instrumentations. A total of 35 teeth in 15 patients were selected; 15 were scaled once (Group A), 15 were scaled three times (Group B), and 5 were used as controls (Group C), representing teeth that were not instrumented. The Group A and B teeth were chosen in the same patient based on random selection. All the teeth were scored by the calculus index of the periodontal disease index. Six surface locations were probed to determine probing depth. The level of the gingival margin was marked on the teeth to locate supra- and subgingival calculus after extraction. The Group A and B teeth received the initial episode of scaling and root planing for not more than 10 minutes, then only the Group B teeth received two additional instrumentations of not more than 5 minutes each. The additional instrumentations were performed 24 hours after the initial scaling. The scaled and control teeth were extracted immediately after the third instrumentation period. The teeth were washed with water and stained with methylene blue. They were viewed under a stereomicroscope which had a tenth grid on its eyepiece. Assessments were made involving the total counts and percents of the surfaces covered with calculus on the scaled and unscaled teeth. The results demonstrated no significant difference in the effectiveness of calculus removal between single and multiple episodes of scaling and root planing. Similar results were found for the total amount of calculus removed, the calculus removed from individual surfaces, and the calculus removed from various probing depth levels.

Abstract
In this study we evaluated the traditional view that the severity of periodontal disease varies between populations in that African and Asian populations are more severely affected than other populations. Our data on periodontal destruction in two random samples of a Kenyan and a Chinese adult population were recalculated to conform with the methods of examination and data presentation utilized in each of 6 other studies of attachment loss levels in different populations. The adult Kenyan and the adult Chinese group, who had very poor oral hygiene conditions and massive gingival inflammation, had attachment loss levels which were quite similar to those in a Japanese population (31), in a Norwegian population (27) and in a New Mexico group of adults (30). Attachment losses were similar in a population of young US adults (26) aged between 35 and 60 years relative to the corresponding Kenyan and Chinese groups while young US citizens had higher and elderly US citizens had lower mean attachment levels than either Kenyans and Chinese. Higher attachment loss levels beyond the age of 27 years were reported for a population of Sri Lankan Tamil tea workers (27) and across all ages in two South Pacific island populations (29). Overall, the analysis indicates that the periodontal attachment loss profiles may differ between populations, but that these differences do not conform with the traditional generalization that African and Asian populations suffer more severe periodontal breakdown than other populations.

Abstract
In vitro studies and early clinical trials have shown promising results for Delmopinol HCl solution as an effective mouth rinse for reducing experimentally induced gingivitis in the absence of mechanical plaque control. The efficacy of Decapinol mouthwash 2 mg/mL (Delmopinol HCl) in preventing gingivitis in a double-blind, randomized clinical study with parallel group design was studied. Forty-seven healthy young adults were randomly assigned to the Delmopinol or placebo groups. After an initial period of four weeks of intensive oral hygiene including bi-weekly professional cleaning of the teeth and oral hygiene instruction, all subjects achieved a low degree of gingivitis or a plaque score close to zero. At baseline, Bleeding on Probing, Modified Gingival Index and Plaque Index were recorded and the teeth were professionally cleaned. All forms of plaque control were then suspended and subjects were supervised in a one-minute rinsing of Decapinol mouthwash 2 mg/mL or placebo twice daily. Measurements of efficacy variables were then repeated after two and three weeks treatment and adverse events were recorded. After the study period of three weeks all previous plaque control measures were resumed. At week four, all subjects were reassessed for the resolution of gingival inflammation and where residual gingival inflammation persisted, appropriate treatment was given. Only mild and short-lasting adverse events were noted for the use of Delmopinol in the study period. However, for all teeth sites measured, significant differences between Delmopinol and placebo groups were found in Bleeding on Probing (p < 0.05) and Plaque Index (p < 0.0005).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The purpose of this paper is to highlight briefly the major achievements and the remaining critical issues in the areas of epidemiology, microbiology, pathogenesis, diagnosis, and therapy. Periodontitis affects a relatively small proportion of study populations in the United States and other countries. Prevalence may be decreasing, but that remains to be seen. The identity and characteristics of susceptible individuals and groups are not known, and risk indicators for severe disease are only beginning to be identified. A very large number of different microbial species has been implicated in the etiology. It seems unlikely that all of these are essential participants. Essential participants need to be identified and better characterized. Whether putative pathogens are members of the commensal flora or exogenous species that must be transmitted is unclear. The relationship between the presence of a pathogenic flora and disease status is obscure. Pathogenic bacterial species are essential, but insufficient to cause disease. A susceptible host and local environmental factors--for example, elevated iron concentration--may be necessary for disease to occur. Many clonal types may not be virulent, and numbers greater than certain threshold levels appear to be necessary. The pathways by which bone and connective tissues of the periodontium are destroyed are sufficiently understood to permit development of therapies aimed at their modification. Examples are the use of vaccines, topical application of anti-inflammatory drugs, and use of chemically modified tetracyclines.

Abstract
Many care-dependent elderly individuals live in nursing homes and must depend on nursing home aides for oral hygiene care. It is generally agreed that the level of oral hygiene care among care-dependent nursing home residents is less than optimal. Two reasons are time constraints and the difficulty involved in brushing other individuals' teeth. The identification of effective and efficient plaque-removal devices for use by care-providers should make it easier for nursing home aides to incorporate effective oral hygiene care into their daily routines. This pilot study was undertaken to determine the relative effectiveness of four plaque removal devices with different basic designs when used by a non-professional care-provider on 10 healthy volunteers. A brush with curved bristles on the lateral aspect of the brush head and short straight bristles in the center (Collis-curve) and an electric toothbrush with tufts that rotate reciprocally (Interplak) were the most effective, a conventional brush (Oral-B) was somewhat less effective, and a disposable foam brush (Abco) was least effective and similar to the prebrushing plaque score (baseline). All the volunteers reported that the Collis-curve was the most comfortable brush, and the care-provider reported that it was the easiest to use.

Abstract
This review describes the development of periodontal index systems which during the last 50 yr have made it possible to gradually expand our understanding of the etiology and pathogenesis of periodontal diseases. Modern epidemiologic research on the prevalence and severity of periodontal diseases is based on a substantial amount of scientific data collected since the early 1940's. The work of a number of innovative researchers has eventually resulted in the clarification of one unsolved problem after the other. At the same time new ideas have been developed for the inclusion of public health aspects in the epidemiologic analyses. The assessment of periodontal treatment needs has become an issue of great importance in many countries of the world and has initiated a discussion and studies on the role of the possibilities for self-assessment of treatment needs. A completely new area of interest has developed when recent epidemiologic surveys demonstrated a substantial increase in the numbers of elderly people together with a substantial increase in the number of teeth per elderly person.

Abstract
Data from several sources demonstrate that disease-active and disease-inactive periodontal pockets exist, but currently available diagnostic procedures do not permit identification of disease-active sites at any given point in time. Using the experimental gingivitis model, we have performed studies aimed at determining whether levels of the enzyme aspartate aminotransferase (AST) in gingival crevicular fluid correlate with the presence and extent of periodontal inflammation. Gingival inflammation was assessed using the Gingival Index and the Sulcular Bleeding Index, and enzyme activity was measured using a standard procedure. Our data reveal a statistically significant association between AST values and Gingival Index scores for spontaneously occurring lesions (p less than 0.02-0.04) and experimentally induced lesions (p less than 0.0001), as well as the extent of change in these values during developing experimental gingivitis (p less than 0.0001) and resolving experimental gingivitis (p less than 0.0001). The data demonstrate that AST levels can be used to assess the presence and extent of periodontal inflammation.

Abstract
Brushing and flossing ability increased dramatically 3 weeks following 2 sessions of oral hygiene instructions. At the same time, the plaque index for these patients decreased significantly. 1 year after the oral hygiene instruction, the plaque index for these patients returned to the pre-intervention levels. However, these patients were able to maintain their 3-week post-intervention brushing and flossing scores. We conclude that increased levels of plaque 1 year later, was not due to loss of brushing and flossing skills.

Abstract
Both demographic patterns and disease distribution are changing rapidly in the United States. These developments have led to the recognition that the epidemiology of many conditions is poorly understood, and that other research has thus been hindered. Four areas of epidemiological study were chosen for detailed analysis of how new technology will affect the conduct of future research. These areas, selected because information about them will be increasingly needed in an aging society, were periodontitis, temporomandibular disorders (TMD) and other orofacial pain, salivary gland disturbances, and health services research. The potential effect of new technology was examined in the short, intermediate, and long term. While the nature of epidemiological study is unlikely to change with the advent of new technology, the scope of potential studies will become broader. Advances in diagnostic techniques from elsewhere will permit far more precise diagnosis than is possible at present. Computer technology will permit an efficient system of epidemiological surveillance to provide current data on trends in tooth loss, caries, and periodontitis--data which will complement the results of national surveys. Analytical studies to produce hypotheses on the etiology of oral conditions, especially in such poorly-understood areas as chronic pain and TMD, will help direct clinical research in those areas.

Abstract
The present study aimed to evaluate the periodontal conditions in a group of randomly selected patients scheduled for periodontal treatment in a dental school. The patients' age, sex, and responses to interview questions were used as predictors. About 64% of the lateral tooth surfaces had visible plaque after disclosure with erythrosine, and males had significantly more plaque-covered surfaces than females. All subjects had some areas showing 'bleeding on probing', and a total of 58% of the gingival units bled. About 99% of the subjects, 61% of the teeth, and 33% of the gingival sites had probing depths greater than or equal to 4 mm, whereas 70% of the subjects, 19% of the teeth, and 8% of the gingival sites had probing depths greater than or equal to 6 mm. Mean individual bone score for the 'Ramfjord teeth' was 5.60. Yearly dental visitors tended to keep their teeth to a greater extent than patients with a less regular treatment pattern. This is probably because irregular and emergency patients more often ask for extraction instead of restorative treatment. Since periodontal treatment usually is not offered, the periodontal conditions in the three regularity groups were not considerably different.

Abstract
The aim of the present investigation was to evaluate the relationship of overjet to periodontal status. Detailed examinations of occlusal and periodontal characteristics were completed on 914 12-year-old children. Plaque indices, bleeding indices, and anterior overjet were recorded for each incisor tooth. There was a significant association between mean plaque scores and the extremes of overjet measurement, suggesting that tooth cleaning is more difficult in these cases. Also, it was apparent that for right-handed children, the plaque and gingivitis scores were lower on the left side of the mouth.

Five percent of the 181 examined subjects between 25 and 60 yr were edentulous, and all dentate individuals had some degree of periodontal disease. Surfaces harboring stainable plaque were high in all age groups, varying between 65 and 85%. Surfaces without retention factors were 31% and decreased with increasing age. The percentage of sites with bleeding increased from about 40% in the lowest to about 60% in the highest age group. Teeth with probing depths greater than or equal to 4 mm increased from about 30% in the age group 25-29 yr to about 45% in the age group 30-34 yr, after which it increased gradually with increasing age. The difference in bone scores (marginal bone loss) was the most extensive between the ages of 25 and 34 yr, but with a significant increase throughout the age groups. The administrators had a somewhat better oral hygiene, fewer retention factors, less bleeding, fewer pockets and some more marginal bone support than the workers. Still, the administrators had more missing teeth than the workers.

Abstract
Gingivitis is caused by substances derived from microbial plaque accumulating at or near the gingival sulcus; all other suspected local and systemic etiologic factors either enhance plaque accumulation or retention, or enhance the susceptibility of the gingival tissue to microbial attack. Microbial species specifically associated with gingival health include Streptococcus sanguis 1, S. D-7, and Fusobacterium naviforme. Bacteria involved in the etiology of gingivitis include specific species of Streptococcus, Fusobacterium, Actinomyces, Veillonella, and Treponema and possibly Bacteroides, Capnocytophaga, and Eikenella. Microbial colonization and participation is sequential, with the complexity of the associated flora increasing with time. The pathogenesis has been separated into the initial, early, and established stages, each with characteristic features. The initial lesion is an acute inflammation which can be induced experimentally by application of extracts of plaque bacteria to normal gingiva. The early lesion is characterized by a lymphoid cell infiltrate predominated by T lymphocytes, characteristic of lesions seen at sites of cell-mediated hypersensitivity reactions. The early lesion can be induced by application of purified contact antigens to the gingival tissues of previously sensitized animals. As the clinical condition worsens, the established lesion appears, predominated by B lymphocytes and plasma cells. Established lesions may remain stable for indefinite periods of time, they may revert, or they may progress. Periodontal destruction does not result from the conversion of a predominantly T cell to a predominantly B cell lesion as has been suggested, but rather from episodes of acute inflammation. Clinical manifestations of gingivitis are episodic phenomena characterized by discontinuous bursts of acute inflammation. Most lesions are transient or persistent but not progressive. Attachment loss may precede alveolar bone loss and may occur without the manifestations of a concurrent or a precursor gingivitis. On the other hand, the evidence indicates that a portion of gingivitis lesions can and does progress to periodontitis. Gingivitis and the periodontal microflora differ in children and adults. Clinical signs of gingivitis either do not appear as plaque accumulates, or they are greatly delayed in children, and the inflammatory infiltrate consists mostly of T lymphocytes. The conversion to a B cell lesion does not appear to occur. The evidence supports the conclusion that gingivitis is a disease, and that control and prevention is a worthwhile goal and a health benefit.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
There were minimal differences in longitudinal periodontal effects when fixed and removable partial dentures were compared. Both treatment alternatives provide long-term periodontal health and should be considered for the restoration of a partially edentulous arch. Regardless of treatment, conscientious home care and professional prophylaxis are recommended.

Abstract
The investigation covered 250 professional musicians employed in 3 leading national orchestras in Stockholm, Sweden. The aims were to describe dental care habits, such as frequency of dental visits and frequency and methods of oral hygiene, and to relate these habits to oral cleanliness and gingival health in wind and non-wind instrument musicians. The results showed that 81.2% visited their dentist at least once a year and that 82.8% had had such a regular habit for the past 5 years or more. All subjects claimed to brush their teeth daily, and 66.0% used supplementary oral hygiene aids. The clinical examination showed that oral cleanliness and gingival health were of good standard. Mean plaque index was 0.9 and mean gingival index 1.2. Both measures increased with age and were closely correlated (r = 0.80). The relationships between the dental care habits studied and the clinical conditions with regard to oral cleanliness or gingival health were rather weak, although trends towards better gingival condition and oral cleanliness were observed with increasing frequency of toothbrushing. The results indicate a high degree of dental conscientiousness in professional musicians. No differences were observed between wind and non-wind instrument musicians.

Abstract
The effect of chlorhexidine on early plaque formation was studied in vivo in order to assess potential structural and quantitative changes. 3 subjects with healthy gingiva were used. Plastic films were applied to the buccal surfaces of the maxillary right first premolars and plaque was allowed to form for either 4 or 24 h. A single 1-min rinse with 0.2% chlorhexidine digluconate was used for the 4-h experiments, 1 min after film placement, whereas, for the 24-h experiments, an additional 1 min rinse was used at 12 h. In total, 62 films were obtained, half treated and half controls. These were processed for light and transmission electron microscopy, using standardized techniques for area sampling and cell counting. All plastic films were covered by a surface coating of acellular material in or on which bacteria, epithelial cells and leukocytes were observed. In the controls, an important increase in bacterial count was seen between 4 and 24 h, whereas the increase with chlorhexidine was slight. There were fewer bacteria in the chlorhexidine as compared to the water specimens, for both time periods. Many microorganisms in the chlorhexidine samples appeared to be undergoing degeneration with coagulated cytoplasm and disrupted cell walls.

Abstract
The periodontal disease trends in the nation's older adults aged 55 to 74 years are assessed using National Center for Health Statistics data spanning an approximate 12-year period. Both the 1960 to 1962 Health Examination Survey and the 1971 to 1974 Health and Nutrition Examination Survey I surveys used similar multistaged stratified probability samples. Examinations were calibrated and the collection of periodontal disease (PI), oral hygiene (OHI) and tooth loss scores were standardized. Data were collected on 1567 persons in 1960 to 1962 and 4746 persons in 1971 to 1974. The mean PI scores between the two surveys were not statistically different. However, when the periodontal diseases were divided into individuals with or without pockets, there was a significant decline in the per cent without pockets (P less than 0.001) while the per cent with pockets remained unchanged or increased. The significant reduction in OHI scores (P less than 0.02) seems to validate the decrease in gingivitis. The improvement in tooth loss was reflected by both the greater proportion of dentulous adults, and among the dentulous, a retention of more than two teeth per person by 1971 to 1974. A hypothesis is discussed regarding tooth retention and the periodontal diseases with projections for the year 2000.

Abstract
Oral examinations were performed on 102 patients receiving immunosuppressive drug therapy following renal transplantation. A further 111 control patients matched for age and sex, were also examined. The severity of dental caries of the 2 groups was compared by considering their decayed, missing and filled teeth (DMF-T), and the severity of periodontal disease was compared in terms of pocket depths, Plaque, Calculus and Sulcular Bleeding Indices, and Russell's Periodontal Index. When comparing the 2 groups, note was made of restorations involving the gingival margins, the presence of partial dentures and recent and current antibiotic therapy. No significant differences were found between the groups with regard to age, sex distribution, plaque levels, DMF and Russell's Periodontal Index. The immunosuppressed group had significantly less calculus, fewer restorations involving the gingival margins and significantly lower mean pocket depth. However, they did have more gingival recession than the controls and also a higher Sulcus Bleeding Index. All differences seen were maintained even when patients from both groups on antibiotics were eliminated from the analysis. Within the immunosuppressed group no relationship was found between the length of time the drugs were taken and the periodontal variables. The study indicates that patients on immunosuppressive therapy show no change in susceptibility to destructive periodontal disease.
