Study 960 pupils between 6 and 12 years old of primary and secondary schools in Long Xuyen town, An Giang province. Results: rate of dental caries of deciduous teeth decreased from 5.20% to 20.55% after interventions. Rate of dental caries of permanent teeth in interventional groups decreased 3.09%-4.96% versus control group. It’s necessary to develop comprehensive dental prevention methods for school-age children.

More than 90% of Vietnamese people and children suffered from a very high prevalence of dental and periodontal diseases. In the last 10 years with the effective oral preventive project, the close cooperation with the Ministry of Education, the active response of the provincial administration, regional health and education authorities in various areas, the SDHC program has been implemented at a quick tempo, especially there appear model of SDHC complete coverage gradually district to district, province to province, 4 mios school children were covered by this program. However, there has remainly a large number of school children (7/11 mios) who are waiting for this project. But together with the SDP, it is necessary to begin the dental community-based strategy of oro-dental health care for adults, since this urgent program will meet the urgent need of oro-dental health care among adult population, whose oro-dental morbidity shows very alaming figures (50-60% of the population are affected with dental decay, and over 90% of them with gingivitis and periodontitis). Within this situation, the oro-dental diseases and the negligence of oro-dental hygiene among the population in the countryside and the moutainous region are the key factors contributing to raise up high incidence figures of this pathology: from 3 to 8 DMF teeth index/person. In some areas there is not yet practical habit of using fluoride-tooth paste, or tooth brushes for oral prevention. In almost countries in the world, their respective governments show much concern and care for community-oro-dental health. The school dental program in collaboration with the dental community program, is an effective measure to gradually rule out the dental and periodontal diseases.

Periodontal disease is the main cause of tooth loss in adults, and it is also one of the major factors affecting oral and general health. In the process of diagnosing and treating the oral diseases, many subspecialties of stomatology will involve in the maintenance of periodontal tissue health. The Chinese Stomatological Association organized a number of experts in related disciplines to thrash out the present expert consensus in order to enhance the awareness of dental clinicians to maintain the health of periodontal tissues and to standardize the procedures of diagnosis and treatment. The clinicians' abilities in prevention and treatment of oral diseases will be hopefully elevated if the clinicians, especially in such disciplines as prosthodontics, orthodontics, oral implantology, operative dentistry and endodontics, can early recognize and identify the periodontal disease and the damage degree of periodontal tissues, adopt the appropriate intervention measures and predict the prognosis scientifically.

Since the initial observations of oral bacteria within dental plaque by van Leeuwenhoek using his primitive microscopes in 1680, an event that is generally recognized as the advent of oral microbiological investigation, oral microbiology has gone through phases of "reductionism" and "holism". From the small beginnings of the Miller and Black period, in which microbiologists followed Koch's postulates, took the reductionist approach to try to study the complex oral microbial community by analyzing individual species; to the modern era when oral researchers embrace "holism" or "system thinking", adopt new concepts such as interspecies interaction, microbial community, biofilms, poly-microbial diseases, oral microbiological knowledge has burgeoned and our ability to identify the resident organisms in dental plaque and decipher the interactions between key components has rapidly increased, such knowledge has greatly changed our view of the oral microbial flora, provided invaluable insight into the etiology of dental and periodontal diseases, opened the door to new approaches and techniques for developing new therapeutic and preventive tools for combating oral polymicrobial diseases.

PURPOSE: The purpose of this study was to examine the association between the intake of semi-solid yogurt and periodontitis in Korean adults using a national database. METHODS: The data analyzed in this study are a subset of the sixth Korean National Health and Nutrition Examination Survey conducted in 2015 by the Korea Centers for Disease Control and Prevention. The sample size for this study was 4,727. We collected data on sociodemographic characteristics, oral health-related variables, oral and general health status, and intake of semi-solid yogurt. Semi-solid yogurt intake (YI) was calculated by multiplying the frequency of YI over the previous week by the average intake per serving. We assessed periodontal conditions using the Community Periodontal Index (CPI) and defined periodontitis as a CPI score ≥3. Multivariate logistic regression analyses were performed after adjusting for sociodemographic variables, and oral and general health behaviors and status. RESULTS: The mean weekly YI among those without periodontitis (1.03±0.06 cups) was significantly higher than among those with periodontitis (0.77±0.08 cups) (P<0.001). Individuals who consumed more than 2 cups of yogurt per day were 76% less likely to have periodontitis than those who consumed less than 1 cup of yogurt per week after adjusting for all covariates (odds ratio, 0.24; 95% confidence interval, 0.10–0.60). CONCLUSIONS: We found a significant association between increased intake of semi-solid yogurt and periodontal health. We therefore recommend daily consumption of semi-solid yogurt as a probiotic to improve periodontal health. Further longitudinal studies are required to elucidate plausible mechanisms through which probiotics impact periodontal disease, considering both periodontal pathogens and clinical periodontal parameters.

PURPOSE: This study aimed to investigate the effects of oral hygiene care by oral professionals on periodontal health in type 2 diabetes mellitus patients. MATERIALS AND METHODS: Diabetic participants were recruited at a university hospital and matched at a 1:1 ratio by age and gender, and randomly allocated into intervention (40 people) and control groups (35 people). Tooth brushing instruction, oral health education, and supra-gingival scaling were implemented in all patients at baseline. This program was repeatedly conducted in intervention patients every month for 6 months, and twice at baseline and the sixth month in the control. Oral health was measured by decayed, missing, and filled teeth (DMFT), plaque index, calculus index, bleeding index, patient hygiene performance (PHP) index, tooth mobility, Russel's periodontal index, and community periodontal index (CPI). Diabetes-related factors, oral and general health behaviors, and sociodemographic factors were interviewed as other confounding factors. An analysis of covariance (ANCOVA) was used with SPSS for Windows 14.0. RESULTS: At baseline, there were no significant differences between the two groups in average of periodontal health (calculus index, bleeding index, Russel's periodontal index, CPI, and tooth mobility), diabetes-related factors (fasting blood glucose, postprandial blood glucose, and HbA1c), and in distribution of sociodemographic factors and health behaviors. In intervention group, plaque index, dental calculus index, bleeding index, and PHP index were reduced fairly and steadily from the baseline. There were significant differences in plaque index, dental calculus index, bleeding index, PHP index, and Russel's periodontal index between the two groups at sixth month after adjusted for baseline status. CONCLUSION: Intensive oral hygiene care can persistently improve oral inflammation status and could slow periodontal deterioration.

OBJECTIVETo investigate the microbiological changes of subgingival microbials in patients with gingivitis and wearing fixed orthodontic appliances.

METHODS48 subjects (10 to 17 years old) with gingivitis, and wearing fixed orthodontic appliances, were divided randomly into three groups (placebo, NS and CH). Placebo group had normal saline mouthrinse; only and no oral hygiene instruction (OHI). The NS group had OHI and normal saline mouthrinse; The CH group had OHI and 0.12% chlorhexidine gluconate mouthrinse. Bacterial examinations were carried out on baseline, one week, one month and three months after scaling. The bacterial examination was carried out. The percentage of coccus, bacillus and spirochete was calculated.

RESULTSIn placebo group and NS group, the percentage of coccus increased up to the third examination then dropped down. The spirochete's percentage changed inversely. CH group maintained an increasing trend in coccus' percentage and decreasing trend in spirochete's percentage. The percentage changes of coccus and bacillus between placebo group and CH group are statistically significant (P < 0.05).

CONCLUSIONSDuring the three-month examination, the CH group had better microbiologic change than the other two groups.

INTRODUCTIONOver the past decade, there has been an emerging interest in the interrelationship between systemic conditions and oral health. Diabetes is perhaps one of the best documented conditions that have been closely linked with periodontal disease. This paper reviews the role of diabetes as a risk factor in periodontal disease. The treatment implications in the management of periodontal disease as an integral component of diabetes care is also discussed in light of the current understanding of the pathogenesis of these 2 chronic conditions.

MATERIALS AND METHODSEpidemiological, clinical and laboratory studies examining the relationship between diabetes and periodontal diseases were selected from both medical and dental journals.

RESULTSThe severity of periodontal destruction has been shown to be related to the direct and indirect effects of glycaemic control, with other factors also being implicated. Although some studies have pointed towards a bi-directional relationship between glycaemic control and periodontal health, it is still not clear if improvement in periodontal health could lead to improved metabolic control.

CONCLUSIONDiabetes and periodontal disease are closely related in many ways, though the effect of periodontal disease on diabetes control remain to be determined, with larger intervention studies. In light of the increasing evidence of the relationship between diabetes and periodontal disease, management of oral health should form an integral part of diabetes management.

OBJECTIVEThe purpose of this survey was to assess dental knowledge and behaviors of the teachers and mothers of school children.

METHODSAll data was collected from 1365 mothers of first grade students and 215 schoolteachers in Yichang, Hubei by using questionnaires and, analyzed using SPSS software.

RESULTSThe level of dental knowledge was higher among schoolteachers than among mothers; the mothers were mostly informed through television/book (62.4%/51.5%), while teachers received information from various sources, including the dentists (75.3%). Most of the children (94.0%) didn't have practical support from their parents in daily tooth cleaning. Only 18.9% of them visited the dentist at least once per year.

CONCLUSIONThis finding suggested that we should emphasize oral healthy education among mothers and schoolteachers, in order to promote school-based oral health education program.
