Purpose: Due to the difficulty of the hygienic care and sanitary management of abutment teeth and subpontic areas associated with fixed dental prostheses (FDPs), intrabony defects occur and accelerate due to the accumulation of plaque and calculus. This study aimed to evaluate the efficacy of regenerative periodontal surgery for intrabony defects associated with FDPs. Methods: The study inclusion criteria were met by 60 patients who underwent regenerative treatment between 2016 and 2018, involving a total of 82 intrabony defects associated with FDPs. Periodontal osseous lesions were classified as 1-, 2-, and 3-wall intrabony defects and were treated with an enamel matrix derivative in combination with bone graft material. The changes in clinical (pocket probing depth [PPD] and clinical attachment level [CAL]) and radiographic (defect depth and width) outcomes were measured at baseline and at 6, 12, and 24 months. Results: Six months after regenerative treatment, a significant reduction was observed in the PPD of 1-wall (P<0.001), 2-wall (P<0.001), and 3-wall (P<0.001) defects, as well as a significant reduction in the CAL of 2-wall (P<0.001) and 3-wall (P<0.001) intrabony defects. However, there was a significant increase in the CAL of 1-wall intrabony defects (P=0.003). Radiographically, a significant reduction in the depth of the 3-wall (P<0.001) defects and a significant reduction in the width of 2-wall (P=0.008) and 3-wall (P<0.001) defects were observed. The depth decreased in 1-wall defects; however, this change was not statistically significant (P=0.066). Conclusions: Within the limitations of the current study, regenerative treatment of 2- and 3-wall intrabony defects associated with FDPs improved clinical and radiological outcomes. Additional prospective studies are necessary to confirm our findings and to assess long-term outcomes.

Objectives : The purpose of this study was to investigate the relationship between dietary pattern and the Community Periodontal Index in elderly people who live alone in rural areas and to provide necessary data to strengthen nutrition education about the oral health of elderly people who live alone. Methods : Dental examinations and questionnaires were conducted with 380 elderly people who live alone in rural areas of Gyeonggi-do. Results : The Community Periodontal Index was higher when the elderly people who live alone had a low intake of vegetables and fruits, a high intake of sugars, a low number of breakfasts, a high frequency of overeating and a high frequency of instant ingestion. Conclusions : It is necessary to provide nutritional management services for the elderly people who live alone in rural areas and to provide preventive centered comprehensive oral care.

Objectives: The aim of this study was to examine the relationship between periodontitis, obesity, and health behavior according to sex and age in Korean adults. Methods: Data on 11,032 adults aged 19-79 years were obtained from the 7th Korea National Health and Nutrition Examination Survey (KNHNES). We used multivariate logistic regression analysis to test for associations. Results: The final model that was adjusted for demographic characteristics and health status, showed a higher risk of periodontitis with increasing body mass index (BMI), smoking, failure to use oral care products, and no dental check up. In the sub-group analysis, only smoking was significant in the 19 to 39-year-old age groups. In the 40 to 64-year-old age group, a BMI of 30 or higher, and smoking, use of oral care products, and dental check-up were significantly associated with periodontitis. In the female group, BMI, smoking, use of oral care products, and dental check-up were significantly related to periodontitis. However, in males, only smoking was significant. Conclusions: Obesity management can be helpful for periodontal health as periodontitis prevalence in adults increased as BMI increased. For periodontal health, an oral health program should include smoking cessation and the use of oral care products and dental check up as part of obesity management.

Purpose: The aim of this retrospective cross-sectional study was to evaluate whether salivary findings of active matrix-metalloproteinase 8 (aMMP-8) chairside (point of care; POC) tests were associated with periodontal risk assessment parameters in patients receiving supportive periodontal therapy (SPT). Methods: A total of 125 patients receiving regular SPT were included, and their records were examined. The following inclusion criteria were used: a diagnosis of chronic periodontitis, at least 1 non-surgical periodontal treatment (scaling and root planning) with following regular SPT (minimum once a year), at least 6 remaining teeth, and clinical and aMMP-8 findings that were obtained at the same appointment. In addition to anamnestic factors (e.g., smoking and diabetes), oral hygiene indices (modified sulcus bleeding index [mSBI] and approximal plaque index), periodontal probing depth simultaneously with bleeding on probing, and dental findings (number of decayed, missing, and filled teeth) were recorded. Salivary aMMP-8 levels were tested using a commercial POC test system (Periomarker, Hager & Werken, Duisburg, Germany). Statistical analysis was performed using the t-test, Mann-Whitney U test, Fisher's exact test, and ${\chi}^2$ test, as appropriate (P<0.05). Results: Only the mSBI was significantly associated with positive salivary aMMP-8 findings (aMMP-8 positive: $27.8%{\pm}20.9%$ vs. aMMP-8 negative: $18.0%{\pm}14.5%$; P=0.017). No significant associations were found between aMMP-8 and smoking, diabetes, periodontal parameters, or parameters related to the maintenance interval (P>0.05). Conclusions: Salivary aMMP-8 chairside findings were not associated with common parameters used for periodontal risk assessment in patients receiving SPT. The diagnostic benefit of POC salivary aMMP-8 testing in risk assessment and maintenance interval adjustment during SPT remains unclear.

Objectives: The purpose of this study was to evaluate self-reported symptoms of periodontal diseases. We performed a comprehensive analysis of periodontal health related factors. Methods: 581 volunteers representing a broad range of age from 20 to 65 were recruited from Seoul and Gyeonggi provinces. They participated in a self-administered survey of which the results were analyzed through the decision tree analysis using the data mining program. Results: 67% of the participants reported 'bad breath,' whereas 13.9% of participants reported 'toothache'. The decision analysis revealed that age was the most determining factor of adult periodontal health. Participants in 20s with a profound understanding of their periodontal health status exhibited a low vulnerability to periodontal diseases, whereas those lacking the awareness were more susceptible to the diseases. However, other participants in 30s and older showed a higher vulnerability to periodontal illness than those in 20s, whether or not they had suffered from chronic diseases. Conclusions: In order to effectively prevent periodontal diseases, an age-appropriate clinical approach will be necessary. For the younger age group it will be crucial to enhance the self-awareness of their current oral health status. On the other hand, those in 30s and older will need to pay a close attention to the prevention of chronic periodontal disease.

Objectives : This study aims to improve health and the quality of life of teenagers by identifying an association between the periodontal status and oral health behaviors of Korean teenagers using 2010 Korean National Oral Health Survey data. Methods : Subjects were teenagers aged from 12 to 15 in Korean National Oral Health Survey (KNOHS). The questionnaire consisted of periodontal status, general characteristics, periodontal related factors, and oral health related behaviors. Results : Gingival bleeding was found in 56.9% of teenagers because unhealthy periodontal status and tartars were found. Those who were 15 years old had unhealthier periodontal status than those who aged 12 years old. Those who lived in rural areas tended to have worse periodontal status than those who lived in the big cities. Access to dental floss, mouth rinsing solution and regular dental checkup tended to make the healthier periodontal status. Smokers had the worse periodontal status than the nonsmokers. Conclusions : The oral health care in the teenagers aged from 12 to 15 is very important because the permanent dentition is completed in this stage. It is necessary to lay emphasis on the oral health improvement and dental caries prevention program to the teenagers.

Background: The purpose of this study was to evaluate the association between metabolic syndrome and periodontal disease in Korean adults. Methods: This study analyzed the screening data of 12,686 adults aged ≥19 years, including demographic characteristics, lifestyle habits, and each component of metabolic syndrome, obtained from the sixth Korea National Health and Nutrition Examination Survey database. Periodontal health status was measured by the community periodontal index. Subjects with three or more risk factors were considered as having metabolic syndrome. The Rao-Scott chi-square test was performed to assess the relationships between demographic characteristics, lifestyle habits, components of metabolic syndrome, and periodontal disease. Logistic regression analysis was performed based on the complex sample to evaluate the relationship between metabolic syndrome and periodontal disease. Results: The prevalence of periodontal disease was higher among the subjects with advancing age, lower average household income and education level, those working in production, residents of eup-myeon areas, in past or current smoker, those with excessive alcohol consumption habit in a week, and reduced brushing frequency and the use of oral care products (p<0.001). Each component of metabolic syndrome was associated with higher prevalence of periodontitis in the subjects with abnormal than in those with normal levels (p<0.001). The prevalence of periodontal disease in subjects with metabolic syndrome was approximately 1.443 times higher than that in normal subjects (odds ratio,1.443; p<0.001). Conclusion: This study confirmed the association between metabolic syndrome and periodontitis in Korean adults, and further studies will be needed to determine the causal relationship between the two conditions.

Objectives: This case study was conducted to assess the changes in the oral health status of older individuals with hearing and visual impairments through home oral health care based on community care. Methods: The participants were two older adults with hearing and visual impairments. Through home visits, an oral health intervention program, including oral hygiene care and training on strengthening of oral function, was conducted once a week for 5 months. Dental hygienists performed special oral health interventions such as dental plaque control through individual tooth brushing and interdental care, training on strengthening of intraoral and extraoral muscle function, and denture care for the individuals with visual-hearing impairments. Results: The overall periodontal health status and oral muscle function improved in older adults with hearing and visual impairments. In the case of the visually impaired individuals, changes in the oral health status were oral mucosal moisture (30.1 and 37.2 points before and after intervention, respectively), salivary secretion (3.5 and 4.0 cm before and after intervention, respectively), and maximum tongue pressure (20.5 and 26.2 kPa before and after intervention, respectively). Changes in the oral health status of the hearing impaired individuals increased from 28.3 points before the intervention to 38.4 points after the intervention, and the maximum tongue pressure increased from 1.85 kPa to 23.5 kPa after the intervention. Conclusions: Oral health intervention activities contributed to improving the periodontal health and oral function of older adults with hearing and visual impairments. To improve their overall and oral health, it is necessary to prepare measures to activate customized oral health intervention programs.

Objectives: The aim of this study was to examine socioeconomic inequalities in oral health and to investigate the extent to which socioeconomic disparities in oral health are attenuated by oral health related consciousness and behaviors. Methods: We used data from the third 2006 Korea National Oral Health Survey(KNOHS) and a total of 3,457 subjects aged over 18 years were analyzed. The dependent variable was periodontal conditions which is devided into dichotomy, that is, health and ill-health, using the Community Periodontal Index(CPI) in KNOHS. Socioeconomic status(SES) were measured by educational attainment, income and residential area. Age, gender, oral health consciousness(self-assessed oral health status, concern about oral health and self-perceived dental treatment needs and behaviors(brushing, use of dental floss and dental visits) were adjusted in binary logistic regression analysis. Results and Conclusion: The results show that oral health consciousness and behaviors do not mediate the relationship between SES and periodontal health and there might be limitations to attenuate socioeconomic disparities in oral health only by changing of either oral health consciousness or(and) behaviors. Our findings suggest that more definite oral health policies and dental health education among adults with lower education will need in order to improve oral health.
