Objectives: This study aims to contribute to the prevention of dental diseases and health care in the elderly by investigating the relationship among the experiences of chronic diseases, dental health status, and the behaviors in the Korean elderly people. Methods: A total of 2,856 elderly people aged 65 or older were selected as the final analysis subjects using data from the 6th National Health and Nutrition Examination Survey (2013-2014). Chronic diseases were defined as 'cardiocerebrovascular diseases', 'diabetes', 'chronic respiratory diseases', and 'cancer' diagnosed by the doctors. For the statistical analysis, SPSS 21.0 for Windows was used. Descriptive analysis and a Chi-square test were conducted to investigate the relationship among the experiences of chronic diseases, general characteristics, dental health status, and the behaviors in the Korean elderly. Finally, logistic regression analysis was performed to investigate the relationship among the experiences of chronic diseases, dental health status, and the behaviors. Results:The prevalence of Cardiocerebrovascular diseases was significantly higher in the 3-4 group of community periodontal index with the score of 1.36 (95% CI 1.03-1.00) than in the 0-2 group. The prevalence of Cardiocerebrovascular diseases was significantly higher in the group without dental examination during the past one year with the score of 1.29 (95% CI 1.00-1.66). The prevalence of diabetes was significantly higher in the uncomfortable speaking state group with the score 1.46 (95% CI 1.12-1.91). The prevalence of cancer was significantly higher in the partial denture needs group with the score 1.67 (95% CI 0.98-2.83). Conclusions: Regular dental examinations and dental health care for the elderly with chronic diseases showed that periodontal health and residual teeth could be maintained and managed. Therefore, continuous customized dental health services should be implemented for the elderly with chronic diseases.

Objectives: The purpose of the study was to analyze the association between dyslipidemia and periodontitis in Korean adults aged 30 and older. Methods: We examined 3,992 subjects participating in the 2015 Korean National Health and Nutrition Examination Survey. Periodontal status was evaluated using the community periodontal index (CPI). People with 3 or 4 CPI codes were classified as the periodontitis group. For statistical analyses, chi-square test and logistic multiple regression were used. Results: The prevalence of periodontitis was higher in men, people aged 70 and over, people whose income status was among the lower 25%, and people whose educational level was high school or lower (p<0.001). The prevalence of periodontitis was higher in people who brushed their teeth twice or less, those who did not use interdental cleaning devices, those who did not have a dental checkup in the last 12 months, and those who had not drunk or smoked (p<0.05). The prevalence of periodontitis was increased with individuals whose BMI was ≥25 kg/㎡, those whose glycated hemoglobin was ≥6.5%, and whose lipid levels were higher or lower than the normal range. In the logistic regression model, an increase in triglyceride was found to increase the prevalence of periodontitis (p<0.05). Conclusions: The study suggests that dyslipidemia, especially hypertriglyceridemia, is a predictor of periodontitis.

Purpose: To estimate the prevalence of periodontitis in Korean adults and to examine the associations between periodontitis and known risk factors. Methods: Using Korean National Oral Health Survey 2006 data, a total of 4,263 people who had taken oral examination, interviewed by questionnaire, and aged 18 or older were sampled. The prevalence of periodontitis measured by Community Periodontal Index (CPI) was calculated and the differences in prevalence according to known risk factors (age, sex, monthly income, education, residential area, tooth-brushing frequency, regular dental visit, smoking, and diabetes) were examined with chi-square test. Logistic regression analysis was performed to see the effects of each risk factor on the risk of having periodontitis. All statistical approaches were reflected national sampling design using Survey procedures in SAS 9.1. Results: The overall prevalence of periodontitis in Korean adults was 10.3%. There existed statistically significant differences in crude prevalence for periodontitis according to the all risk factors. In logistic regression, older age groups (O.R.:2.94-3.71), people living in rural area (O.R.:1.87), and current smokers (O.R.:1.77) were significantly prone to have periodontitis. People who earned monthly income of more than 2 million Korean won (O.R.:0.64) and brushed their teeth two or more times per day (O.R.:0.60-0.62) had significantly lower risk of having periodontitis. Conclusions: About 10% of Korean adults had periodontitis in 2006. People who were older, living in rural region, in lower income status, smoking, less tooth brushing were more likely to have periodontitis.

This study identified an effective control method for periodontitis by investigating the association between blood levels of vitamin D and periodontitis in Korean elderly based on raw data from the fifth Korea National Health & Nutrition Examination Survey of 2010 (KNHANES). In this study, 1,021 adults over 65 years of age were evaluated based on data from the KNHANES. Periodontal disease was assessed using community periodontal index (CPI), with CPI codes ${\geq}3$ defined as periodontitis. Blood levels of vitamin D were measured from blood samples and divided into four groups (first quartile: ${\leq}13.23ng/ml$, second quartile: 13.24~16.95 ng/ml, third quartile: 16.96~21.58 ng/ml), and fourth quartile >21.59 ng/ml). Using multiple logistic regression analyses, the variables were adjusted for general characteristics, oral health-related characteristics, health-related characteristics, and bone mineral density. The statistical analysis was performed using the SAS (ver. 9.2). The results of this study are as follows: the prevalence of periodontitis was 42.6% in Korean elderly. After adjusting for general, oral health-related, and health-related, the risk of periodontitis in the first quartile group was 1.74 times (95% confidence interval [CI], 1.02~2.98) higher than that of the fourth quartile group (p=0.041). After adjusting for general, oral health-related, and health-related characteristics as well as bone mineral density, the risk of periodontitis in the first quartile group was 1.73 times (95% CI, 1.02~2.96) higher than that of the four quartile group (p=0.042). There was a significant relationship between blood vitamin D level and periodontitis in Korean elderly. For the prevention of periodontitis, factors related to vitamin D should be considered along with other risk factors.

Background: Limited information is available regarding the associations of various nutrients and periodontitis in Korea. Furthermore, these associations have been controversial in previous studies. Therefore, the present study aimed to evaluate the associations between several nutrients and periodontitis. Methods: Pooled data from the 2007~2010 and 2012 Korea National Health and Nutrition Examination Surveys (KNHANES) were used for the present study. Periodontitis was defined using the World Health Organization (WHO) Community Periodontal Index. All participants completed the Food Frequency Questionnaire (FFQ), which was analyzed using CAN-Pro 4.0. Vitamins A, B₁, B₂, and C, iron, phosphorus, calcium, and protein were selected for analysis. Multiple logistic regression analyses were used to estimate the odds ratios (ORs) for periodontitis. Results: Lower intake of phosphorus (adjusted odds ratio [AOR] = 1.86), calcium (AOR = 1.25), and protein (AOR = 1.52) were associated with periodontitis in males, and lower intake of vitamins A (AOR = 1.32), B1 (AOR = 1.21), B2 (AOR = 1.24), and C (AOR = 1.21), iron (AOR = 1.25), phosphorus (AOR = 1.33), and protein (AOR = 1.27) showed significant relationships with periodontitis in females. In the sociodemographic, somatic, and health behavior-adjusted models, lower phosphorus (AOR = 2.68) and protein (AOR = 1.68) intake in younger males, and lower vitamin A intake (AOR = 1.37) in middle-aged females were significantly associated with periodontitis. Conclusions: The results of the present study demonstrated a significant association between periodontitis and nutrient intake. To avoid an insufficient nutrient supply for a patient with periodontal disease, the patient's diet should be closely monitored.

Purpose: The aim of this cross-sectional study was to investigate the effect of scaling and root planing (SRP) on the expression of anti-inflammatory cytokines (interleukin [IL]-4, IL-9, IL-10, and IL-13) in the gingival crevicular fluid (GCF) of electronic cigarette users and non-smokers with moderate chronic periodontitis (CP). Methods: Electronic cigarette users and non-smokers with CP were included in the study. Full-mouth plaque and gingival indices, probing depth (PD), clinical attachment loss (CAL), and marginal bone loss (MBL) were assessed. The GCF was collected, and its volume and levels of IL-4, IL-9, IL-10, and IL-13 were assessed. These parameters were evaluated at baseline and 3 months after SRP. The sample size was estimated, and comparisons between groups were performed. P<0.05 was considered to indicate statistical significance. Results: Thirty-six electronic cigarette users (47.7±5.8 years old) and 35 non-smokers (46.5±3.4 years old) with CP were included. At baseline, there were no differences in plaque index (PI), PD, CAL, MBL, and GCF IL-4, IL-9, IL-10, and IL-13 between electronic cigarette users and nonsmokers. At the 3-month follow-up, there were no significant differences in PI, gingival index (GI), PD, CAL, and MBL in electronic cigarette users compared to baseline, while there were significant reductions in PI, GI, and PD among non-smokers. At the 3-month follow-up, GCF IL-4, IL-9, IL-10, and IL-13 levels were significantly elevated in both groups (P<0.05) compared to baseline. The increases in GCF IL-4, IL-9, IL-10, and IL-13 levels were significantly higher in non-smokers (P<0.05) than in electronic cigarette users at the 3-month follow-up. Conclusions: Levels of GCF IL-4, IL-9, IL-10, and IL-13 increased after SRP in electronic cigarette users and non-smokers with CP; however, the anti-inflammatory effect of SRP was more profound in non-smokers than in electronic cigarette users.

Objectives: The purpose of the study was to examine the relationship between smoking behavior and periodontitis in Korean adults. Methods: The study subjects were 4,896 from the sixth Korean National Health and Nutrition Examination Survey. Data were analysed by chi-square test and multiple logistic regression analysis using SPSS 20.0 program. Results: The rate of periodontitis was 27.5%. The prevalence rate of periodontitis was closely related to socio-economic characteristics including gender, age, living area, household income, educational level, history of diabetes mellitus, and regular dental visit. The rate of periodontitis in non-smoker, ex-smoker, and current smoker were 56.7%, 19.5%, and 23.8%, respectively. Smoking behavior was significantly related to socio-economic characteristics. After adjusting for gender, age, household income, educational level, history of diabetes mellitus, and dental visit within 1 year, the risk of periodontitis in ex-smoker and current group were 1.31 (95% CI; 1.04-1.65) and 2.31 (95% CI; 1.87-2.85), respectively. Conclusions: Smoking behavior had a significant impact on periodontitis prevalence in Korean adults.

Objectives: The purpose of this study was to investigate the effects of general and oral health on quality of life in the elderly living alone and with family. Methods: We analyzed data from the $6^{th}$ Korea National Health and Nutrition Examination Survey. Distribution of the elderly living alone and with family based on the general characteristics and general and oral health was analyzed using complex-sample chi-square tests. Multiple logistic regression was used to analyze the factors affecting quality of life by calculating the 95% confidence intervals. Results: In the elderly living alone, the quality of life significantly correlated with restriction of activity, perceived general and oral health status, perceived stress, and speech difficulties. Further, in the elderly living with family, lower quality of life significantly correlated with restriction of activity, perceived health status, walking days per week, life time smoking history, Community Periodontal Index, and chewing and speech difficulties. Conclusions: The elderly are concerned with self-maintenance of general and oral health. Therefore, systematic policies related to health services need to be developed and operated at the national level. It is especially necessary to take social interest in the elderly living alone and a more continuous and professional approach in their health care.
