The aim of this study was to evaluate the association between obesity and periodontal diseases in Korea adults. The date from the 2015 Korean National Health and Nutrition Survey were used, and 4,827 subjects over 19 years were included in the analysis. Periodontal disease was assessed using the Community Periodontal Index. Obesity was measured according to body mass index. Odd ratios (ORs) were estimated using binary logistic regression analysis model. The stratification variables were smoking and diabetes, and also adjusted for sex, age, and education level. The adjusting variables included sex, age, and education level. The ORs of obesity for periodontal disease were 0.78 (95% CI = 0.51-1.22) for the category of <18.5 of BMI and 1.29 (95% CI = 1.11-1.49) for the ${\geq}25$ BMI category (both compared to the 18.5 to 24.9 category). In a subgroup analysis, the OR of BMI among those who were both non-smoking and no diabetes was 1.20 (95% CI = 1.02-1.48) for those with BMI levels ${\geq}25$. This study implies that obesity intolerance may be an independent risk factor for periodontal diseases. Obesity should also be considered when managing periodontal disease to improve oral health.

This study aims to investigate the factors affecting tooth loss and the association between smoking and tooth loss, by using the forth Korea National Health and National Examination Survey(2007-2009) of 1,565 elderly people over 65 years old. In terms of the characteristics, as age increases, tooth loss increases. In particular, according to the results of the analysis that identify the correlation between smoking to gender, socio-economic status and dental visiting patterns after correcting socio-economic factors and behavior, it is clear that male's tooth loss is higher than female's in current smoking and tooth loss is caused highly in the lower socio-economic status. In the dental visiting patterns, tooth loss is high when visiting more than twice a year. Therefore, it seems to need a preventive non-smoking policy at the level of dental services through further studies.

Objectives: The purpose of this study is to garner useful information through a comparative analysis of health behaviors and health states between the young-old and old-old elderly in a rural Korean area. Methods: We define the young-old elderly as those 65 to 74 years of age, and the old-old as those over 70. The survey was administered in October and November of 2009 at senior citizen centers in Sangju City, Kyongsangbuk-do, South Korea. The number of subjects surveyed approximated the demographics of the aged population of the administrative district of centers of 24 eup, myeon, and dong. Results: Compared with the young-old elderly, the old-old were vulnerable to population sociological characteristics. While there were many cases of contraction of diseases, only a small percentage of old-old elderly were engaged in regular exercise. In addition, the old-old elderly lagged behind the young-old in terms of physical activity, mental and oral health, hearing, and vision. Conclusions: The vulnerability of the old-old elderly in terms of physical and mental health needs to be acknowledged as various characteristics of the elderly that appears according an age group. A variety of disease prevention and health promotion programs that focus on the health behavior and status of the young-old and old-old elderly need to be developed and put into practice.

Objectives : The purpose of this study was to examine the amount of daily fluoride intake among children using fluoride-containing dentifrice in an effort to pave the way for the selection of criteria for the development of safe dentifrice for different age groups to make a contribution to children's oral health. Methods : This study was implemented over approximately six months from May to October 2008 by recruiting subjects, asking their consent, conducting a survey, collecting samples and analyzing the collected data. The subjects in this study were preschool residents in Seoul and Gyeonggi province, who were at the western age of 2 to 5. The amount of fluoride withdrawn from their one-time toothbrushing was measured in two different ways. One was by using HMDS-facilitated modified diffusion method and fluoride ion electrode, and the other was by applying ion chromatography without the diffusion procedure. Results : The fluoride intake accounted for $46.5{\pm}19.1$ percent of the amount of fluoride used, and that percentage was statistically significantly different according to age(p<0.01). The one-time fluoride intake from dentifrice per weight(kg) was a mean of $0.009{\pm}0.006mg$. As a result of multiplying this amount by daily toothbrushing frequency, the daily fluoride intake from dentifrice per weight(kg) appeared to be $0.023{\pm}0.016mg$ on average. There was a large difference among the children in that regard, since that ranged from a low of 0.003mg to a high of 0.070mg. And age made a statistically significant difference to that(p<0.01). Conclusions : The above-mentioned findings of the study showed that the children's daily fluoride intake from dentifrice per weight was lower than the recommended daily fluoride intake from diets per weight for young children aged 1 to 12(0.05-0.07mg). However, there was a great disparity among the children in that aspect, and they are likely to take more fluoride from other things as well. Therefore it is required to prepare separate criteria for preschool and school-aged children.
