Objectives : The purpose of this research is to use data from the third year of the 4th National Health and Nutrition Examination Survey to study relationship between oral disease and chronic disease that generally persist from 6 months to over a year, or more specifically, circulatory disease, diabetes, and osteoporosis. Methods : Of the data from the third year of the 4th National Health and Nutrition Examination Survey, 7,893 adults over 19 years old who completed medical examination, health survey, and nutrition survey were selected as the final research subjects. Relationship between chronic disease and oral disease was analyzed by cross tabulation (2-test) and logistic regression analysis using SPSSWIN ver 18.0. Results : 1. Differences in the rate of prevalence of periodontal disease and the rate of prevalence of missing teeth were statistically significant with respect to age, gender, marital status, education level, residential area, income level, and occupation. Rate of prevalence of dental caries was statistically significant with respect to age, education level, and income level. 2. After examining the relationship between existence of chronic disease as diagnosed by doctor with oral disease, rate of prevalence of periodontal disease and missing teeth, hypertension, hyperlipidemia, stroke, myocardial infarction, angina, diabetes, and osteoporosis showed statiscally significant difference. 3. Examination of rate of prevalence of chronic disease with respect to oral disease, periodontal disease and missing teeth exerted statistically significant influence on hypertension, hyperlipidemia, stroke, myocardial infarction, angina, diabetes, and osteoporosis (p<0.05), while dental caries did not have statistically significant effect. 4. Analysis of coupling effect of periodontal disease and missing teeth on chronic disease showed that they were related in all chronic diseases examined in this study (hypertension, hyperlipidemia, stroke, myocardial infarction, angina, diabetes, and osteoporosis) (p<0.05). Conclusions : Periodontal disease and missing teeth were found to increase the rate of prevalence of chronic disease.

Objectives : The purpose of this study was to examine actual conditions of smoking and alcohol drinking behaviors among high school students, so that it could recognize possible harmful effects of smoking on oral health and could give positive motivations for students to quit smoking and drinking. Methods : This research was based on self-filling survey which 1,385 high school students in metropolitan area in Korea from September 5 to October 28, 2011. Surveyed data were analyzed by descriptive statistics, ${\chi}^2$-test and logistic analysis using SPSS WIN 12.0 program and its signification level was 0.05. Results : 1. As for smoking rate and drinking rate, boy students accounted for 11.6% and 25.4%, thereby having been higher than girl students(p<.001). It was the highest in over 180 cm(16.0%, 35.0%, p<.001) for height, in 60-under 70 kg for weight(13.4%, 23.5%, p<.001), and in a case of profession for mother's job(13.8%, 28.4%, p<.005). 2. The perceived oral symptoms had relationship with the less than 10 cigarettes of smoke (OR=2.41; 95% CI:1.31-4.41), more than 11 cigarettes of smoke (OR=3.16; 95% CI:1.42-7.00) and more than 1 bottle of alcohol (OR=1.75; 95% CI:1.00-3.06). Conclusions : This result implies that adolescents' smoking and drinking have correlation with oral health status, which makes uncomfortable sense felt given chewing along with the pain in teeth and gum. Based on the above findings, a school or community needs to reinforce education for preventing smoking and drinking and to offer environment available for practicing anti-smoking and anti-drinking plan, in order to reduce adolescents' smoking and drinking.

Objectives : The purpose of this study was to examine the factors related to the dental caries and periodontal diseases of Korean elderly people in terms of demographic characteristics, oral health promotion behavior and systemic diseases in an effort to provide information on national policy setting and policy evaluation about the prevention of tooth loss resulting from severe oral diseases and the promotion of elderly people's oral health. Methods : The first-, second- and third-year raw data of the 4th National Health and Nutrition Survey were utilized, and the data of 3,882 elderly people who got a dental checkup were analyzed. The statistical package SPSS WIN 19.0 was employed to make a logistic regression analysis. Results : The senior citizens who did toothbrushing less frequently were more likely to have dental caries. As for periodontal diseases, the men were 1.34-fold more likely to have periodontal diseases than the women, and the respondents whose self-rated health state was worse were 1.40-fold more likely to have periodontal diseases than the others whose self-rated health state was better. The senior citizens who ever received treatment from unqualified people were 1.30-fold more likely to have peridontal diseases, and those who took neither vitamin compound nor minerals were 1.30-fold more likely to have periodontal diseases. Those who suffered from low High-density Lipoprotein cholesterol(HDL) were 1.35-fold more likely to have periodontal diseases than the others who didn't. Conclusions : Those whose self-rated health status is worse should especially be concerned about periodontal diseases. Specifically, it's needed to pay attention to the low-income classes, and the government should take measures to provide quality welfare services for elderly people not to receive treatment from unqualified people. Besides, research efforts should be made to determine the relationship between periodontal diseases and low HDL-cholesterolemia.

Purpose: The purpose of this study was to differences in the expression rate of Porphyromonas gingivalis according to smoking status, smoking amount and period of smoking. Methods: At the time of investigation, 30 smokers and non-smokers were recruited among patients with periodontitis with a probing pocket depth(PPD) of 4 mm or more. General information was collected using a self-questionnaire, and the average value was used by a dentist to measure the probing pocket depth of three times each for the first or second molar. Plaque collection and analysis were performed by collecting only subgingival plaque using a conventional method, and the expression rate of P. gingivalis was confirmed using polymerase chain reaction (PCR). For statistical analysis, the SPSS Ver 25.0 program was used. Results: Smoking did not have a significant effect on the expression of P. gingivalis, but it did affect the expression of more type II genotypes (p<0.05). In addition, smokers had more slight periodontal pocket, and the amount and duration of smoking did not affect the expression of P. gingivalis. Conclusions: In the future, it is necessary to reinforce the group of smokers and non-smokers with healthy oral conditions, and to investigate the quantitative difference in the expression rate and genotype of P. gingivalis over time of harmful substances in smoking.

Purpose: The aim of this study was to compare the number of live and dead bacteria attached to, or within, the stratified squamous epithelium lining the tissue side of the gingival sulcus. Materials and Methods: A total of 50 patients was examined and classified into healthy or diseased sites according to inflammatory status of the gingival tissue. The surface of stratified squamous epithelium was removed by gentle scraping of the gingival sulcus with curettes. The cells were processed in the laboratory by density-gradient centrifugation to separate the epithelial cells from the loose bacteria and debris. The LIVE/$DEAD^{(R)}$ $BacLight^{TM}$ Bacterial Viability Kit was applied and the specimens were observed by an epifluorescent microscope and the number of bacteria was counted. Results: Live and dead bacteria were stained to green and red, irrespectively. Generally, the number of total bacteria in the diseased sites was significantly higher than in the healthy sites. The mean number of detected bacteria in the diseased sites was $58.6{\pm}36.0$ (red bacteria $10.4{\pm}9.2$ / green bacteria $48.2{\pm}30.5$), while it was $1.5{\pm}1.7$ in the healthy sites (red bacteria $0.1{\pm}0.3$ / green bacteria $1.4{\pm}1.5$). The percentage of red bacteria was $17.5{\pm}11.2%$ in the diseased sites and $2.0{\pm}5.8%$ in the healthy sites. Conclusion: The total number of bacteria in the diseased sites was significantly higher than that of the healthy sites. The ratio and the number of red bacteria were also significantly higher in the diseased sites.
