Objectives : This study examined the oral health behavior and dental services utilization of adolescents in order to provide information on how to disseminate the correct oral health behavior to the youth and develop programs for the approach. Methods : The raw data of 'The Third 2007 Youth Health Behavior Online Survey' carried out by the Korea Center for Disease Control and Prevention were analyzed. All survey data collected was processed using SPSS ver 17.0 for data analysis as Frequency analysis, chi-square and Logistic regression analysis. Results : 1.The adolescents who have parents with college degree are 70% higher of dental services utilization than the adolescents counterpart(whose parents don't have degrees). And also the adolescents living in cities are 1.3 times higher use of dental services than others living in countries. 2. In case of drinking soda, students having soda 4 days per week on average are 1.2 times higher use of dental services than who don't. 3.The students brushing teeth after lunch are 0.9 times lower use of dental service than who don't. And the students who have tooth ache whenever they have a meal are 1.6 times higher use of dental service than the students who don't have tooth ache. The students who had a dental health education are 1.4 times higher utilization of dental service than who don't. The difference of using dental service between the students who have gum disease and halitosis and the students who don't is almost none. 4. The students who drink alcohol and smoke 10 days more or less a month are 0.8 ~ 0.9 times lower use of dental service than who don't. Conclusions : The rate of utilizing dental service is higher at students who live with parents having college degrees and the more have oral health behavior, the less use of dental service for treatment. We concluded that more educational program should be developed and vitalized so that students can have oral health.

Objectives : Oral care is important for workers and Korean adults to improve the quality of life and perform economic activities. This study was conducted to prepare the basic data to establish the management system for adult oral health by looking into characteristics by ages and the genders questingly. Methods : Oral health examination was conducted on workers in 2009 in the city of Gwangju and Chonnam province. This analysis was extracted using SPSS(SPSS 12.0 for windows, SPSS Inc, Chicago, USA). Results : Among the study respondents, 39.5% workers and 47.7% Korean adults answered their subjective oral health is not good, but there was no statistically significant difference between them(p< $0.001^{***}$). 39.9% workers and 2 0.6% Korean adults were smokers, and they showed a statistically significance in the ages and genders (p< $0.001^{***}$). 91.2 %workers and 49.8% Korean adults brushed their teeth before going to bed, and they showed a statistically significance in the ages and genders(p< $0.001^{***}$). In terms of the gender, male workers and Korean female adults showed high frequency of use, and both workers and Korean adults aged 18-24 showed high frequency with regard to the age. Regarding the use of oral care items, 36.0% workers and 16.9% Korean adults used them, and a statistical significance was shown in both the gender and age(p< $0.001^{***}$). In terms of the gender, female workers and Korean female adults showed high frequency of use and in terms of the age, 45-54 age bracket workers and 30-34age bracket Korean adults used the items frequently. 28.0% workers and 30.7% Korean adults answered that their mastication among oral functions is uncomfortable, and 8.8% workers and 6.5% Korean adults responded that it is hard to pronounce. They were statistically significant in the gender and age(p< $0.001^{***}$). Workers and Korean female adults expressed their mastication discomfort and men expressed that they have a difficulty in pronouncing. In terms of the age, the 54-64 age bracket workers and Korean adults express their inconvenience of mastication and pronunciation. Conclusions : According to the above findings, it needs to build the economical and efficient adult oral health care system in order to enhance both workers and Korean adults' oral health.

Objectives : The purpose of this study is to evaluate the appearance of having relationship between the exposure to lead and cadmium and the dental caries targeting adults in the Republic of Korea. Methods : The study was designed as a cross-sectional study, using the data of the Fourth Korea National Health and Nutrition Examination Survey. The subjects as 1,966 people, who were confirmed the appearance of dental caries among 1,991 people of having been offered the heavy-metal concentration in blood. Statistical analysis was conducted using SPSS 19.0, according to complex sampling design. Results : As a result of multi-variate analysis on factors of dental caries, in Model I without correction, the gender, age, educational level, appearance of lifelong smoking, daily toothbrushing frequency, appearance of using dental floss, and subjective oral health status were recognized as important factors. In Model II with correction of gender and age, the educational level, daily toothbrushing frequency, and subjective oral health status were recognized as statistically significant factors. In Model III with correction of all factors, the gender, age, educational level, appearance of using dental floss, and subjective oral health status were functioning as statistically significant factors. As a result of statistically analyzing relationship between the exposure to lead and cadmium and the dental caries targeting adults, it was analyzed that there is no significant correlation. However, in case of lead, the tendency of being grown the cross ratio of dental caries could be examined in model I, which didn't correct disturbance factor, model II, which corrected gender and age, and model III, which corrected all variables of disturbance factor. Conclusions : The exposure to lead and cadmium was indicated to have no relationship with adults' dental caries. However, a continuous research of relationship was considered to be necessary by using Korea National Health and Nutrition Examination Survey, which is surveyed in the future.

Objectives: The purpose of the study was to examine the association between diabetes mellitus and community periodontal index in Korean adults. Methods: The study populations were recruited by the Fifth Korea National Health and Nutrition Examination Survey. Study subjects were 10,411 who were examined oral examination, blood test, and aged over 19 years. Using multiple logistic regression analyses, the variables were adjusted for gender, age, household income, family history of diabetes, body mess index, smoking habit, and frequency of tooth brushing. Periodontal tissue examination of the subjects was performed and scored by Community periodontal index(CPI). Using probe, six teeth were examined for hemorrhage, plaque, and pocket depth and classified into $CPI_0$, $CPI_1$, $CPI_2$, $CPI_3$ and $CPI_4$. Healthy periodontal groups($CPI_{0-2}$) and periodontal disease groups($CPI_{3-4}$) were divided by the periodontal disease status. The definition of diabetes mellitus(DM) was decided by the diagnosis by the doctors and fasting blood sugar level. Those who were diagnosed as DM were included in DM group. The DM variables included normal blood sugar level, increased fasting blood sugar level, and DM blood sugar level. The DM variables were compared to periodontal disease blood sugar level and analyzed. Results: The periodontitis prevalence rate was 23.2%. Those who had diabetes mellitus accounted for 5.5% of the subjects. Those who had impaired fasting glucose accounted for 17.7% and 7.9% of subjects were diabetes mellitus by blood test. In the confirmed diabetes group by doctor, the periodontitis prevalence rate was significantly higher than the non-diabetic group. Diabetic group by blood test had the highest prevalence rate of periodontitis than those who had impaired fasting glucose group or normal group. After adjusting for gender, age, household income, family history of diabetes, body mass index, smoking habit, and frequency of tooth brushing, the risk of periodontitis in diagnosed diabetes mellitus was 1.57 times(95% CI; 1.27-1.94) higher than the normal group. In impaired fasting glucose group and diabetes mellitus group by blood test, the risk of periodontitis was 1.11 times(95% CI; 0.95-1.30) and 1.45 times(95% CI; 1.45-2.12) higher, respectively. Conclusions: There was a significant relationship between diabetes mellitus and periodontitis in Korean adults. These results suggest that diabetes mellitus is a risk factor for periodontitis.

Objectives: The purpose of the study is to investigate the relationship between bone mineral density and remaining teeth in Korean adults. Methods: Using National Health and Nutrition Examination Survey(KNHANES) 5th Year 1(2010), 1,985 adults over 50 years old having bone mineral density test were selected. Male adults were 883, and female adults were 1,102. The raw data consisted of general characteristics of the subjects, bone density data, and oral examination data. The questionnaire consisted of general health survey, laboratory examination study, and nutrition study. Data were analyzed using SPSS 18.0 program for multiple regression analysis, ANOVA, t-test. The variables included general characteristics of the subjects, health behavior, diet habit, and oral health behavior. General characteristics consisted of gender, age, residence area, education level, marital status, monthly income, and vocation. Health behavior consisted of smoking, alcohol drinking, body mass index(BMI), physical activity, and mental health. Diet habit consisted of frequency of meal, milk, coffee, and calcium ingestion. Oral health behavior consisted of frequency of tooth brushing, use of oral health care devices, and oral examination. Systemic diseases were measured by the questionnaire for hypertension, diabetes mellitus, and hyperlipidemia. Bone density was measured in T-score of femoral bone, neck of femur, and lumbar vertebrae. Bone density was classified into normal($T-score{\geq}-1.0$), osteopenia(-2.5 < T-score < -1.0), and osteoporosis ($T-score{\leq}-2.5$). The remaining teeth were measured by the differences between normal teeth and missing teeth. Results: Smoking and age are the most influencing factors on the number of remaining teeth and bone density(p<0.01)(p<0.05). Those who had higher bone density, younger age, and nonsmoker significantly had more remaining teeth. Those who were men, diabetic, lowly educated women, and low birth weighted persons tended to have less number of teeth(p<0.01). Conclusions: The study suggested that there were significant differences between men and women according to the oral health management behavior and systemic disease control. Proper management of the oral health and good quality of bone mineral density can reserve the remaining teeth through the whole life.
