The aim of the present study was to investigate the dental caries experience in disabled people according to the handicapped types in Korea. This study subjects based on the national disabled survey 2004 were collected by designed cluster sampling and interviewed with structured questionnaire in order to examine dental caries and sociodemographic status. The subjects were attending the special schools and private or public welfare institutions for crippled disorder, encephalopathy disorder, mental retardation, visual disturbance, and hearing defect. Oral examination was conducted by 13 trained dentists. 1,307 of handicapped people were finally analysed. ANOVA and Cochran-Mantel-Hanzel analysis were adapted for statistical analysis. The results were as follows; Dental caries prevalence, DMFT(Decayed, missing, filled teeth), and DMFS(Decayed, missing, filled surfaces) of disabled people were higher in crippled disorder and mental retardation than the others. There were significant differences in dental caries prevalence, DMFT, and DMFS according to the disabled. DMFT was significantly higher than national population in every age group except in 12-14 year-old and more than 35 group. It was likely that the experience level of dental caries was significantly different according to the handicapped types in Korea and higher than the people without handicap.

Objectives : This study was to investigate the impact of dietary habits and obesity on level of oral health in the elementary school children and to characterize the relationship among dietary habits, obesity and level of oral health by DMFT index and perceived oral health. Methods : Participants were 314 total students from one elementary school who lived Yeosan. Self-administered questionnaires were given to the subjects from March 25 through May 12, 2008, to identify their the degree of dietary habits, perceived oral health. A trained investigator made an oral examination of them in natural light using a mirror and explorer to determine their DMFT index. We classified the subjects into Data were analyzed with T-test, one-way ANOVA, and Duncan's multiple range test, pearson correlation coefficient and multiple regression using the SPSS WIN 12.0 program. Results : Regarding dietary habit, the subjects achieved a mean of 10.52${\pm}$3.80 out of a maximum 20 points. The DMFT index in the subject was 0.60${\pm}$2.03. The group of obesity by gender were 19.2% and 22.5%. Moreover, those who were children and had more severe level of obesity felt that their perceived oral health and DMFT index were higher. There was a significant assocciation of oral health among elementary school children with obesity. Conclusion : These results suggest that oral health behavioral and attitude, dietary habits and obesity influenced the level of oral health. Thus further research targeting to positive attitude toward effective management of childhood obesity combined with significant dietary habits, may lead to promotion of oral health.

Objectives: The purpose of the study is to investigate the relationship between oral health status and body mass index (BMI) in adults over 65 years old. Methods: The study subjects were 4,550 adults over 65 years old from the 5th Korea National Health and Nutrition Examination Survey(KNHANES V) in 2010-2012. Mastication-related oral health status included the number of remaining teeth, and mean number of decayed, missing, and filled permanent teeth(DMFT). Body mass index(BMI, $kg/m^2$) was categorized as underweight(<18.5), normal weight (18.5-22.9), overweight(23.0-24.9), and obese(${\geq}25.0$). Multinomial logistic regression analysis was performed to examine the association of BMI categories with the number of remaining teeth and DMFT. Results: The mean number of DMFT was highest($13.0{\pm}0.7$) in the underweight group and lowest($8.8{\pm}0.3$) in the obese group. Those having less favorable masticatory ability, and fewer number of remaining teeth and no prosthesis, tended to be underweight. Those having a higher number of remaining teeth and prosthetic teeth tended to be overweight or obese. In the multinomial logistic regression analysis, compared with those having 20 or more remaining teeth, including prosthetic teeth, those having less than 20 remaining teeth and no prosthesis had 4.48 times higher odds ratio of being underweight. DMFT was positively associated with underweight, while negatively associated with overweight or obesity. Conclusions: The masticatory ability and dental caries prevention maintained the healthy body weight in adults of old age.

Objectives : The aim of the study is to investigate the oral health knowledge, attitude and dental caries experience in Korean 12-year-old adolescents. Methods : The subjects were 2,196 adolescents living in Seosan, with an average age of 12.2 years. Data were collected using a self-administered questionnaire from April 10 through June 10, 2011. A trained investigator made an oral examination of them in natural light, using a mirror and an explorer to determine their DMFT index. Results : The prevalence rate of dental caries of adolescents was 59.1%. The DMFT index of the subjects was 1.98, which was lower than the national mean of 2.2 for the same age. The DMFT index was significantly higher in the female(2.25) than the male group(1.72). The attitude of oral health was positively related to DMFT index in this study(OR=1.25; CI=1.01-1.54). It appears that knowledge and attitude concerning oral health, among young Korean 12-year-old adolescents living in Seosan, are in need of improvement. Conclusions : Based on the findings, dental caries experience is associated with attitude of oral health. This result suggests that the implementation of oral health promotion should be considered for various factors related to attitude of oral health in adolescents.

The aim of the study was to analyze the distribution of dental filling materials for carious permanent teeth of school children in a city. The study was designed as time-serial study, using the data of the dental survey for children aged 8-, 10- and 12-year children living in Gimhae city. The samples were selected by stratified clusters sampling. The number of surveyed samples in depth-analysis for types of dental filling materials were 567 in 2009 and 331 in 2013, respectively. They had dental restorations on one or more teeth. The changing pattern of used dental filling materials was analyzed between 2009 and 2013. Statistical analysis was conducted according to variables related to dental filling material type; DMFT and DMFS index, number of fissure sealed teeth and surface and surveyed year. Amalgam filling rate decreased from 27.9% in 2009 to 18.8% in 2013, while filling rate of tooth-colored materials increased from 56.1% in 2009 and 68.9% in 2013. Amalgam filling rate was a negative correlation with filling rate of tooth-colored materials or gold and number of fissure sealed teeth and a positive correlation with DMFT index. Filling rate of tooth-colored materials was a negative correlation with filling rate of amalgam or gold and DMFT index and a positive correlation with number of fissure sealed teeth. The light-curing composite resin should be included in the reimbursement range of National Health Insurance to solve an inequity of dental health care services.

Objectives: This study aims to evaluate the association between intake of energy, calcium and protein and permanent teeth caries in Korean children. Methods: Research data were obtained from the Fifth Korean National Health and Nutrition Examination Survey (KNHANES) and 1,274 Korean children within 9 to 12 years were selected as subjects for the study. The DMFT index, nutrition factors including total energy and protein intake, and degree of calcium intake were identified Chi-square test was performed to assess the difference of distribution in socioeconomic status, oral health behavior and nutrition factors according to sex. Multilevel linear regression analysis was performed to identify the relationship between DMFT index and the related variables. Results: Significant differences in energy, protein and Ca intake were confirmed according to the sex. Among 10 year-old children who intake total energy less than the recommended had few dental caries (p=0.058, ${\beta}=-0.411$). In addition, 11-year-old children having protein intake more than the recommended experienced dental caries (p=0.02, ${\beta}=0.588$). Conclusions: These results suggest that, there is significant differences between intake of energy and protein and dental caries among Korean children. However, further researches is needed to confirm between intake of energy and protein as a related factor.
