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.

Objectives : The aim of the study is to investigate the relationship between salivary flow, palate recognition threshold, DMFT index and oral health influence point (OHIP-14) of the adults over 40 years old. Methods : Salivary flow and taste recognition threshold were measured in 220 adults over 40 years old from three dental clinics in Daegu from January 3 to February 4, 2012. A total of 208 questionnaires were analyzed. Results : The adults recognized the sour taste in low concentration level when the salivary flow was faster. DMFT index was low in those who recognized sweet and sour taste that affected OHIP-14. Conclusions : Tooth decaying food must be restricted because of its high acidity in the past despite the individuals' taste recognition threshold was neglected. Before the diet control, it is necessary to measure the taste threshold of the individuals. Training for improving salivary flow is very important to prevent dental caries and to preserve good taste.

Objectives : This research analyzed the general characteristics that closely affect the children's dental health and the mothers' dental health knowledge and dental health behavior to identify the correlation of the latter with the status of children's dental health in order to provide the basic data for the development of dental health business that would target children. Methods : Research subjects were selected arbitrarily from three nursery schools located in Busan metropolitan city, targeting 186 children between the ages of four to six and their mothers. The children were subjected to dental Inspection, and the status of their dental caries was studied whereas the mothers were subjected to the surveys on the general characteristics, dental health knowledge and dental health behavior. Results : 1. Level of mothers' dental health knowledge is higher when the mothers' educational level is higher(p=0.02) and when the household's monthly income is higher(p=0.009). 2. When the level of mothers' dental health knowledge is higher, children tended to brush their toothbrushing using proper method(p=0.025). Moreover, when the level of mothers' dental health knowledge is higher, they tended to take their children to dental clinic mostly for preventive measures than for treating cavity(p=0.023). 3. When the level of mothers' dental health knowledge is higher, children's dmft index was significantly low(p=0.02). When the mothers use fluoride-containing toothpaste, children's children' dmft index was even lower(p=0.02). 4. As the children tended to brush their teeth more often, dmft index was lower(p=0.003). When the reason that the children visited dental clinic was more to prevent, than to treat cavity, dmft index was even lower(p=0.000) Conclusions : When the above mentioned results are summarized, it is possible to know that the mothers' dental health knowledge and dental health behavior significantly affect children's dental health. Accordingly, it is necessary to develop maternal and child dental health program that factors in both the mothers and children in order to prevent children's dental caries and to increase their dental health, and continued care is required to discover and treat dental caries early on.

Objectives: The purpose of the study is to investigate the relationship between oral health conditions and their subjective oral health perception in the elderly in Gimcheon. Methods: The study subjects were 214 elderly aged over 65 years old in Gimcheon. The study was carried out by direct interview method of from February 20 to 24, 2014. The oral examination was performed by the dentist base on the World Health Organization criteria including direct examination and observation. The questionnaire consisted of sex, type of family, use of medical services, and oral health behavior, The independent variable included three questions of the general characteristics of the subjects, two questions of use of medical services, and two questions of oral health behavior. The subjective oral health perception was composed of heathy and unhealthy. The objective oral health condition was evaluated by number of residual teeth, FT index, MT index, and DMFT index. Results: In the elderly, the number of residual tooth was $8.89{\pm}9.72$ and the number of decayed teeth was $0.03{\pm}0.20$. The numbers of missing teeth and filled teeth were $19.26{\pm}9.65$ and $0.28{\pm}1.01$, respectively. The DMFT index was $19.57{\pm}9.28$. In relation to the subjective oral health perception, 76.6% answered 'good' and 23.4% answered 'bad'. The subjective oral health perception showed a weak quantitative linear relationship of r=0.235 with the number of residual tooth. the subjective oral health perception showed a weak negative linear relationship(p<0.01) of r=-0.225 with the number of missing teeth and r=-0.217 with DMFT(number of decayed missing and filled teeth) index.
