Objectives : We supposed that identifying the influencing factors on DMFT index in the primary school children in Pocheon be indispensible for the primary school children's oral health program establishment in Pocheon. So, to prepare the basic materials for the primary school children's oral health program establishment in Pocheon, we analyzed the associated factors which could have an influence on the primary school children's DMFT index in Pocheon. Methods : We selected 3,676 primary school children in Pocheon, whose age were from 6 to 11, and surveyed those children by a questionnaire and the oral examination based on WHO's oral health survey method. Data were analyzed with a $x^2$-test and multiple regression analysis using SPSS $15.0^{(R)}$. Results : The results of oral survey in the primary school children in Pocheon revealed as follows: DMFT index, National Health Oral health survey of 2006 people nationwide in the results when compared to younger grade children and older grade in the low and the higher. Subjective oral health awareness, high of viscosity junk food snacks, fruit, gender, dental visits and humidity, oral health education classes, including the variable of attitude was 6(p<0.05). Their higher awareness of dental health, oral health education classes ever the more positive attitude to DMFT index was statistically significant(p<0.05). Solid in the habit of eating junk food snacks to the students of a liquid relative to student intake was higher DMFT index indices(p<0.05). Conclusions : We could reason that one's oral health recognition and behavior should have a relationship with his(her) DMFT index.

본 연구는 임상에서 사용되는 진단도구들이 소아에서 우식위험도와 상관관계를 가지는지 여부를 확인하고, 소아에서 우식위험도를 효과적으로 반영하는 지표가 무엇인지 알아보기 위함이다. 32명의 6세 미만의 소아를 두 군(I군 : dmft < 6, II군 : dmft > 6)으로 나누었다. Plaque-check PH을 이용해 치태의 pH를 측정하고, Saliva-check buffer를 이용해 타액의 pH와 완충능력를 측정하였다. S. mutans 검출을 위해 Saliva-check mutans와 Cytoperio analysis system을 이용하였다. 타액 완충능력은 두 군에서 유의한 차이를 보이며 dmft와 상관관계를 보였고, 타액의 pH와도 유의한 상관관계가 있는 것으로 확인되었다. 두 군 사이에 치태 pH, 타액 pH의 유의한 차이는 관찰되지 않으며 dmft와 상관관계를 가지지 않는 것으로 밝혀졌다. S. mutans의 단일클론항체를 이용하는 Saliva-check mutans와 real-time PCR에 기반한 Cytoperio analysis system은 dmft와 유의한 상관관계를 가지고 있지 않는 것으로 밝혀졌다.

This study has been conducted with continuous dental sanitary education for primary school pupils for five years from 1997 through 2001, based on data obtained from a 97' survey on primary school pupils' recognition on dental hygiene education and their permanent dental health capacity. Following results were drawn through comparative analysis of data obtained during the survey period. Approx 70.77% of the examinees have experienced decay missing feeling (DMF) in the year 2001, suggesting a good effectiveness of dental hygiene education compared with 92.1 % of DMF rate in 1997. It has been found that pupils' knowledge and recognition on dental hygiene and management, etc were improved, as well as their eating habits and consciousness were changed. Comparative analysis of annual DMF showed that DMF rate, DMFT index, and DT rate were found to decrease every year, suggesting a improved dental health capacity. Grade level analysis revealed that DMFT index and DT rate were found to decrease every year during the survey period, suggesting pupils' dental management and consciousness were improved and changed. It has been found that DMF rate more significantly increased in a higher grade in 2001 than 1997. There was no difference in DMF rate between grades of primary school in 1997. However, in the year 2001 increment of approx 10% of DMF rate were observed in a higher grade.

This study was to promote the business of school dental health program in community area and to present the improvement of oral health between public health center's group of SungDong elementary school, one that started on March 1999, and the control group that is going to operate school oral health center from 2009 in primary school. It was based on the data of more than 10 years running school based oral health section. We compared the data of SungDong group with the one of control group to get a survey of dental caries experience. The preventive effect of the caries was estimated by the difference of DMFT indices between the sample group and control group. The experience rate of caries of the sample was 12.6 percentage lower than the control group and index of the experience rate of caries for the SungDong group was two times less. It showed that the sealing rate of the SungDong group composed of pit and fissure sealant was 67.7 percentage high. The prevention rate which was calculated by DMFT index was 46.34 percentage in the SungDong group that was the highest score for the fifth grade student as a 60.5 percentage. This program contributes to the improvement of the dental caries reduction in this school oral health promotion program.

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.
