Objectives : The purpose of the study is to investigate the risk factors of dental caries in early childhood. Methods : Subjects were 197 mothers having 5 year old children. They completed the questionnaire from June 1 to July 14, 2012. Results : At birth, the age of mother and the number of teeth experiencing dental caries showed high correlation(r=0.163, p<0.05). Early beginning(r=-0.441, p<0.05) and long period(r=0.441, p<0.05) of mix feeding were closely related to dental caries outbreak. Long period of supplementary food caused deciduous dental caries (r=0.643, p<0.001) and dental caries experience (r=0.723, p<0.001). Long period of breast feeding (r=0.261, p<0.001) also caused deciduous dental caries. Low BMI of mother was colsely related to high dental caries(r=-0.206, p<0.01). Deciduous dental caries accounted for 61.8% and the number of teeth experiencing dental caries was 68.5%. Conclusions : Appropriate breast feeding habit is the most important behavior of preventing deciduous dental caries in 5 year old children.

Dental caries is the most prevalent dental issue of childhood. So it is important to control caries form 5 years children and above all, the study of oral health status have been preceding for preventive dental caries. The purpose of this study was to assess the oral health status of 5 years children in seongnam city. The study population consisted of 1035 kindergraten children which had been selected stratified random sampling. The survey is based on WHO, 2000 oral health assessment, which has been modified. From data dt index, ft index, dft index, dt rate, ft rate, percentage of active caries, percentage of pit and fissure sealant, and so on. The findings were as follows: (1) In 5 years children, the experience of dental caries was 73.0% and the percentage with active caries was 49.4%. Dmf index was 4.13 and this observation shows a statistical singnificance. (2) Average number of 5 years children the experience of dental caries surface index was 3.11 and dfts index was 8.91. (3) The experience of dental caries fo the frist molar was 1.9% and the percentage with active caries was 1.1%. Otherwise the percentage of pit and fissure sealant of the first molar was 6.7%. It is show the low percentage for preventive dental caries. (4) Shows percentage of teeth needing treatment for one surface and above two surface was each 27.3%, 34.0%. And percentage of children required single crown and pulp treatment & single crown and tooth extraction was each 3.8%, 4.7%, 3.3%. (5) Soojung-gu and jungwon-gu were having poor oral hygiene as compared to bundang-gu. So it is necessary to establish community oral health program effectively. And for preventive dental caries and early diagnosis and early treatment consider with community characteristic.

The aim of this study was to evaluate the competency of the Easyperio test, a genetic test method based on real time PCR for the detection of bacteria that cause dental caries and periodontal disease. To verify the validity of this text, various dental health evaluations were administered to 33 boys between the ages of 12 to 14, as this age group commonly experiences dental caries. These evaluations included a dental caries experience survey, a first molar health evaluation, the Dentocult Streptococcus mutans (SM) strip mutans, the Dentocult Lactobacillus spp (LB) test, and the Easyperio test. The correlation coefficients between the level of the Dentocult SM strip mutans and the dental caries experience were DT (R=0.570, p=0.001), DMFT (R=0.376, p=0.031), and first molar health (R=-0.395, p=0.023). The correlation coefficients between the amount of SM in the Easyperio test and dental caries experience were DT (R=0.528, p=0.002), DMFT (R=0.369, p=0.035), and first molar health (R=-0.426, p=0.013). The correlation coefficients between the level of the dentocult SM strip mutans and the SM amounts of the Easyperio test were S.mi (R=0.564 p=0.001) and S.mu (R=0.621, p=0.002). The correlation coefficients between the level of the Dentocult LB test and the SM amount of Easyperio test was S.mi (R=0.495, p=0.003). In conclusion, Easyperio test may be an easy and effective method for the differentiation and diagnosis of dental caries through quantitative and qualitative analysis of oral bacteria.
