Purpose: The purpose of this study was examined the characteristics high caries risk group for adolescents in Korea.
Methods: The oral health status and interview data were collected from 18,112 children (9,734 males, 8,378 females), aged 10, 12, and 15 years, who participated in the Korea National Oral Health Survey in 2010. The DMFT values of the subjects were sorted. The upper one third was selected as the SiCgroup (N=6,579) and the other were classified as the Middle group(N=4,466) and Caries-free group(N=7,067). This study used the demographic variables, such as gender, area of residence. The variables for the oral health behavior were the number of dental sealants of the first molar, self-perceived oral health, average frequencies of tooth brushing per day and the mean frequency of daily snack consumption. The variables for the oral health status were the mean number of DMFT, and SiC (Significant Caries) index. The associations between the demographic and social variables, oral health status, oral health related-consciousness and behavior and high risk group were evaluated by logistic regression analysis.
Results: Some of the high caries risk group had not sealant teeth on the first molar (46.8%) and lived nly in metropolitan areas (38.5%, p<0.05). The determinants of the high risk group were whether the first molar was sealed (‘0’, OR=25.4), self-perceived oral health (‘fair’, OR=1.77, ‘poor’, OR=2.93).
Conclusion: The characteristics of the high caries risk group in Korean adolescents were nothing sealant teeth on the first molar, poor self-perceived oral health, gender and age.
