Abstract:

Objective  To evaluate caries status of permanent teeth among students aged 12-15 in Hainan Province, and to provide information support for oral health prevention and health care in Hainan Province.

Methods  According to the Program of the Fourth National Epidemiological Survey of Oral Health, a total of 3 479 children aged 12-15 years in Hainan Province were selected by an equal-sized stratified multistage randomly sampling. All of them underwent a dental examination using community periodontal index(CPI) probe. SPSS 17.0 software was used for statistical analysis.

Results  The prevalence of caries of students aged 12-15 years was 60.5%, with a mean decayed-missing-filled teeth(DMFT) of 1.95. The prevalence of caries and the mean DMFT were higher in rural areas(63.9%, 2.20) than in urban areas(57.3%, 1.72), and higher in females(66.1%, 2.27) than in males(54.9%, 1.64), suggesting significant difference(P＜0.05). The prevalence of caries was the highest in mandibular first molars. The prevalence of caries in maxillary central incisors were higher than that in maxillary first molars. The filling rate of caries was 17.0%, and the rate of sealant was 1.4%. The filling rate of caries and the rate of sealant were higher in urban areas(20.5%, 2.2%) than in rural areas(14.1%, 0.5%), with significant difference(P＜0.05), but no significant difference was found between males and females(P＞0.05).

Conclusion  The prevalence of permanent teeth caries in students aged 12-15 years in Hainan Province is high, but the filling rate of caries and the rate of sealant are low. Oral health care measures should be further strengthened, especially in rural areas.
