Abstract

Abstract: PURPOSE: To Investigate the current situation of caries of primary school students in Shanghai Pudong and Lichuan, Jiangxi province, and analyze the risk factors of dental caries, in order to provide scientific evidence for prevention and treatment of dental caries. METHODS: A stratified cluster sampling method was applied to choose 10 primary schools from Lichuan and 2 primary schools from Pudong area, respectively. A total of 1922 pupils aging from 6 to 12 were selected. Oral health examination was applied to each student and questionaire survey was conducted among their parents. The results were analyzed with SPASS 21.0 software package. RESULTS: Two hundred and sixty-one caries was found in Lichuan pupils, with the caries rate of 23.6% and DMFT being 0.37±0.766. 96 caries was found in Pudong pupils, with the caries rate of 11.8% and DMFT being 0.19±0.582. There was significant difference between two areas. Analysis of risk factors showed a significant correlation between children's pre-bedtime sweets and other bad habits, as well as low level of education of children's parents and dental caries. CONCLUSIONS: The caries of primary school students in rural areas are significantly worse than those in urban areas; bad living habits are risk factors of caries and the knowledge of caries prevention should be popularized in school students to enhance the awareness of oral health among pupils.
