Abstract:

Objective To know the influencing factors of dental caries in first permanent molars among children aged 10-12 years old in Guangzhou, and to give references for dental caries prevention. Methods The samples were selected by stratified random sampling method. Oral health examination and questionnaires were applied to all the 18 656 children who were 5 or 6-grade in 149 primary schools. Results The prevalence of dental caries in first permanent molars was 18.19%. Girls accouted for 19.96%, which was significantly higher than that of boys (16.71%) (χ2 = 32.817, P< 0.001). Multiple regression analyses were used to investigate the influencing factors of dental caries in first permanent molars. After controlling school cluster and other factors, household register, gender, pit and fissure sealant, consumption of sweets and chocolates, consumption of sweet milk were influencing factors of permanent teeth caries. And household register, gender, pit and fissure sealant, consumption of sweets and chocolates were associated with mean DMFT. Conclusion school oral health education should focus on the consumption of sugars and cares should be put into the differences between urban and rural area. In addition, strengthening publicity of the sealant retention project,raising public awareness, and improving sealant retention quality are necessary to ensure the anti-caries effect.
