Method A total of 1 762 children aged 8 (grade two students) in five counties and three districts of Pingdingshan were interviewed by stratified cluster sampling method. Results The incidence of caries among 8-year-old school-aged children in Pingdingshan was 84.68%,with an average DMFT of 4.79.There was significant difference of caries prevalence between rural and urban areas (P＜0.05).The rate of six or more dental caries on rural and urban areas was 35.61% and 44.20% respectively,the difference was statistically significant (P＜0.05).The rate of dental caries on deciduous teeth and permanent teeth was 83.65% and 25.77% respectively.There was a direct correlation between breast teeth and constant molar (r=0.236,OR=11.24). Conclusion The caries prevalence rate of permanent teeth is relatively high.Oral health education of children and control dental caries should be strengthened to reduce the prevalence of dental caries among children.
