Abstract：Objective To investigate the prevalence of dental caries (DA) among school children aged 8 years in Pingdingshan City, and to explore the risk factors affecting the occurrence and development of DA. Methods A stratified cluster sampling method was used to select 1,762 school children aged 8 years in Pingdingshan City, and then oral examinations and questionnaire surveys were conducted according to the standard of the 3rd Chinese National Oral Health Survey. Results The prevalence rate of dental caries in the school children aged 8 years in Pingdingshan City was 84.68%, with an average decayed-missing-filled teeth (DMFT) of 4.79. The prevalence rates of dental caries and the average DMFT in suburban and rural children were higher than those in urban children, showing statistically significant differences (P<0.05).The prevalence rates of dental caries in the deciduous and permanent dentitions were 83.65% and 25.77% respectively. The factors contributing to dental caries included urban and rural types(OR=22.42), family income(OR=10.21), having a habit of snacking before going to bed(OR=8.01), not brushing teeth after eating snacks(OR=6.00), the frequency of eating dessert(OR=8.28), the method of brushing teeth(OR=8.88) and checking the brushing effect by parents(OR=9.15). Conclusions The prevalences rate of dental caries in rural and suburban children in Pingdingshan City are high; and hence, it is necessary to strengthen oral health education and dental caries prevention and control.
