Abstract：Objective To investigate and analyze the status of dental caries occurring in deciduous teeth and first permanent molar as well as oral behavior and habit among the school-aged children in the urban and rural areas of Weifang City so as to provide a basis and guidance for their oral health care. Methods A stratified cluster sampling method was used to select 5 urban and 5 rural primary schools in Weifang City from March to June in 2016. Dental caries in deciduous teeth and first permanent molar of the second graders from the 10 primary schools were checked; meanwhile, a questionnaire investigation on oral health behavior and habit was conducted and the relationship between dental caries and oral health behavior was analyzed. Results A total of 1,255 second graders (including 680 boys and 575 girls) received the examination of dental caries and the questionnaire survey. The prevalence rate of dental caries in deciduous teeth was 82.95%, and the filling rate of dental caries was 19.60%, with statistically significant differences between the urban and rural areas (P＜0.05), but without statistically significant differences between the genders (P＞0.05). The decayed, missing and filled tooth(dmft)of deciduous teeth was 5.15, and the differences between genders as well as between the rural and urban areas showed statistical significance (both P＜0.05). The prevalence rate of dental caries of the first permanent molar was 36.02%, and the dmft was 0.78, and the differences between the rural and urban areas as well as between genders showed statistical significance (both P＜0.05). The pit-and-fissure sealing rate was 10.04%, and the difference between the rural and urban areas showed statistical significance (P<0.05). The questionnaire survey showed that the prevalence rate of dental caries was lower in the students with the habits of brushing teeth every day, brushing teeth before going to bed, brushing teeth straight after eating sweet food and drinking low-sugar beverage (P＜0.05). Conclusions The status of dental caries of the urban and rural second graders in Weifang City in 2016 is severe, and the filling rate is low. The students’ oral health behavior and habit are poor, which are closely correlated with the status of dental caries; and hence, it is necessary to strengthen oral health prevention and treatment in the local area.
