Objective To know the caries status of the first permanent molars of children aged 8-10 years in an area in Huaian City so as to provide the evidence for prevention and control of children＇s caries disease. Methods The children aged 8-10 years from four schools were selected by the stratified cluster sampling method. The caries status of the first permanent molars was investigated, and the differences between/among the areas, gender and age were compared. Results The prevalence rate of the first permanent molars was 5.85%. The prevalence rate of the suburban children （7.68%） was significantly higher than that of the downtown children （3.83%）; the prevalence rate of the female children （6.71%） was higher than that of the male children （5.15%）; the prevalence rate of the lower teeth （4.59%） was higher than the upper teeth （2.82%）. There were significant differences between the areas, gender, and upper and lower teeth （P〈 0.05）. Conclusion The prevalence rate of the first permanent molars of children aged 8-10 years in an area in Huainan City is lower than the level in Gusu area in Suzhou City （17.27%）. However, it is still necessary to strengthen the oral health education and take measures of pit and fissure sealant early to prevent and control children＇s caries disease.
