目的了解山东省12岁年龄组人群恒牙龋病情况,为山东省牙病防治工作提供依据。方法2005年9-12月山东省牙病防治指导组根据经济发展情况选择山东省有代表性的市和县,即济南市市中区、威海市环翠区、济宁市兖州市、章丘市、平原县、费县,每个市(县)抽取3个乡镇。采用多阶段分层等容量随机抽样方法选择12岁年龄组的青少年,共781人。采用第三次全国口腔健康流行病学调查龋病调查标准,调查恒牙龋病情况。结果山东省12岁年龄组人群恒牙患龋率为33.4%,龋均0.55,龋齿充填率15.9%,窝沟封闭率3.8%,含氟牙膏使用率29.9%。女性患龋率和龋均(38.0%,0.63)均明显高于男性(28.8%,0.46)(P<0.05),城乡间无明显差别;城市12岁年龄组人群充填率、窝沟封闭率及含氟牙膏使用率高于农村,差异有统计学意义(P<0.05);山东省患龋率、龋齿充填率和窝沟封闭率均明显高于全国水平(P<0.05),龋均没有明显差别。结论山东省12岁年龄组人群牙病防治工作10年来取得了一定成效,但牙病的防治措施仍有待进一步加强,尤其是农村地区。
Objective To understand the prevalence of dental caries among 12-year-olds in Shandong Province and to provide basis for the prevention and treatment of dental diseases in Shandong Province.

Results The prevalence of dental caries in the 12-year-old group was 33.4%, caries was 0.55, caries filling rate was 15.9%, pit and fissure confinement rate was 3.8%, and fluoride toothpaste utilization rate was 29.9%. There was no significant difference between urban and rural areas in the incidence of dental caries and caries (38.0%, 0.63) among women (28.8%, 0.46) (P0.05). The caries prevalence rate, caries filling rate and pit and fissure sealant rate in Shandong Province were significantly higher than those in the whole country (P0.05), and there was no obvious caries difference. Conclusion The prevention and treatment of dental diseases in the 12-year-old population in Shandong Province have achieved some success in 10 years.
