【摘要】 目的了解安徽省四县市(合肥、芜湖、阜阳、桐城)12岁及15岁儿童的龋病发病情况和特点。方法对安徽省四县市的12岁及15岁儿童的龋病发病情况进行抽样调查,采用分层、不等比、多阶段整群抽样的方法。结果两个年龄组恒牙龋均为0·58、0·95、患龋率为30·78%、39·78%,低于全国11个省市同年龄组儿童(P<0·01);恒牙龋失补构成比分别为:12岁龋90·51%、失2·48%、补7·01%;15岁龋86·78%、失4·30%、补8·92%。龋齿以窝沟龋为主,12岁年龄组中80%的龋齿发生在被调查的该年龄组人群的19·98%中;15岁年龄组中80%的龋齿发生在被调查的该年龄组人群的22·8%中。结论控制了安徽省12岁和15岁年龄组中19·98%和22·8%高危人群中的龋齿的发生,也就分别控制了这两个年龄组中80%的龋齿的发生。更多还原

The constituent ratio of DMFT was 90.51%(D), 2.48% (M), 7.01% (F) in 12-year group and 86.78%(D), 4.30% (M), 8.92% (F) in 15-year group.
