安徽省15岁年龄组恒牙龋病流行病学抽样调查分析

A Study on the Epidemiology of Permanent Tooth Caries in Children Aged15years in Anhui Province

目的了解安徽省15岁儿童的口腔健康状况及龋病发病情况。方法在全省范围内对15岁儿童的龋病发病情况进行流行病学抽样调查,采用分层、不等比、多阶段整群抽样。结果恒牙龋均0.95,患龋率39.78%,低于全国11省市同年龄组儿童(P﹤0.001);恒牙龋失补构成比分别是龋86.78%、失4.30%、补8.92%,需治疗恒牙总数2116颗,平均需治疗恒牙0.91颗。结论与全国11省市同年龄组儿童乳牙龋失补构成比相比较,安徽省15岁年龄组龋均、患龋率低于全国水平,失牙数远高于全国水平,补牙数低于全国水平(P﹤0.001)。

Objective The first study on the epidemiology of oral health status in AnHui province was held.The purpose of this survey was to investigate the prevalence of dental diseases and the needs of dental treatment,so as to develop effective programs in providing dental care in children.Methods Non-proportional stratified cluster sampling was used for this study.Results The results showed that XDMFT in this group was0.95,permanent caries prevalence rate was39.78%,lower than that of the same age children in other11provinces in Mainland(P<0.001).The proportion of DMFT was86.78%(D),4.30%(M),8.92%(F),respectively.The caries number that needed dental care were1842teeth(0.78teeth per person).Conclusion The caries prevalence rate,the XDMF and the'F'were lower than the same age children in11provinces in Mainland and the'M'was higher.
