重庆市3804例学龄前儿童龋病调查分析

Survey on dental caries among 3804 preschool children in Chongqing

目的:了解重庆市南岸区学龄前儿童的龋齿患病状况,为儿童保健工作提供基础数据。方法:整群抽样调查27个幼儿园共3804例儿童,用视诊结合探针检查的方法对龋病进行诊断,计算不同性别不同年龄儿童的龋病检出率和龋均指标,并比较其差别。结果:受检儿童的龋病检出率27.1%,在2～6岁组,随年龄增大,龋病检出率随之增加;受检儿童的龋均3.7,在3岁与4岁、3岁与5岁、3岁与6岁儿童间龋均的差异有统计学意义(P<0.05)。性别间的龋病检出率与龋均差异均无统计学意义。结论:受检儿童的龋病患病不容乐观,4岁之前是学龄前儿童防龋的关键时期,应特别重视4岁及以下儿童的口腔保健。

Objective：To investigate the prevalence of dental caries among preschool children in Nanan district of Chongqing so as to provide some basic data for children health care.Methods：3 804 preschool children in the 27 kindergarten of Nanan district were investigated by cluster random sampling.Visual examination combined with the probe inspection was used to diagnose caries and detection rate of caries and DMFT（decayed,missing and filled teeth）in different ages of children in different sex groups were calculated and their differences were also compared.Results：Detection rate of caries among subjects were 27.1%.In the 2～6 age group,the detection rate of caries grows with age increasing and DMFT were 3.7.In 3～4 age group,3～5 age group,3～6 age group,the differences among DMFT were statistically significant.The difference of the detection rate of caries and DMFT between sex were not statistically significant.Conclusion：It can not be optimistic about the caries prevalence rate among the subjects.The period before the age of four are critical time for preschool children to prevent caries happening.More attention should be payed to oral cavity health of children under age of 4.
