贵州省黔东南州苗族、侗族村寨龋病调查

摘要

AIM:To investigate the caries status of Miao and Dong ethic group people in Guizhou Province. METHODS:According to the method used in the Third National Oral Health Survey, multi -stage stratified random sampling was used to select 800 Miao people and 800 Dong people respectively. The subjects were divided into 4 age groups (5, 12, 35~44 and 65 ~74 year-old) and their oral health was examined. RESULTS: Filling rate of root caries in 65~74 year-old Dong Groupsof both Miao and Dong people was 0%. In the 5 and 12 year old groups caries in-cidences and the mean DMFT of Miao are lower than Dong. However, in 35~44 and 65~74 years groups the caries inci-dence, the mean DMFT and root caries rate of Miao and Dong pepulation were not significantly different . CONCLU-SION:Caries incidence and mean DMFT of both Miao and Dong are much higher than that of national average in 2005.%目的:了解贵州省黔东南州苗、侗族村寨人群患龋情况. 方法:按照第三次全国口腔健康流行病学调查的标准和方法,采用多阶段分层随机抽样法对贵州省黔东南州苗、侗族(各800人)人群进行口腔健康调查,分为4个年龄组:5岁组(苗、侗族各160 人)、12 岁组(苗、侗族各432 人)、35 ~44 岁组(苗、侗族各104人)、65~74岁组(苗、侗族各104 人). 分别计算各组的患龋率、龋均及龋充填率,并进行分柝比较.结果:冠患龋率及龋均:5、12岁组苗族均低于侗族(P<0. 05),35 ~44、65 ~74 岁组苗、侗族相比无显著差异(P>0. 05). 根面龋患龋率35~44、65~74岁组苗、侗族相比均无显著性差异(P>0. 05). 5、65~74岁组苗、侗族龋充填率均为0%. 结论:贵州省黔东南州苗、侗族人群患龋情况明显高于2005年全国平均水平.
