贵州省黔东南州苗族、侗族村寨龋病调查

Eidemiological investigation of the caries of the Miao、Dong minority people Epidemiological investigation of caries status of Miao and Dong ethic group people in Guizhou Province

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。

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 incidences and the mean DMFT of Miao are lower than Dong. However,in 35 ~ 44 and 65 ~ 74 years groups the caries incidence,the mean DMFT and root caries rate of Miao and Dong pepulation were not significantly different. CONCLUSION： Caries incidence and mean DMFT of both Miao and Dong are much higher than that of national average in 2005.
