摘　　要：目的:了解温州市5岁儿童乳牙黑色素沉着发生情况以及乳牙黑色素沉着与乳牙龋之间的相关性。方法:选取温州市6所公立幼儿园718例5岁儿童进行调查,由1名口腔医师参照WHO龋病诊断标准进行龋齿检查,同时检查记录各儿童乳牙牙面黑色素沉着情况。采用卡方检验比较有无色素沉着儿童患龋率的差别以及男女儿童色素沉着患病率的差异。采用Mann-Whitney U检验比较有无色素沉着儿童的龋失补牙数和龋失补牙面数的差异。结果:5岁儿童乳牙黑色素沉着的患病率为17.6%。有色素沉着儿童的患龋率、龋失补牙数和龋失补牙面数分别为53.2%,2.02±2.82,3.79±5.66,明显低于无色素沉着儿童(三项数据分别为73.1%,4.45±4.58,10.14±13.05,P<0.05)。结论:乳牙色素沉着和乳牙龋之间存在负相关关系。Objective：To investigate the prevalence of black stain among 5-year-old children in Wenzhou and to assess a possible association between black stain and early childhood caries（ECC）.Methods：This crosssectional study was carried out in six public kindergartens in Wenzhou,China.The study consisted of 718 5-yearold children.Caries statuses of dmft and dmfs were assessed by one calibrated dentist using WHO criteria and black stain was evaluated by the same dentist.x2 test was used to compare the difference of the prevalence of caries between the children with black stain or not.Mann-Whitney U test was used to compare the difference of dmft and dmfs between the children with black stain or not.Results：Black stain was observed in 17.6% of this population.The prevalence,dmft and dmfs of children with black stain were 53.2%,2.02 and 3.79,fewer than children without black stain（73.1%,4.45 and 10.14,P〈0.05）.Conclusion：There is a negative correlation between black stain and caries.
