新疆地区5岁维吾尔族儿童龋病调查分析

Prevalence of deciduous tooth caries in Uygur children aged 5 years in Xinjiang Uygur Autonomous Region

目的了解新疆地区维吾尔族5岁维吾尔族儿童乳牙患龋情况，为有效开展儿童口腔保健工作提供依据。方法参照世界卫生组织《口腔健康调查基本方法》，以及第三次全国口腔健康流行病学调查方案，在新疆地区3个城市、3个农村随机抽样选取调查点，共调查782名5岁维吾尔族维吾尔族儿童的患龋情况，并将调查结果与第三次全国口腔健康流行病学西部抽样调查结果进行比较。结果新疆维吾尔族5岁维吾尔族儿童乳牙患龋率为65．35％，患儿中龋齿数最多为16个，龋均为3．30；乳牙患龋率和龋均在男性和女性、城市和农村维吾尔族儿童之间的差异均不具有统计学意义，而乳牙龋齿充填率则存在性别和地区间的差异。结论新疆地区维吾尔族5岁维吾尔族儿童乳牙龋齿患病率仍然较高，而龋齿充填率相对较低，今后维吾尔族儿童龋病防治工作应加强乳牙保健的口腔卫生宣传教育，提高保健人员和家长的口腔保健意识，培养幼儿良好的口腔卫生习惯，发现龋病及时治疗。
