中文摘要：
目的了解乌鲁木齐市3～5岁维、汉儿童的龋病患病状况。方法根据世界卫生组织《口腔健康调查基本方法》和第3次全国口腔健康流行病学调查方案,随机抽样乌鲁木齐市各区9所双语幼儿园的474名3～5岁汉、维族儿童进行口腔调查,记录患龋率、龋均和充填率等指标。用SPSS17.0统计软件包进行统计学分析。结果乌鲁木齐市474名儿童乳牙患龋率为58.86%,龋均为3.6;患龋率在年龄段及民族分布上的差异有统计学意义（P〈0.05）。龋齿的充填率仅为5.43%,在年龄段、民族分布上的差异有统计学意义（P〈0.05）。样本中所有患龋儿童患龋率最高的牙位为下颌第二乳磨牙。结论乌鲁木齐市3～5岁儿童乳牙患龋早,充填率低,患龋率和龋均高。建议早期开展儿童龋病的防治工作和加强双种语言文字的口腔防治的宣教活动。
