新疆阿勒泰地区青河县3-5岁汉族、哈萨克族婴幼儿龋齿流行病学调查分析

Epidemiological Investigation of Dental Caries in 3-5-year-old Chinese and Kazak Infants in Xinjiang

目的了解新疆维吾尔自治区阿勒泰地区青河县3-5岁汉族和哈萨克族儿童的婴幼儿龋患龋情况,为当地有效开展儿童乳牙防龋工作提供数据支持。方法采用分层整群的抽样方法收集了该地区幼儿园471名汉族和哈萨克族儿童的口腔检查数据样本行统计分析。结果该地区儿童婴幼儿龋龋均为(2.63±2.94),患龋率为65.82%,龋均在年龄段分布上差异有统计学意义(P<0.05)。重型婴幼儿龋龋均为(7.39±2.05),患龋率为19.75%。龋齿的充填率为5.43%。最易患龋的牙位为第二乳磨牙。结论在调查对象中乳牙患龋年龄小,龋均较高,汉族儿童的龋齿充填率明显高于哈萨克族儿童。建议相关部门尽早开始防治工作,使用汉、哈双语在学校推行口腔健康教育。

Objective To understand the caries prevalence of infantile caries in the 3-5-year-old Han and Kazak children in Altay Qinghe County, Xinjiang Uygur Autonomous Region, and provide data support for the effective development of children＇s deciduous teeth caries. Methods A stratified cluster sampling method was used to collect the statistical analysis of oral examination data of 471 Han and Kazak children in kindergartens in the region. Results The caries rate of children and infants in this area was 65.82%, the mean dmft value was（2.63±2.94）, the mean dmft value was statistically significant in age distribution. The prevalence of S-ECC all samples was19.75%, the mean dmft value was（7.39±2.05）. The filling rate of dental caries was 5.43%. The tooth position of the most susceptible caries is second primary molars. Conclusion The age of deciduous teeth decayed was small. The dental caries filling rate of the Han children was higher than that of Kazak children. It is suggested that the relevant departments should start the prevention as soon as possible.
