To investigate the disparity in dental caries between native and migrant children in Shanghai, China.
Between 2013 and 2015, a random cluster sample of native and migrant children aged 5, 9, 12 and 15 years was collected from each district in Shanghai. Oral examination was performed following the World Health Organization (WHO) method, and findings were reported as decayed-missing-filled teeth of primary dentition (dmft) and permanent dentition (DMFT).
A total of 10 150 children were examined, and 33.6% of them were migrants. Migrant children had a higher prevalence of deciduous caries than native children (the 5-year-old age group, 67.8% vs 63.0%, P = 0.024; the 9-year-old age group, 75.9% vs 66.1%, P < 0.001), and higher dmft values were found in migrant children. But with respect to permanent teeth, no statistical differences were found between the two groups in caries prevalence or DMFT. After controlling for potential confounders by logistic regression, migrant children showed a higher risk of deciduous caries (odds ratio 1.42, 95% confidence interval 1.25-1.61, P < 0.001) but not of permanent caries. Migrant children exhibited relatively lower deciduous Restorative Care Index (RCI). However, 9- and 15-year-old migrant children had a higher permanent RCI than their native counterparts.
Dental caries prevalence in migrant children was higher in the deciduous teeth but not in the permanent teeth compared to that in their native counterparts. School-based dental public health services may contribute to reducing the disparity in dental health status between migrant and native children.
探讨中国上海本地儿童和流动儿童的龋齿差异。
2013 年至 2015 年，采用多阶段整群抽样方法，在上海市每个区采集 5 岁、9 岁、12 岁和 15 岁的本地和流动儿童。采用世界卫生组织（WHO）方法进行口腔检查，检查结果报告为乳牙（dmft）和恒牙（DMFT）的龋齿、缺失和补牙数。
共检查了 10150 名儿童，其中 33.6%为流动人口。流动儿童乳牙患龋率高于本地儿童（5 岁年龄组，67.8%比 63.0%，P=0.024；9 岁年龄组，75.9%比 66.1%，P<0.001），dmft 值也较高。但就恒牙而言，两组间患龋率或 DMFT 均无统计学差异。经多因素 logistic 回归校正潜在混杂因素后，流动儿童患乳牙龋齿的风险更高（比值比 1.42，95%置信区间 1.25-1.61，P<0.001），但恒牙龋齿风险无差异。流动儿童乳牙修复体保留指数（RCI）较低。然而，9 岁和 15 岁的流动儿童恒牙 RCI 高于本地儿童。
与本地儿童相比，流动儿童的乳牙龋齿患病率较高，但恒牙龋齿患病率无差异。学校口腔公共卫生服务可能有助于缩小流动儿童和本地儿童在口腔健康状况方面的差距。
