目的 了解平顶山市8岁学龄儿童龋病流行状况。方法 采用分层、整群抽样的方法对平顶山市五县、三区的1 762名8岁学龄儿童(小学二年级学生)进行口腔健康检查。结果 平顶山市8岁学龄儿童患龋率84.68%,龋均4.79,农村患龋率高于城市,而乳恒牙龋齿充填率低于城市,差异有统计学意义(P＜0.05);城乡儿童患6颗及以上龋齿的概率分别为35.61%和44.20%,差异有统计学意义(P＜0.05);8岁学龄儿童乳恒牙患龋率分别为83.65%、25.77%,乳磨牙患龋与恒磨牙患龋有相关性(r=0.236,OR=11.24)。结论 平顶山市8岁学龄儿童患龋率较高,且农村高于城市,应加强儿童口腔健康教育和龋病预防控制工作,降低城乡儿童的患龋率。
Abstract
Objective To understand the epidemic status of dental caries among 8-year-old school-aged children in Pingdingshan city.
