摘　　要：目的了解深圳市小学生恒牙龋病分布及治疗现状,为深圳市小学生恒牙龋病防治提供参考。方法运用整群随机抽样方法,在深圳市10个区中随机抽取63所小学,合计74 308名在校学生,进行患龋情况调查。结果小学生恒牙患龋率为15.7%,龋均为0.37±0.18;不同性别、不同年龄组间的恒牙患龋率差异均具有统计学意义(P<0.05);恒牙患龋率与学生年龄之间存在关联性(P<0.05);小学生窝沟封闭率、恒牙龋充填率分别为31.17%、19.05%;控制年龄因素后恒牙龋充填率(X^2=12.897,P<0.001)和窝沟封闭率(X^2=5.659,P=0.017)的性别差异均有统计学意义(P<0.05)。结论深圳市小学生的龋齿预防需要加强。Objective To understand the distribution and treatment of dental caries among primary school studentsin Shenzhen City, and to provide a basis for prevention and treatment of dental caries of primary school students inShenzhen City.
