台州市中小学生龋齿流行病学调查分析

目的了解台州地区中小学生龋齿患病情况,为制定口腔保健规划提供依据。方法抽取台州市2所中小学2502名学生,其中男生1501名,女生1001名；年龄7～17岁。口腔检查按照《全国学生常见病综合防治方案技术规范》进行；龋齿诊断采用世界卫生组织(WHO)龋病诊断标准。结果中小学生总患龋率为37．41%,初中生(25．51%)低于小学生(53．63%)和高中生 (31．01%),P＜0．05。患龋率最高的是9岁年龄组,达68．18%,后随年龄增加而逐渐下降,14岁以后略有回升。受检者龋均为0．86颗,患者龋均2．29颗。男女生息龋差异无统计学意义(P＜0．05)。龋齿总充填率为22．70%,小学生(7．00%)＜初中生(37．31%)＜高中生(48．00%),P＜0．05；女生 (26．23%)明显高于男生(20．30%),P＜0．01。结论学生龋齿患病率较高,龋齿充填率较低；口腔卫生知识的宣传教育和防治措施的落实需大力加强。应在学生中定期开展龋齿普查,做到早检查、早发现、早预防、早治疗。
