目的了解太原市杏花岭区学龄前儿童口腔健康状况,为制定防控措施提供依据。方法选择太原市杏花岭区403名3~6岁学龄前儿童,向其家长发放调查问卷调查儿童一般情况、口腔卫生行为习惯和就医行为,并进行龋齿检查。结果回收有效问卷271份,有效率67.25%,学龄前儿童患龋196例,患龋率72.32%,龋均3.51,患龋率随年龄增加呈升高趋势(P<0.05),且左右相对应的同一牙位的同一牙面可能对称患病。刷牙次数和使用牙刷类型不同的儿童患龋率差异有统计学意义(P<0.05),两两比较发现不刷牙与刷牙儿童的患龋率差异有统计学意义(P<0.007),但与不同刷牙次数的患龋率差异均无统计学意义(P>0.007)。结论太原市杏花岭区学龄前儿童患龋率较高,龋齿多发,呈对称性患病,学龄前儿童的口腔保健行为有待改善。
