摘要
目的：了解替牙期小学生龋病和软垢状况以及相互关系，为制定预防措施提供依据。方法：随机抽取以8～10岁为主的小学生156名，分析恒、乳牙龋损和软垢在年龄、性别上的分布，以及相互关系。结果：患龋率在年龄和性别分布上差异无统计学意义。乳牙平均患龋数明显高于恒牙平均患龋数，差异具有统计学意义。软垢均值在年龄和性别分布上差异无统计学意义。有乳牙龋的小学生软垢均值明显高于无乳牙龋者，差异有统计学意义。结论：控制软垢、定期检查和预防治疗是有效防止替牙期小学生龋病的关键。
AIM：To assess the status of primary schoolchild＇s caries and debris and the correlation between caries and debris during mixed dentition, so as to take pertinent measures to prevent caries. METHODS：One hundred and fifty -six primary schoolchilds ,who were mainly 8 - 10, were selected randomly. Then we analyzed the distribution of caries of deciduous and permanent teeth and debris in age and sex,and the relation between caries and debris. RESULTS：There was no statistical significance in the distribution of prevalence rate of caries in age and sex. There was statistical significance in average amount of caries between deciduous and permanent teeth. The average amount of caries in deciduous teeth was more than that in permanent teeth remarkably. There was no statistical significance in the distribution of debris in age and sex. There was statistical significance in debris between students with caries of deciduous teeth and students without it. The average amount of debris in students who had caries of deciduous teeth was more than that in students without it remarkably. CONCLUSION： In order to prevent primary schoolchild＇s caries during mixed dentition effectively, oral healthcare education, eliminating debris, regular check and prophylactic treatment are crucial.
