摘　　要：本文对沈阳市１２６小学２７２名九岁儿童的牙齿龋病情况进行调查。应用菌斑ｐＨ值转化试验，分析菌斑与乳牙和恒牙龋病的关系。结果显示，依据ｐＨ值大小分组的儿童，其各组间ＤＭＦＴ和ｄｍｆｔ均存在显著性差别（Ｐ＜０．０１）。ｐＨ值分别与ＤＭＦＴ和ｄｍｆｔ呈负相关。作为龋病活跃性试验的一种，菌斑ｐＨ值转化实验能够反映混合牙列期牙齿龋蚀状况，为混合牙列期龋病预防提供依据。This article reported the results of an invesigation on dental caries of nineyearold children in the No126 primary school in Shenyan The pH value of dental plaque transferring test was performed to analyze the relation between dental plaque and tooth cariesTherewere remarkable differences among the means of DMFT and dmft from each group of children classified by children's pH value(P<001)The pH value correlated negatively with DMFT and dmft,respectivelyAs one of the caries activity test,the pH value transferring test may evaluate the severity of caries in child with mixed dentition and act as a guide for the prevention of caries in mixed dentition stage
