婴幼儿龋口腔致龋菌活性的研究

摘要

Objective:To comparatively analyze the caries activity among early childhood caries,severe early childhood caries and caries free children. Methods:A total of 289 children aged 3-5 years in three kindergartens in Nanjing were examined for dental caries and caries activity test. The parents were investigated and the results were statistically analyzed. Results:The caries prevalence rate of primary teeth was 47.8%,the prevalence of SECC was 20.4%. Cariostat value was significantly correlated with dmft and dmfs,and had statistical differences between the three groups. Sweet food/drink before sleep and Cariostat value was significantly related to the caries. Conclusions:The cariogenic bacteria activity of early childhood caries can reflect the severity of caries.%目的:对婴幼儿龋、重度婴幼儿龋及无龋患儿口腔致龋菌活性进行比较分析.方法:对南京市三所幼儿园共289名3~5岁儿童进行口腔冠龋检查,使用龋态-Cariostat龋病易感性检测试剂盒进行龋活性试验,并对家长进行问卷调查,对结果进行统计分析.结果:儿童乳牙患龋率为47.8%,重度婴幼儿龋患病率为20.4%;婴幼儿龋、重度婴幼儿龋及无龋患儿三组间Cariostat值具有统计学差异;相关分析显示龋活跃性检测值与龋均(dmft)、龋面均(dmfs)显著正相关;单因素分析显示睡前吃甜点或喝甜饮料、龋活跃性检测值与儿童乳牙患龋有明显相关.结论:婴幼儿口腔致龋菌活性可反映龋病的严重程度.
