摘要
目的观察不同龋患幼儿唾液乳酸杆菌感染水平的差异,评价Dentocult LB法作为龋活跃性检测方法的效果。方法以深圳市375名2～4岁幼儿为研究对象,进行口腔检查,计算患龋率、龋失补牙数(dmft)、龋失补牙面(dmfs)、龋蚀指数(CSI),采用Dentocult LB法检测唾液乳酸杆菌,记录分度值。结果幼儿Dentocult LB分度间患龋率,dmft,dmfs,CSI差异均有统计学意义,Dentocult LB分度与dmft,dmfs,CSI呈高度正相关,Dentocult LB各分度在不同性别、不同年龄间的分布差异无统计学意义。结论不同龋患幼儿唾液乳酸杆菌感染水平差异有统计学意义。Dentocult LB分度能较真实地反映幼儿乳牙龋病的发生状况,是一种可靠的龋活跃性检测方法 。
Objective To study the variance of lactobacilli in saliva among children with different caries status,and evaluate the effect of Dentocult LB as a caries activity test （CAT）.Methods The caries status in 375 children aged 2 to 4 was examined.Caries incidence,dmft,dmfs and CSI were calculated;lactobacilli in saliva were detected with Dentocult LB and the data was statistically analyzed.Results Significant statistical differences of caries status were found among different Dentocult LB grades,which were highly correlated with dmft,dmfs and CSI.The distributing of Dentocult LB grades had no statistical difference among different genders or ages.Conclusion There are significant differences of lactobacilli in saliva among children with different caries status.Dentocult LB method,which can reflect the existing caries status of primary teeth effectively,is a reliable method as a CAT.
