摘　　要：目的 :探讨幼儿龋病和口腔唾液缓冲能力、口腔内细菌数量的相关性。方法 :研究对象为上海徐汇区公立幼儿园615名3~5岁儿童,其中男童287名,女童328名。根据唾液缓冲度和口腔菌群数量分组,观察唾液缓冲度和口腔菌群数量与患龋的关系。结果:唾液缓冲度低的(<500 ppm)组患龋率明显高于中(500~1 000 ppm)和高的(>1 000 ppm)组,差异有统计学意义(P <0.001),患龋率有随口腔内细菌数量的增加而显著性升高趋势(P <0.001)。结论 :口腔内的菌群数量和唾液缓冲力是影响儿童龋病发生的重要因素。Objective: To investigate the relationship between early childhood caries(ECC) between oral buffering capacity of saliva and quantities of bacteria. Methods: A total of 615 children aged from 3-5 years were recruited from public kindergartens in Xuhui District, Shanghai as research objects, among them, there were 287 boys and 328 girl. According to the buffering capacity of saliva and oral flora number grouping, the relationship between saliva buffering degree, number of oral flora and caries were observed. Results: The low saliva buffer(<500 ppm) group had a significantly higher caries rate than the medium(500-1 000 ppm) and high(>1 000 ppm) groups, and the difference was statistically significant(P<0.001), and the caries rate increased significantly with the increase of the number of bacteria in the oral cavity(P<0.001). Conclusion: Number of oral flora and buffering capacity of saliva are the important factors of ECC.
