对日本356名0-2岁儿童的龋病患病率、唾液中变形链球菌的数量和种类分布进行了两次检查，每隔1年进行一次。 没有变形链球菌分离出predentate儿童。 变形链球菌检出率和患龋率随年龄增长而增高。 从39.9%的受试者中分离出变形链球菌。 大多数分离株被鉴定为变形链球菌。 变形链球菌浓度与萌出牙数相关（r = 0.339）。 此外，唾液中变形链球菌浓度与下一年患龋率的相关性（r = 0.465）比首次评估唾液中变形链球菌浓度时的相关性（r = 0.368）更密切。 第一年没有龋齿但携带变形链球菌的儿童在第二年的龋齿患病率显著高于既没有龋齿也没有变形链球菌的儿童。 这些结果表明，变形链球菌的建立与儿童早期龋齿的发生有关。
The prevalence of caries and the number and species distribution of salivary mutans streptococci in 356 children (aged 0-2 yr old) in Japan were examined twice at an interval of 1 yr. No mutans streptococci were isolated from the predentate children. The detection rate of mutans streptococci and the prevalence of caries increased with age. Mutans streptococci were isolated from 39.9% of the subjects. The majority of isolates were identified as Streptococcus mutans. The concentration of mutans streptococci correlated with the number of erupted teeth (r = 0.339). In addition, the concentration of mutans streptococci was more closely correlated to the caries prevalence of the next year (r = 0.465) than that of the year when the salivary concentration of mutans streptococci was first evaluated (r = 0.368). The children who had no caries but harbored mutans streptococci in the first year showed significantly higher caries prevalence in the next year than did the children with neither caries nor mutans streptococci. These results indicate that the establishment of mutans streptococci is associated with caries initiation in early childhood.
