The levels of salivary Streptococcus mutans and lactobacilli and caries experience were studied in 113 teenagers and 163 adults. The study population consisted of 82 mother-child and 73 father-child pairs. The number of decayed, missing, and filled tooth surfaces (DMFS) was eightfold higher in adults than in teenagers (56.4 +/- 22.8 vs. 7.3 +/- 6.7). The percentage distribution of the level of salivary S. mutans and lactobacilli was approximately the same in both groups. The mean number of DMFS increased with increasing levels of salivary S. mutans and lactobacilli, the correlation being highly significant both in teenagers and adults. There was a significant correlation of the DMFS indices in the mother-child pairs (r = 0.364), but the correlation was not significant in the father-child pairs (r = 0.138). The salivary level of S. mutans was higher in the children of mothers with high DMFS values compared to the children of mothers with low DMFS values.
对113名青少年和163名成年人的唾液变形链球菌和乳杆菌水平以及龋齿情况进行了研究。研究对象包括82对母子和73对父子。成年人的龋失补牙面数（DMFS）比青少年高八倍（56.4±22.8对7.3±6.7）。两组唾液变形链球菌和乳杆菌水平的百分比分布大致相同。DMFS的平均数随唾液变形链球菌和乳杆菌水平的升高而增加，青少年和成年人中的相关性均高度显著。母子对中DMFS指数存在显著相关性（r = 0.364），但父子对中的相关性不显著（r = 0.138）。与DMFS值低的母亲的孩子相比，DMFS值高的母亲的孩子唾液中的变形链球菌水平更高。
