对78名4岁儿童从15个月大起每隔4个月检查一次变形链球菌，以记录龋齿和唾液样本。对唾液样本进行了突变链球菌的分析，包括变形链球菌、远缘链球菌和乳杆菌。结果表明，儿童中发现变形链球菌的时间越早，患龋率越高。在2岁时定居的儿童中，89%的儿童经历过龋齿，平均DFS为5.0，而未定居的4岁儿童中，25%的儿童平均DFS为0.3。变形链球菌是优势种。远缘链球菌通常与变形链球菌混合存在，但在2名儿童中仅检出远缘链球菌。与只有变形链球菌的儿童相比，有更多种类的儿童有更多的突变链球菌总数，并且有更高的龋患率趋势。
Seventy-eight 4-year-old children, examined earlier for the presence of mutans streptococci at 4-month intervals from 15 months of age, were recalled for recording of dental caries and salivary sampling. The saliva samples were analysed for the presence of mutants streptococci, including the species Streptococcus mutans and Streptococcus sobrinus and lactobacilli. The results showed that the earlier the mutans streptococci had been detected in the children, the higher the caries experience. Eight-nine percent of the children colonized at 2 years of age had experienced caries and had a mean dfs of 5.0 compared with 25% of the non-colonized 4-year-olds with a mean dfs of 0.3. S. mutans was the predominant species. S. sobrinus was usually found in combination with S. mutans, except in 2 children where S. sobrinus was the only species detected. More children with multiple species had higher numbers of total mutants streptococci and a tendency to higher caries prevalence than children with only S. mutans.
