变形链球菌和远缘链球菌的分布和患病率进行了测定，从所有颊，舌和近牙面的颈部区域的牙菌斑样本，并从所有咬合部位的裂缝在40名受试者窝藏这两个物种。S.变形链球菌的检出率和检出数量均高于沙门氏菌。sobrinus。 S型检出牙数较多。mutans的数量比S.只有sobrinus 大多数牙齿都含有这两种变形链球菌，表明正相关。 两个物种的CFU数量最高的检测臼齿，与前牙的发病率最低。 S.变形链球菌在所有测试的牙齿上相对相似，而S.与前牙相比，磨牙上的sobrinus相对较高。 S. 和S.发现sobrinus以几乎相等的数量定殖于颊表面。 在所有其他表面上，S。与S. sobrinus。 S的相对比例无显著差异。和S.在健全的，腐烂的或填充的牙齿表面之间的sobrinus。
The distribution and prevalence of Streptococcus mutans and Streptococcus sobrinus were determined in plaque samples from the cervical areas of all buccal, lingual and approximal tooth surfaces and from the fissures of all occlusal sites in 40 subjects harboring both species. S. mutans was detected more often and in higher numbers than S. sobrinus. There were more teeth detected with S. mutans only than with S. sobrinus only. Most teeth harbored both of these mutans streptococci species, indicating a positive association. The highest numbers of CFU for both species were detected on the molars, with the lowest incidence on the anterior teeth. The presence of S. mutans was relatively similar on all teeth tested, while the presence of S. sobrinus was relatively higher on the molars compared to the anterior teeth. S. mutans and S. sobrinus were found to colonize the buccal surfaces in almost equal numbers. On all other surfaces, S. mutans was detected more frequently or in higher numbers compared to S. sobrinus. No significant differences could be found in the relative proportions of S. mutans and S. sobrinus between sound, decayed or filled tooth surfaces.
