Primary reservoirs of Streptococcus mutans were identified in a group of 21 adults with intact dentitions and good oral hygiene by obtaining multiple plaque samples from all available tooth surfaces. Routine cultural methods and a rapid plate scoring method employing a 7-point ordinal scale were used to assess S. mutans levels. Oral hygiene status (DI-S) and caries experience (DMFT and DMFS) were determined clinically. Primary S. mutans reservoirs (high scores) were restricted essentially to the posterior interproximal areas and occasionally in the occlusal pits and fissures of partially erupted mandibular third molars. An anterior to posterior gradient of increasing S. mutans scores was observed for interproximal sites. Oral hygiene scores correlated poorly with DMFT, DMFS and the S. mutans scores obtained for different anatomic locations.
通过从所有可用牙面获取多个菌斑样本,在一组21名牙列完整且口腔卫生良好的成年人中确定了变形链球菌的主要储存部位。采用常规培养方法和一种使用7分序数尺度的快速平板评分方法来评估变形链球菌水平。临床确定口腔卫生状况(DI-S)和龋病经历(DMFT和DMFS)。变形链球菌的主要储存部位(高分)基本上局限于后牙邻面区域,偶尔也见于部分萌出的下颌第三磨牙的咬合窝和裂隙。观察到邻面部位变形链球菌评分从前向后呈递增梯度。口腔卫生评分与DMFT、DMFS以及不同解剖部位的变形链球菌评分之间相关性较差。
