Intraindividual variations in the mutans streptococci measured by Strip mutans, in a 1-day and a 5-day period, as well as the effect of toothbrushing, were investigated. 30 subjects participated, and their levels of salivary mutans were estimated by a scale containing four steps. With the exception of three comparisons, time intervals of different lengths did not cause a deviation of more than one step. Comparisons made before and after toothbrushing yielded the same score in 22 cases, whereas two subjects showed a discrepancy of two steps. Clearly, in a short-term perspective, variations can certainly be found, but more pronounced discrepancies are rare.
通过变形链球菌试纸条法测定了个体在1天和5天内变形链球菌的个体内变异情况，以及刷牙的影响。30名受试者参与了研究，他们的唾液变形链球菌水平通过一个包含四个等级的量表进行评估。除了三次比较外，不同时长的时间间隔导致的偏差不超过一个等级。刷牙前后的比较中，22例受试者得分相同，而两名受试者的得分相差两个等级。显然，从短期来看，变异确实存在，但更明显的差异很少见。
