A pre-brushing dental rinse, based on the principle of non-specific removal and modification of dental plaque by detergent action, was studied. The rinse had previously been shown to have the ability to remove a limited amount of plaque without intervention of the toothbrush. In this study, the effect of the rinse on routine plaque control was evaluated over a 3-week period. The protocol sought to minimize the Hawthorne effect. A regimen involving use of the rinse prior to toothbrushing produced a significant decrease in mean plaque score of 50% compared to baseline. A normal oral hygiene regimen (i.e., toothbrushing without the pre-brushing rinse) resulted in a non-significant decrease in plaque area score of 11%. The difference in plaque reduction between the two regimens was significant at p less than .001.
研究了一种基于洗涤剂作用非特异性去除和改变牙菌斑原理的刷牙前口腔冲洗液。先前已证明该冲洗液在不借助牙刷干预的情况下能够去除有限量的牙菌斑。在本研究中，在3周的时间内评估了该冲洗液对常规牙菌斑控制的效果。该方案旨在尽量减少霍桑效应。与基线相比，在刷牙前使用该冲洗液的方案使平均菌斑评分显著降低了50%。正常的口腔卫生方案（即不使用刷牙前冲洗液的刷牙）导致菌斑面积评分非显著降低了11%。两种方案在菌斑减少方面的差异在p小于0.001时具有显著性。
