The effectiveness of plaque removal using two brushes with the Bass technique and two with the Roll method was compared in a group of 38 junior dental students using a crossover experimental design. The Bass technique was superior to the Roll method in cleaning the tooth tissue adjacent to the gingival tissue on the lingual and facial aspects, but no significant differences were found in the overall effectiveness. Cleaning of all tooth surfaces was at an unacceptable level and it is concluded that efficient tooth cleaning is not achieved by detailed instruction at a single visit including a demonstration of competence by the subject and the issue of written instructions. Repetition of the instruction within 3 weeks did not achieve a higher standard of plaque removal.
采用交叉实验设计，在38名低年级牙科学生中比较了使用两种巴氏刷牙法牙刷和两种旋转刷牙法牙刷去除牙菌斑的效果。在清洁舌侧和颊侧牙龈组织相邻的牙齿组织方面，巴氏刷牙法优于旋转刷牙法，但在总体效果上未发现显著差异。所有牙齿表面的清洁程度都处于不可接受的水平，得出的结论是，通过单次就诊时的详细指导（包括受试者展示操作能力和发放书面说明）并不能实现有效的牙齿清洁。在3周内重复指导并未达到更高的牙菌斑清除标准。
