A comparative study using a crossover experimental construction was made of the effectiveness of brushes containing 6/10 nylon filaments of 0.132 mm mean diameter using a Bass technique with those containing filaments of the same type of nylon but 0.280 mm diameter. Each type of brush was used for a 2-week period. Even though the finer filament brushes contained more than three times as many filaments, they were inferior in cleaning achievement to the brushes with the broader filaments. The difference was particularly marked on the facial aspect, but was largely nullified lingually. The effectiveness of the Bass technique in the gingival zone demonstrated in a previous investigation when brushes containing filaments of 0.18 and 0.20 mm were used, was not found in this investigation. It is concluded that filament diameter is critical in achieving effective cleaning using the Bass technique.
采用交叉实验设计进行了一项对比研究，比较了使用巴斯刷牙法时，平均直径为0.132毫米的6/10尼龙刷毛牙刷和相同类型但直径为0.280毫米的尼龙刷毛牙刷的清洁效果。每种类型的牙刷使用两周。尽管细丝刷毛牙刷的刷毛数量是粗丝刷毛牙刷的三倍多，但在清洁效果上却不如粗丝刷毛牙刷。这种差异在面部尤为明显，但在舌侧基本消失。在之前的一项研究中，使用直径为0.18毫米和0.20毫米刷毛的牙刷时，巴斯刷牙法在牙龈区域显示出有效性，但在本次研究中未发现这一现象。得出的结论是，在使用巴斯刷牙法实现有效清洁方面，刷毛直径至关重要。
