中文摘要：

目的研究对比主观感觉因素与改良Bass刷牙法对刷牙效果的影响。方法选择非口腔专业大一学生80名，29名男生，51名女生，平均年龄20岁，随机分为4组，对比习惯刷牙法（CM），习惯加主观感觉法（舔舐牙面有舔玻璃样感觉）（CSM），Bass刷牙法（BM），主观感觉和改良Bass结合法刷牙（BCSM）对上下前牙和前磨牙菌斑指数的影响。结果主观感觉因素刷牙法和Bass刷牙法结合效果最佳，差异具有显著统计学意义（P〈0．01）；习惯法加主观感觉法对牙菌斑的清除效果明显优于习惯法（P〈0．05），但不及Bass刷牙法。结论主观感觉法和改良Bass结合法是最佳的刷牙方法。

英文摘要：

Objective To study the effect of subjective sensation factor and the Bass technique on brushing. Methods Eighty non-dental, freshman students （29 males and 51 females with an average age of 20 years） were selected and divided into four groups randomly. In the research a comparison was made between the different effects of four toothbrushing methods for of plaque index on the upper and lower anterior and premolars： the conventional toothbrushing method （CM）, the conventional toothbrushing method plus subjective sensation （having the sensation of lick the glass when licking tooth surface） （CSM）, the Bass method （BM）, the combination of the BM and the CSM （BCSM）. Results BCSM was by far the most effective in removing supragingival plaque of all the four methods （ P 〈 0.01 ）. CSM was significantly better than CM in removing plaque （P 〈 0.05 ）. BM was significantly better than CSM in that effect （P 〈 0. 01 ）. Conclusion BCSM is significantly superior to the other three methods in plaque removal.
