摘　　要：目的　本文通过研究两种刷牙法的刷牙压力及牙面清洁效果 ,为刷牙指导提供科学的依据。方法　将 1 0 6名 1 3～ 1 4岁学生随机分为两组 ,在刷牙测定仪的监测下 ,一组以旋转法、另一组以短距离横刷法刷牙。分 1 2个牙区记录刷牙前后的菌斑指数和刷牙压力 ,每 1牙区的刷牙时间为 1 5.6S。结果　短距离横刷法较旋转法更易去除龈缘区菌斑 (P <0 .0 0 1 ) ,而前者的刷牙压力小于后者 (P <0 .0 0 1 )。结论　可以认为短距离横刷法是更佳的刷牙方法。Objective In order to offer scientific toothbrushing instruction, the toothbrushing force and plaque removing efficiency of two brushing methods were compared. Method 106 thirteen to fourteen year old students were randomly divided into two groups. One group brushed their teeth with roll method, the other with scrub method. The whole mouth were divided into 12 areas and each area was brushed 15.6 seconds. A strain gauge recorded the brushing force in both groups. One examiner recorded all students' O'Leary Plaque Index before and after brushing. Results Though the brushing force of scrub group is lower than roll group, the former was more efficient in removing plaque. Conclusion The Scrub method may be regarded as the more effici
