A two by two factorial designed study was conducted to compare the effectiveness of the newly designed 'Concept 45 degrees' toothbrush on removal of dental plaque, to a standard conventional toothbrush using either the roll technique or the Bass technique of toothbrushing. One hundred male soldiers, aged 21-22 years were stratified into four balanced groups according to baseline plaque scores obtained from a pretest period. They received oral prophylaxis and were randomly assigned into one of the four experimental groups: (a) standard conventional toothbrush with the roll technique, (b) standard conventional toothbrush with the Bass technique, (c) the 'Concept 45 degrees' toothbrush with the roll technique, and (d) the 'Concept 45 degrees' with the Bass technique. The results showed that the 'Concept 45 degrees' toothbrush using the Bass technique removed dental plaque more effectively than the standard conventional toothbrush with either technique.
开展了一项二乘二析因设计研究，以比较新设计的“45度概念”牙刷与使用旋转刷牙法或巴氏刷牙法的标准传统牙刷在清除牙菌斑方面的效果。100名年龄在21至22岁的男性士兵根据预测试期获得的基线菌斑评分被分层为四个均衡组。他们接受了口腔预防治疗，并被随机分配到四个实验组之一：（a）使用旋转刷牙法的标准传统牙刷，（b）使用巴氏刷牙法的标准传统牙刷，（c）使用旋转刷牙法的“45度概念”牙刷，以及（d）使用巴氏刷牙法的“45度概念”牙刷。结果表明，使用巴氏刷牙法的“45度概念”牙刷比使用任何一种刷牙法的标准传统牙刷更有效地清除牙菌斑。
