The Colgate Precision Compact, soft texture toothbrush and the Oral-B 35 toothbrush were compared using a laboratory device designed to simulate clinical toothbrushing motions and pressures. The toothbrushing time was sixty seconds for each vertical or horizontal toothbrushing sequence, for each of the three brushing weights tested (250, 500 or 750 g). Interproximal access efficacy (IAE) was determined by measuring the maximum width of the brushing stroke on pressure-sensitive paper placed around simulated anterior or posterior teeth. Twenty-four toothbrushes of each design were evaluated for each toothbrushing motion, tooth shape and toothbrushing weight. Using the vertical toothbrushing motion on anterior teeth, IAE means for the Colgate Precision Compact toothbrush were significantly higher (p < 0.001) than the Oral-B 35 toothbrush at 250 and 750 g of brushing weight. With vertical toothbrushing across posterior-shaped teeth, IAE values for the Colgate Precision Compact toothbrush were significantly higher (p < 0.001) than the Oral-B 35 toothbrush at each of the 250, 500 and 750 g brushing weights tested. With horizontal toothbrushing motions, the Colgate Precision Compact toothbrush had significantly higher (p < 0.001) IAE means, compared to the Oral-B 35 toothbrush, on both anterior and posterior tooth shapes and at each of the brushing weights tested. When all factors tested were combined, the total IAE for the Colgate Precision Compact toothbrush was significantly superior (p < 0.001) to the Oral-B 35 toothbrush.
使用一种旨在模拟临床刷牙动作和压力的实验室装置，对高露洁精密紧凑型软质地牙刷和欧乐-B 35型牙刷进行了比较。对于测试的三种刷牙重量（250、500或750克）中的每一种，每次垂直或水平刷牙序列的刷牙时间均为60秒。通过测量放置在模拟前牙或后牙周围的压敏纸上刷牙行程的最大宽度来确定牙间隙清洁效果（IAE）。对于每种刷牙动作、牙齿形状和刷牙重量，对每种设计的24支牙刷进行了评估。在前牙上使用垂直刷牙动作时，在250克和750克刷牙重量下，高露洁精密紧凑型牙刷的IAE平均值显著高于欧乐-B 35型牙刷（p < 0.001）。在横跨后牙形状的牙齿进行垂直刷牙时，在测试的250、500和750克每种刷牙重量下，高露洁精密紧凑型牙刷的IAE值均显著高于欧乐-B 35型牙刷（p < 0.001）。在水平刷牙动作中，与欧乐-B 35型牙刷相比，高露洁精密紧凑型牙刷在前牙和后牙形状以及测试的每种刷牙重量下的IAE平均值均显著更高（p < 0.001）。当所有测试因素综合起来时，高露洁精密紧凑型牙刷的总IAE显著优于欧乐-B 35型牙刷（p < 0.001）。
