The Colgate Plus Rippled Bristles toothbrush and the Oral-B 40 toothbrush were compared using a laboratory device designed to stimulate clinical toothbrushing motions and pressures and measure interproximal access efficacy. The toothbrushing time was sixty seconds for each vertical or horizontal toothbrushing sequence and for each of the three brushing weights tested (250, 500 or 750 grams). Interproximal access efficacy 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. With vertical toothbrushing motions, the Colgate Rippled toothbrush had significantly higher (p < 0.001) interproximal access efficacy means compared to the Oral-B 40 toothbrush, on anterior tooth shapes at the 250 and 500 grams of brushing weights and on posterior tooth shapes at all of the brushing weights tested. Using the horizontal toothbrushing motion on anterior teeth, the interproximal access efficacy for the Colgate Rippled toothbrush was significantly higher (p < 0.05) than the Oral-B 40 toothbrush at 250 and 500 grams of brushing weights. With horizontal toothbrushing across posterior-shaped teeth, interproximal access efficacy values for the Colgate Rippled toothbrush were significantly higher (p < 0.05-0.001) than the Oral-B 40 toothbrush at all of the brushing weights tested. When the various parameters tested were combined for all brushing weights, both brushing motions or both tooth shapes, interproximal access efficacy means for the Colgate Rippled toothbrush were higher (p < 0.05-0.001) than the combined means for the Oral-B toothbrush. When all factors tested were combined, total interproximal access efficacy for the Colgate Rippled toothbrush was significantly superior (p<0.001) to the Oral-B 40 toothbrush.
使用一种实验室装置对高露洁波纹刷毛牙刷和欧乐 - B 40 牙刷进行了比较，该装置旨在模拟临床刷牙动作和压力，并测量牙间隙清洁效果。每个垂直或水平刷牙序列的刷牙时间为 60 秒，对测试的三种刷牙力度（250、500 或 750 克）中的每一种都是如此。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。对于每种刷牙动作、牙齿形状和刷牙力度，对每种设计的 24 支牙刷进行了评估。在垂直刷牙动作中，在 250 克和 500 克刷牙力度下的前牙形状以及在所有测试的刷牙力度下的后牙形状上，高露洁波纹牙刷的牙间隙清洁效果均值显著高于（p < 0.001）欧乐 - B 40 牙刷。在前牙上使用水平刷牙动作时，在 250 克和 500 克刷牙力度下，高露洁波纹牙刷的牙间隙清洁效果显著高于（p < 0.05）欧乐 - B 40 牙刷。在横跨后牙形状进行水平刷牙时，在所有测试的刷牙力度下，高露洁波纹牙刷的牙间隙清洁效果值显著高于（p < 0.05 - 0.001）欧乐 - B 40 牙刷。当将所有测试参数针对所有刷牙力度、两种刷牙动作或两种牙齿形状进行综合时，高露洁波纹牙刷的牙间隙清洁效果均值高于（p < 0.05 - 0.001）欧乐 - B 牙刷的综合均值。当将所有测试因素综合起来时，高露洁波纹牙刷的总牙间隙清洁效果显著优于（p < 0.001）欧乐 - B 40 牙刷。
