Toothbrushes are manufactured in different designs but it is unclear whether these differences may lead to improvement in the removal of bacterial plaque or make the toothbrushes more appealing to users. The aim of this study is to compare the efficacy of 11 toothbrushes in terms of plaque removal and their acceptance by patients.
Eleven toothbrushes were randomly assigned to one of the 12 sectors of the mouth of 48 patients. Each patient underwent one plaque recording before and after toothbrushing. Eleven sectors of the mouth were brushed by 11 different toothbrushes, while one sector was used as a control (no toothbrushing). Two questionnaires were also administered to investigate the aesthetic and comfort preference by each participant.
All 11 toothbrushes resulted in effective plaque reduction with respect to the control sector (P < 0.0001). No significant differences were found between them. Colgate Massager showed the highest score for aesthetic preference by the patients when compared with Butler 311 and Gum Super Tip 463 (P = 0.0148). Oral-B Indicator 35 exhibited the highest score in terms of comfort felt by the patients compared to Colgate Omni and Gum Technique 493 (P = 0.0095).
All of the tested toothbrushes, even though different with respect to shape and scope of function, demonstrated efficacious plaque removal.
牙刷有不同的设计，但尚不清楚这些差异是否能改善牙菌斑的清除效果，或者使牙刷对使用者更具吸引力。本研究的目的是比较11种牙刷在清除牙菌斑方面的效果以及患者对它们的接受程度。
将11种牙刷随机分配给48名患者口腔的12个区域之一。每位患者在刷牙前后各进行一次牙菌斑记录。用11种不同的牙刷分别刷洗口腔的11个区域，而其中一个区域作为对照（不刷牙）。还发放了两份问卷来调查每位参与者对美观和舒适度的偏好。
与对照区域相比，所有11种牙刷都能有效减少牙菌斑（P < 0.0001）。它们之间未发现显著差异。与巴特勒311和益齿超尖463相比，高露洁按摩牙刷在患者的美观偏好方面得分最高（P = 0.0148）。与高露洁全能牙刷和益齿技术493相比，欧乐B显示型35在患者感觉的舒适度方面得分最高（P = 0.0095）。
所有测试的牙刷，尽管在形状和功能范围方面有所不同，但都显示出有效的牙菌斑清除效果。
