To evaluate and compare the efficacy of a marketed oscillating-rotating electric rechargeable toothbrush to a marketed sonic toothbrush in the reduction of gingivitis and plaque over an 8-week period.
This was a randomized, examiner-blind, parallel group, eight-week study. Subjects with presence of mild-to-moderate plaque and gingivitis received an oral examination and were evaluated for baseline gingivitis (Modified Gingival Index; MGI), gingival bleeding (Gingival Bleeding Index; GBI), and plaque (Rustogi Modified Navy Plaque Index). Qualified subjects were randomly assigned to an entry-level oscillating-rotating electric rechargeable brush handle (Oral-B® PRO 1000, D16U) with a round brush head with angled bristles (Oral-B® CrossAction, EB50) or a premium sonic brush (Philips Sonicare® Diamond Clean Toothbrush with AdaptiveClean brush head). One hundred and fifty subjects were instructed to brush twice daily with their assigned brush and a fluoride dentifrice for eight weeks before returning for an oral examination and gingivitis and plaque evaluations. The same methods were used at baseline and Week 8 for all evaluations.
One hundred and forty-eight subjects completed the study, 74 in each group. After eight weeks of use, both brushes reduced MGI, GBI, total number of bleeding sites, whole mouth plaque, gingival margin plaque, and proximal plaque (p < 0.001 for each). The oscillating-rotating brush provided statistically significantly greater reductions than the sonic brush for all gingivitis measures, with a 34.8%, 48.4%, and 42.6% greater reduction for MGI, GBI, and number of bleeding sites, respectively, after eight weeks of use (p < 0.001 for each). Significantly greater whole mouth (26.2%) and proximal (38.5%) plaque reductions were also demonstrated at Week 8 for the oscillating-rotating brush versus the sonic brush (p < 0.001).
The entry-level oscillating-rotating brush performed better than the premium sonic brush in the reduction of plaque and gingivitis in this eight-week randomized and examiner-blind study.
评估并比较一款市售的振荡旋转电动可充电牙刷与一款市售的声波牙刷在8周时间内减少牙龈炎和牙菌斑方面的功效。
这是一项随机、检查者盲法、平行组、为期8周的研究。存在轻度至中度牙菌斑和牙龈炎的受试者接受了口腔检查，并对基线牙龈炎（改良牙龈指数；MGI）、牙龈出血（牙龈出血指数；GBI）和牙菌斑（Rustogi改良海军牙菌斑指数）进行了评估。合格受试者被随机分配到一个入门级振荡旋转电动可充电刷柄（欧乐B® PRO 1000，D16U），配有一个带斜刷毛的圆形刷头（欧乐B® CrossAction，EB50），或一个高端声波牙刷（飞利浦声波震动牙刷钻石亮白型配自适应清洁刷头）。150名受试者被指示每天用分配的牙刷和含氟牙膏刷牙两次，持续8周，然后返回进行口腔检查以及牙龈炎和牙菌斑评估。在基线和第8周时，所有评估均采用相同方法。
148名受试者完成了研究，每组74名。使用8周后，两种牙刷均降低了MGI、GBI、出血部位总数、全口牙菌斑、龈缘牙菌斑和邻面牙菌斑（每项p < 0.001）。对于所有牙龈炎指标，振荡旋转牙刷在统计学上比声波牙刷有更显著的降低，使用8周后，MGI、GBI和出血部位数量分别降低了34.8%、48.4%和42.6%（每项p < 0.001）。在第8周时，振荡旋转牙刷与声波牙刷相比，全口牙菌斑（26.2%）和邻面牙菌斑（38.5%）的减少也更显著（p < 0.001）。
在这项为期8周的随机、检查者盲法研究中，入门级振荡旋转牙刷在减少牙菌斑和牙龈炎方面比高端声波牙刷表现更好。
