The primary objective was to determine, based on the available published evidence, the efficacy of powered toothbrushing following a brushing exercise and secondary to what magnitude this effect is dependent on the plaque index score, power supply and mode of action.
The PubMed-MEDLINE and Cochrane CENTRAL databases were searched through and up to August 2014 to identify appropriate studies. The outcome measurement was the weighted mean (WM) percentage plaque score reduction of a full-mouth assessment following subject brushing.
The search yielded 2420 titles and abstracts. Ultimately, 58 articles with 146 brushing exercises as separate legs were selected. The overall effect of a powered brushing exercise provides a 46% WM plaque score reduction. One hundred and six experiments provided data as assessed according to the Quigley and Hein plaque index. The WM reduction from baseline in plaque scores was 36%. A WM plaque score reduction of 65% was observed in 39 experiments using the Navy plaque index. Subanalysis on power supply and mode of action showed WM plaque score reductions ranging from 33% up to 71% depending on plaque index score.
The efficacy in plaque removal following a brushing exercise using a powered toothbrush provides a WM plaque score reduction of 46% on average, with a range of 36-65% dependent on the index scale to score plaque. The available evidence indicates that the power supply (rechargeable or replaceable battery), mode of action, as well as brushing duration and type of instructions are factors which contribute to the variation in the observed efficacy.
主要目标是根据现有已发表的证据，确定刷牙练习后电动牙刷的功效，其次确定这种效果在何种程度上取决于菌斑指数评分、电源和作用方式。
检索了截至2014年8月的PubMed-MEDLINE和Cochrane CENTRAL数据库，以识别合适的研究。结局测量指标是受试者刷牙后全口评估的加权平均（WM）菌斑评分降低百分比。
检索得到2420个标题和摘要。最终，选择了58篇文章，其中包含146次作为独立研究分支的刷牙练习。电动刷牙练习的总体效果是使WM菌斑评分降低46%。106项实验根据Quigley和Hein菌斑指数进行评估并提供了数据。菌斑评分从基线降低的WM值为36%。在使用海军菌斑指数的39项实验中，观察到WM菌斑评分降低了65%。根据电源和作用方式进行的亚分析表明，根据菌斑指数评分，WM菌斑评分降低幅度在33%至71%之间。
使用电动牙刷进行刷牙练习后，去除菌斑的功效平均使WM菌斑评分降低46%，根据菌斑评分量表的不同，降低幅度在36%至65%之间。现有证据表明，电源（可充电或可更换电池）、作用方式以及刷牙持续时间和指导类型是导致观察到的功效存在差异的因素。
