目标:到目前为止,没有证据比较电动和手动牙刷在接受固定矫治器治疗的青少年中的长期疗效。该试验比较了手动牙刷与电动牙刷在短期和长期固定治疗患者中控制牙菌斑和牙龈健康的功效。
方法:这是一个随机的,平行,对照单盲临床试验,在医院环境中进行,遵循报告试验指南的合并标准.
方法:92名青少年参与者计划接受固定矫治器治疗,被随机分配到手动或电动牙刷,隐藏分配。结果测量是牙菌斑和牙龈指数和探查出血,在基线评估(在固定器具之前),one-,6个月和12个月。
结果:最终样本包括84名参与者,12-18岁(M=14.1,SD=1.93),40人(47%)使用手动牙刷,44人(52%)使用电动牙刷。干预(动力与手动牙刷)本身对于牙龈指数(GI)(95CI-0.1-0.03;P=0.26),在评估的任何时间点,菌斑指数(PI)(95CI-0.13-0.14;P=0.93)和探查出血(BoP)(95CI-0.03-0.03;P=0.98)。然而,牙周健康指标和菌斑控制显著恶化(p<0.01),在12个月的随访期内,以下是固定电器的放置位置。
结论:虽然在控制牙菌斑和牙龈健康方面没有发现手动和电动牙刷之间的差异,在接受固定正畸治疗的参与者中,两者均次优,并强调需要更多的患者支持和监测.

To-date, there is no evidence comparing the long-term efficacy of powered and manual toothbrushes in adolescents undergoing fixed appliance treatment. The trial compared the efficacy of manual versus powered toothbrush in controlling plaque and
gingival health in patients undergoing fixed treatment in respect of both the short- and long-term.
This was a randomized, parallel, controlled single-blind clinical trial, undertaken in a hospital setting, for which the consolidated standards of reporting trials guidelines were followed.
Ninety-two adolescent participants planned to undergo fixed appliance therapy, were randomly assigned to either a manual or powered toothbrush, with allocation concealment. The outcome measures were plaque and
gingival indices and bleeding on probing, assessed at baseline (prior to fixed appliance), one-, six- and 12-months.
The final sample included 84 participants, aged 12-18 (M=14.1, SD=1.93) years, with 40 (47%) were using a manual and 44 (52%) a powered toothbrush. The intervention (powered vs. manual toothbrush) itself appeared insignificant with regards to the
gingival index (GI) (95%CI -0.1 - 0.03; P=0.26), plaque index (PI) (95%CI -0.13 - 0.14; P=0.93) and bleeding on probing (BoP) (95%CI -0.03 - 0.03; P=0.98) at any of the time points assessed. However, periodontal health indicators and plaque control significantly worsened (p<0.01), over the 12-month follow-up period, following placement of the fixed appliances placement.
Whilst no differences were found between manual and powered toothbrushes in controlling plaque and
gingival health, in participants undergoing fixed orthodontic treatment, both were suboptimal and highlighted the need for greater patient support and monitoring.
