背景：最近推出了一种新的电池电动牙刷，其设计与其他电动牙刷有着根本的不同。新牙刷有一个动力振荡圆头和第二个动力头，来回平移。本研究比较了手动牙刷的菌斑去除效果，这种新的电动牙刷。方法：这种随机，对照，检查员屏蔽，四个阶段的交叉研究检查菌斑去除与两种牙刷后，在40个科目的单次使用。菌斑得分刷牙前和刷牙后1和3分钟使用Turesky修改的Quigley-Hein index.Results：基线菌斑得分分别为2.98之前使用电动牙刷和2.99之前使用手动牙刷。电动牙刷在刷牙1分钟后提供了0.61的协方差调整平均菌斑评分变化，在刷牙3分钟后提供了0.93的协方差调整平均菌斑评分变化。手动牙刷的调整后平均变化分别为0.43和0.62。治疗组间差异有统计学意义（P
Background: A new battery-powered toothbrush with a fundamentally different design than other powered toothbrushes has recently been introduced. The new toothbrush has a powered oscillating round head and a second powered head that translates back and forth. This study compared the plaque removal efficacy of a manual toothbrush to this new powered toothbrush.Methods: This randomized, controlled, examiner-masked, four-period cross-over study examined plaque removal with the two toothbrushes following a single use in 40 subjects. Plaque was scored before brushing and after 1 and 3 minutes of brushing using the Turesky modification of the Quigley-Hein index.Results: Baseline plaque scores were 2.98 prior to using the powered toothbrush and 2.99 prior to using the manual toothbrush. The powered toothbrush delivered a covariance-adjusted mean plaque score change from baseline of 0.61 after 1 minute of brushing and 0.93 after 3 minutes of brushing. The adjusted mean changes for the manual toothbrush were 0.43 and 0.62, respectively. The differences between treatment groups were statistically significant (P
