Abstract

PURPOSE

Recently, a new experimental battery-powered toothbrush was developed as a second generation to Crest SpinBrush. The brush head of this new prototype toothbrush (Crest SpinBrush Pro) incorporates a dual moving head design with one oscillating and the other translating back and forth. The objective of this study was to compare the plaque removal efficacy of a positive control manual toothbrush (Oral-B Cross Action) to this prototype power toothbrush following a repeated single use study design. In addition, this paper reports the results of a study examining the relative plaque removal efficacy of the positive control manual toothbrush to seven representative manual toothbrushes.

METHODS

This study was a randomized, controlled, examiner-blind, four-period crossover design, which examined plaque removal with the two toothbrushes following a single use in 40 subjects. Plaque was scored before and after brushing using the Turesky Modification of the Quigley-Hein Index.

RESULTS

Baseline plaque scores were 2.61 and 2.66 for the prototype power toothbrush and control toothbrush treatment groups, respectively. With respect to all surfaces examined, the prototype power toothbrush delivered an adjusted (via analysis of covariance) mean difference between baseline and post-brushing plaque scores of 0.98 while the control toothbrush delivered an adjusted mean difference of 0.74. The experimental toothbrush group, on average, had a 32.8% larger plaque removal score than the control toothbrush. These results were statistically significant (P < 0.001). Similar results were observed on buccal and lingual surfaces. In addition, results from the study comparing manual toothbrushes showed that the positive control manual toothbrush had higher plaque removal scores compared to seven representative manual toothbrushes. The plaque removal score differences reached statistical significance for five of the seven toothbrushes.

摘要

目的

最近，一款新型实验性电池供电牙刷作为佳洁士旋转式牙刷的第二代产品被研发出来。这款新型原型牙刷（佳洁士旋转式牙刷专业版）的刷头采用了双动头设计，一个刷头进行振荡运动，另一个刷头则前后平移。本研究的目的是在重复单次使用研究设计之后，比较阳性对照手动牙刷（欧乐-B多角度清洁牙刷）与这款原型电动牙刷的牙菌斑清除效果。此外，本文还报告了一项研究的结果，该研究考察了阳性对照手动牙刷与七款代表性手动牙刷的相对牙菌斑清除效果。

方法

本研究采用随机、对照、检查者盲法、四阶段交叉设计，在40名受试者单次使用这两款牙刷后检查牙菌斑清除情况。使用Turesky对Quigley-Hein指数的修正版在刷牙前后对牙菌斑进行评分。

结果

原型电动牙刷治疗组和对照牙刷治疗组的基线牙菌斑评分分别为2.61和2.66。对于所有检查的表面，原型电动牙刷在基线和刷牙后牙菌斑评分之间的调整（通过协方差分析）平均差异为0.98，而对照牙刷的调整平均差异为0.74。实验牙刷组平均牙菌斑清除得分比对照牙刷高32.8%。这些结果具有统计学意义（P < 0.001）。在颊面和舌面也观察到了类似结果。此外，比较手动牙刷的研究结果表明，阳性对照手动牙刷与七款代表性手动牙刷相比，具有更高的牙菌斑清除得分。七款牙刷中有五款的牙菌斑清除得分差异具有统计学意义。
