To assess extrinsic stain removal efficacy of a power toothbrush and a dental prophylaxis followed by the use of a standardized American Dental Association (ADA) reference manual toothbrush.
This was a randomized, positive-controlled, examiner-blind, parallel group, two-week study. A Lobene stain examination was performed at baseline. Subjects were randomized to one of two treatment groups: Group 1: Oral-B Vitality Pro White power toothbrush or Group 2: Subjects receiving a dental prophylaxis then using a standardized ADA reference manual toothbrush. Subjects were instructed to brush their teeth with the assigned toothbrush and a fluoride dentifrice in front of a mirror twice per day for 2 minutes. Stain was reassessed following 2 weeks of brushing.
A significant reduction (p <0.001) in mean Lobene composite scores after 2 weeks was found for Group 1 (90.6%) and Group 2 (94.4%). Both groups also showed a significant reduction (p <0.001) in extent and intensity scores. There was no significant group difference in reduction in mean Lobene composite scores (p>0.1).
The Oral-B Vitality Pro White power toothbrush showed effective stain removal at a level similar to receiving an oral prophylaxis followed by the use of an ADA reference manual toothbrush.
In this small study the Oral-B Vitality Pro White power toothbrush achieved statistically significant stain removal between dental visits.
评估一款电动牙刷和一次牙齿预防性清洁（之后使用标准化的美国牙科协会（ADA）参考手动牙刷）对外源性色斑的清除效果。
这是一项随机、阳性对照、检查者盲法、平行组、为期两周的研究。在基线时进行洛贝内色斑检查。受试者被随机分为两个治疗组之一：第1组：欧乐B活力亮白专业型电动牙刷；或第2组：接受牙齿预防性清洁，然后使用标准化ADA参考手动牙刷的受试者。指导受试者每天在镜子前用指定的牙刷和含氟牙膏刷牙两次，每次2分钟。刷牙2周后重新评估色斑情况。
第1组（90.6%）和第2组（94.4%）在刷牙2周后，洛贝内综合平均得分均显著降低（p<0.001）。两组的范围和强度得分也均显著降低（p<0.001）。两组在洛贝内综合平均得分降低方面无显著差异（p>0.1）。
欧乐B活力亮白专业型电动牙刷在清除色斑方面效果显著，与接受牙齿预防性清洁后再使用ADA参考手动牙刷的效果相当。
在这项小型研究中，欧乐B活力亮白专业型电动牙刷在两次就诊期间实现了具有统计学意义的色斑清除效果。
