To assess the plaque removal efficacy of an oscillating/rotating power toothbrush with novel brush head (Oral-B Precision Clean) in comparison to an American Dental Association (ADA) reference manual toothbrush.
This was a replicate-use, single-brushing, two-treatment, examiner-blind, randomized, four-period (visit) study with a crossover design. At each visit, subjects disclosed their plaque with disclosing solution for one minute, and an examiner performed a baseline (pre-brushing) plaque examination (Rustogi, et al. Modification of the Navy Plaque Index). Subjects were then instructed to brush for two minutes (according to manufacturer's instructions) with their assigned power toothbrush or as they normally do with the ADA manual brush under supervision, after which they again disclosed their plaque and were given a post-brushing plaque examination.
Both the power brush and manual brush showed statistically significant plaque reductions from baseline for the whole mouth, along the gingival margin, and on approximal surfaces. The power brush showed statistically significant advantages (p < 0.001) over the manual brush in plaque reduction for whole mouth (28.8%), gingival margin (44.3%), and approximal surfaces (20.7%).
The oscillating/rotating power toothbrush with a novel brush head showed statistically significantly superior plaque reduction (whole mouth, gingival margin, and approximal surfaces) compared to a manual toothbrush.
评估一款带有新型刷头的振荡/旋转电动牙刷（欧乐-B精准清洁牙刷）与美国牙科协会（ADA）参考手动牙刷相比的牙菌斑清除效果。
这是一项采用交叉设计的重复使用、单刷、双治疗、检查者盲法、随机、四阶段（访视）研究。每次访视时，受试者用显影液暴露牙菌斑一分钟，然后检查者进行基线（刷牙前）牙菌斑检查（Rustogi等人对海军牙菌斑指数的改良版）。然后，受试者按照制造商的说明，使用分配的电动牙刷刷牙两分钟，或在监督下像平时使用ADA手动牙刷一样刷牙，之后他们再次暴露牙菌斑并接受刷牙后牙菌斑检查。
电动牙刷和手动牙刷在全口、龈缘和邻面的牙菌斑减少量与基线相比均有统计学意义。电动牙刷在全口（28.8%）、龈缘（44.3%）和邻面（20.7%）的牙菌斑减少方面比手动牙刷具有统计学意义上的显著优势（p < 0.001）。
与手动牙刷相比，带有新型刷头的振荡/旋转电动牙刷在减少牙菌斑方面具有统计学意义上的显著优势（全口、龈缘和邻面）。
