To evaluate the efficacy of an oscillating-rotating (O-R) electric rechargeable toothbrush with a novel round brush head comprised of regular and tapered bristles in reducing plaque and gingivitis versus a manual toothbrush.
This was a randomized, examiner-blind, parallel group, five-week study. Participants with mild-to-moderate plaque and gingivitis received an oral examination and were evaluated for baseline plaque (Rustogi Modified Navy Index), gingivitis (Modified Gingival Index) and gingival bleeding (Gingival Bleeding Index). Qualifying participants were randomly assigned to the novel Oral-B sensitive brush head (EB60) on an Oral-B Vitality O-R handle (D12) or an ADA manual toothbrush. Participants brushed twice daily with the assigned brush and a standard fluoride dentifrice for 5 weeks before returning for an oral examination and plaque and gingivitis evaluations.
A total of 150 participants were randomized to treatment and completed the study (mean age = 45.7 years). Both brushes demonstrated a statistically significant reduction in number of bleeding sites versus baseline (P < 0.001). At Week 5, the number of bleeding sites was reduced from baseline by 11.15 (52.2%) for the O-R brush and 5.04 (23.6%) for the manual brush. The treatment difference was statistically significant (P < 0.001). Significant reductions versus baseline (P < 0.001) were also seen for both brushes for MGI, GBI and Rustogi plaque measures (whole mouth, gingival margin and proximal), but the O-R brush produced significantly greater reductions versus the manual brush (P < 0.001).
The O-R handle and round brush head with tapered and regular bristles produced greater plaque and gingivitis reductions than the manual brush.
评估一款配备由常规刷毛和锥形刷毛组成的新型圆形刷头的可充电旋转振荡（O-R）电动牙刷相对于手动牙刷在减少牙菌斑和牙龈炎方面的疗效。
这是一项随机、检查者盲法、平行组、为期五周的研究。患有轻度至中度牙菌斑和牙龈炎的参与者接受了口腔检查，并对基线牙菌斑（Rustogi改良海军指数）、牙龈炎（改良牙龈指数）和牙龈出血（牙龈出血指数）进行了评估。符合条件的参与者被随机分配使用Oral-B活力O-R手柄（D12）上的新型Oral-B敏感刷头（EB60）或ADA手动牙刷。参与者每天使用指定的牙刷和标准含氟牙膏刷牙两次，持续5周，然后返回进行口腔检查以及牙菌斑和牙龈炎评估。
共有150名参与者被随机分配接受治疗并完成了研究（平均年龄 = 45.7岁）。与基线相比，两种牙刷的出血部位数量均有统计学显著减少（P < 0.001）。在第5周时，O-R牙刷的出血部位数量较基线减少了11.15（52.2%），手动牙刷减少了5.04（23.6%）。治疗差异具有统计学显著性（P < 0.001）。两种牙刷在MGI、GBI和Rustogi牙菌斑测量指标（全口、牙龈边缘和邻面）方面与基线相比也有显著减少（P < 0.001），但O-R牙刷相对于手动牙刷产生了显著更大程度的减少（P < 0.001）。
配备锥形和常规刷毛的O-R手柄及圆形刷头在减少牙菌斑和牙龈炎方面比手动牙刷更有效。
