Many adolescents have poor plaque control and sub-optimal toothbrushing behavior. Therefore, we compared the efficacy of an interactive power toothbrush (IPT) to a manual toothbrush (MT) for reducing dental plaque and improving toothbrushing compliance.
In this randomized, parallel single-blind clinical study, adolescents brushed twice daily with either a MT (Oral-B® Indicator soft manual toothbrush) or an IPT (Oral-B® ProfessionalCare 6000 with Bluetooth). Subjects brushed for 2 min, plus an additional 10 s for each 'Focus Care Area'. At screening and Week 2, afternoon pre-brushing plaque was assessed via the Turesky Modification of the Quigley-Hein Plaque Index (TMQHPI), and supervised brushing duration was measured.
Sixty subjects were randomized; 98% completed. At Week 2, the mean reduction in whole mouth plaque relative to baseline was 34% (p < 0.001) for the IPT versus 1.7% (p = 0.231) for the MT. For Focus Care Areas, the IPT yielded a 38.1% mean TMQHPI reduction (p < 0.001) versus 6.2% for the MT (p < 0.001). Mean brushing time versus baseline increased 34 s in the IPT group (p < 0.001) while remaining flat in the MT group (p = 1.0).
Over 2 weeks, adolescents using an IPT experienced superior plaque reduction and increased overall brushing time versus those using a MT.

许多青少年牙菌斑控制不佳,刷牙行为也未达到最佳状态。因此,我们比较了一款交互式电动牙刷(IPT)与一款手动牙刷(MT)在减少牙菌斑和提高刷牙依从性方面的效果。
在这项随机、平行单盲临床研究中,青少年每天使用MT(欧乐B® 指示型软毛手动牙刷)或IPT(带蓝牙功能的欧乐B® 专业护理6000型)刷牙两次。受试者刷牙2分钟,每个“重点护理区域”额外增加10秒。在筛查时和第2周,通过Turesky对Quigley-Hein菌斑指数的改良版(TMQHPI)评估下午刷牙前的菌斑情况,并测量监督下的刷牙时长。
60名受试者被随机分组;98%完成了试验。在第2周时,IPT组全口牙菌斑相对于基线的平均减少率为34%(p < 0.001),而MT组为1.7%(p = 0.231)。对于重点护理区域,IPT组TMQHPI平均降低38.1%(p < 0.001),MT组为6.2%(p < 0.001)。IPT组的平均刷牙时间相对于基线增加了34秒(p < 0.001),而MT组保持不变(p = 1.0)。
在两周时间里,使用IPT的青少年与使用MT的青少年相比,牙菌斑减少效果更佳,且总体刷牙时间增加。
