Erbe et al. [42]RCT, replicate single-use, two-treatment, four-period, crossover, examiner-blind study designOscillating-rotating powered toothbrush with orthodontic brush head (Oral-B Triumph, D27/OD17, Procter & Gamble, Cincinnati, Ohio) and sonic toothbrush (Sonicare FlexCare with ProResults brush head, HX6011, Philips Oral Healthcare Inc, Bothell,)N = 44; 17; females 27 males; age: 12 and 25 yearsOscillating-rotating powered toothbrush with orthodontic brush head and sonic toothbrush2 minutes for each brushing, alternating the brushes morning and evening.Plaque was measured, using DPIA The data were analysed using SAS software (SAS Institute Inc., Cary, NC, USA1 weekBaseline plaque levels for both brush treatments were high, covering more than 50% of the tooth area. Effective plaque removal was observed with both toothbrushes (); however, the reduction in plaque with the oscillating-rotating toothbrush was statistically significantly greater () compared with the sonic toothbrush.
Mascarenhas et al. [43]Battery-powered toothbrush (Oral-B Kids) N = 30; all males; age: 9 to 11 yearsManual toothbrush (not otherwise specified)Not reportedPlaque buildup was assessed using the Soparkar modification of the Quigley and Hein Plaque Index.Two weeksAt baseline, there was no difference in plaque removal between battery-powered tooth brushing and manual tooth brushing, either in difference between pre- and post-tooth brushing plaque measures () or in percentage change (). After two weeks of use, there was a statistically significant difference in plaque removal between battery-powered tooth brushing and manual tooth brushing, both in the difference between pre- and post-tooth brushing plaque measures () and in percentage change (). Mean plaque removal by manual tooth brushing was 0.97 ± 0.45, and mean plaque removal by battery-powered toothbrush was 1.23 +± 0.56. Mean percentage change in plaque removal by manual tooth brushing was 33.5 ± 16.05, and mean plaque removal by battery-powered tooth brushing was 43.0 ± 18.82, which represented a 9.5% improvement for battery-powered tooth brushing compared to manual tooth brushing.

Kallar et al. [44]Comparative clinical studyPowered toothbrush (not otherwise specified); N=200; age: 6 to 13 yearsManual toothbrush (not otherwise specified)Not reportedPlaque was recorded according to the Turesky-Gilmore-Glickman modification of Quigley and Hein Index and oral hygiene performance index3, 6, 9, and 12 weeksPowered brushes showed significant plaque reduction as compared to the manual brushes. Supervised group of both brushes showed a greater plaque reduction.
Ghassemi et al. [45]Randomized crossover clinical trialSpinbrush GLOBRUSH, (Arm&Hammer Co, Inc. Princeton, NJ, USA); N = 105; 8-12 years (52 subjects); 13-17 years (53 subjects)Oral-B Indicator 30 compact soft toothbrush (Procter & Gamble Co., Cincinnati, OH, USA)Two minutesMNPI SCORES to evaluate the difference between the subjects’ pre- and post-brushing mean ANCOVAOne weekBetween-group analyses showed that the powered brush produced a statistically significantly greater plaque reduction than the manual brush, both whole mouth (12.8%, ) and at all subset sites, including difficult-to-reach areas such as the posterior lingual gingival region (74.9% greater plaque reduction, ).
Davidovich et al. [46]Randomized clinical studyOral-B Pro-Health For Me Vitality power toothbrush (D12 kids’ handle and EB17 soft brush head; Procter & Gamble, Cincinnati, OH, USA); N=41; age 8-11 yearsOral-B Pro-Expert Cross Action 8+ (OK 011) soft manual toothbrush (Procter & Gamble, Cincinnati, OH, USA)Two minutesTo quantify pre-brushing existing plaque, two clinical examiners conducted a whole-mouth Turesky-modified Quigley and Hein
Plaque Index (TMQHPI) examination.
One weekBoth the powered toothbrush and manual toothbrush provided statistically significant mean plaque reductions as compared to baseline in all analyses (p < 0.001). For both examiners, plaque removal was significantly (p < 0.001) greater for the power toothbrush in permanent and mixed dentitions. The inter-examiner correlations for the permanent dentition were strong (ICC = 0.68-0.88) for pre-brushing plaque across all periods.
