“…evaluated the relative plaque‐reducing single‐use benefits of electric versus manual toothbrushes and stated, ‘A single brushing model provides a useful indication of the plaque removal ability of a toothbrush and facilitates control of confounding variables such as compliance, frequency of toothbrushing and probably even the Hawthorne and novelty effects.’ In that review, a sub‐analysis of the clinical trials using O‐R electric toothbrushes with pre‐ and post‐brushing scores found significantly superior TMQHPI plaque reduction ( P < 0.001) compared to a manual brush. Similarly in their crossover, single‐use clinical trial in a paediatric population, Davidovich et al 25 . reported a significant ( P < 0.001) between‐treatment TMQHPI difference of 0.233–0.298 (depending on examiner) in a paediatric population favouring the O‐R electric brush over the manual toothbrush; by comparison the benefit for the O‐R benefit was even larger in the current trial.…”

Objective The objective was to assess plaque removal potential of a newly designed oscillating‐rotating (O‐R) electric rechargeable toothbrush with micro‐vibrations compared to a manual toothbrush. Methods This was a randomized single‐brushing, two‐treatment, examiner‐blind, replicate‐use, four‐period crossover design study, conducted with three cohorts of nine subjects each, with all subjects using each toothbrush twice. Test toothbrushes included a new O‐R rechargeable electric toothbrush with micro‐vibrations (Oral‐B iO prototype) and a manual American Dental Association (ADA) reference toothbrush. On each of the four study visits, subjects refrained from oral hygiene for 12 hours prior. At each visit, subjects received a pre‐brushing plaque examination, brushed with their assigned toothbrush and a marketed fluoride dentifrice and then received a post‐brushing plaque examination. Plaque was assessed using the expanded Turesky Modified Quigley‐Hein Plaque Index. Treatment comparison analyses were two‐sided and carried out at the 5% significance level. Results All 27 randomized subjects (mean age = 42.0 years) completed the trial. Both brushes produced significant plaque reductions versus baseline (P < 0.001). The O‐R electric brush provided statistically significantly greater plaque reductions in all regions compared to the regular manual toothbrush, with a between‐treatment difference of 0.929 for whole mouth plaque, 0.965 for proximal plaque, 1.029 for lingual plaque and 0.815 for facial plaque (P < 0.001 for all comparisons). Additionally, use of the novel O‐R brush yielded greater brushing evenness/consistency when comparing the facial and lingual mean plaque removal differences relative to manual brushing (P = 0.001). Both brushes were well‐tolerated. Conclusion The novel O‐R toothbrush with micro‐vibrations produced significantly greater plaque reductions compared to the manual toothbrush.

“…Another study in children aged 6 to 11 years demonstrated superior plaque reduction with a Braun Oral‐B children's electric toothbrush relative to a manual brush over a 30‐day home use period and in single‐use supervised brushing at baseline 18 . Previous work from our group in 8 to 11 year olds showed superior plaque removal efficacy with a Braun Oral‐B children's electric toothbrush compared to a manual brush in a randomised, replicate‐use, single‐brushing, crossover clinical trial 15 …”

“…If the younger children had any permanent teeth, they were excluded from the analysis. A sample size calculation based on previous research using a similar study design 15 indicated 20 subjects completing in a 2‐treatment 4‐period crossover study would give a two‐tailed alpha = 0.1 with at least 80% power to detect a difference between treatments of at least 0.144 for mixed dentition and at least 0.141 for primary dentition. TMQHPI across the whole mouth (excluding any permanent teeth for the 3‐6 year old group) was the primary variable.…”

Background Clinical investigations of electric toothbrushes in young children are limited. Aim To assess plaque reduction efficacy of an oscillating‐rotating electric versus manual toothbrush in a paediatric population in primary and mixed dentitions. Design In this randomised, single‐brushing, 2‐treatment, 4‐period, replicate‐use crossover study, subjects were divided into 2 age groups (3‐6 years; 7‐9 years) and assigned to a treatment sequence involving an Oral‐B Kids electric brush and a manual brush control. Plaque was assessed pre‐ and post‐brushing (Turesky Modified Quigley‐Hein Plaque Index). Parents brushed the teeth of their children aged 3‐6 years, whereas children aged 7‐9 years brushed their own teeth under supervision. Plaque removal scores were analysed for brush differences in each age group separately using an analysis of covariance for crossover design. Results Forty‐one children (n = 20, 3‐6 years; n = 21, 7‐9 years) completed the study. For the primary dentition in children 3‐6 years, the electric brush reduced 32.3% more plaque than the manual brush (P = .005). For the mixed dentition in children 7‐9 years, the electric brush reduced 51.9% more plaque than the manual brush (P < .001). Conclusions An electric toothbrush reduced significantly more plaque than a manual toothbrush in 2 paediatric age groups.

Gingival health benefits have been demonstrated across various patient populations, including post‐surgical patients, pediatric patients, orthodontic patients, and adolescents 28‐32 . The O‐R movements disrupt and remove plaque via rapid shearing forces while the round brush head maximizes access in hard‐to‐reach areas.…”

Purpose A novel oscillating‐rotating electric toothbrush (Oral‐B iO) has been developed with a linear magnetic drive, resulting in oscillation‐rotations with micro‐vibrations. The mechanism directs motor energy directly to the bristle tips. The brush also has a redesigned round brush head and smart pressure sensor to enhance plaque removal and encourage proper brushing technique. Methods The plaque removal and gingival health effects of this new electric toothbrush technology were evaluated in three randomized controlled studies summarized in this supplement, including an 8‐week trial versus a manual toothbrush, an 8‐week trial versus a premium sonic toothbrush, and a single‐brushing, repetitive‐use study versus a manual toothbrush. Results Outcomes from these studies demonstrate statistically significantly greater plaque removal and gingival health improvements for the Oral‐B iO toothbrush technology versus manual and sonic toothbrush controls. Plaque removal advantages demonstrated in the replicate‐use single‐brushing trial resulted in significant gingival health benefits as evidenced in the longer‐term trials. In addition, gingivitis case status assessments based on the American Academy of Periodontology (AAP) and European Federation of Periodontology (EFP) guidelines show that over 80% of subjects using the Oral‐B iO transitioned from ‘gingivitis’ (≥10% bleeding sites) at baseline to ‘generally healthy’ (<10% bleeding sites) at week 8 in both longer‐term clinical trials, versus 24% in the manual toothbrush group and 53% in the sonic toothbrush group. Conclusions This uniquely designed oscillating‐rotating electric toothbrush with a linear magnetic drive delivers significantly greater plaque removal and gingival health benefits with additional features to improve brushing experience and clinical outcomes.
