Purpose To compare a novel oscillating‐rotating (O‐R) electric rechargeable toothbrush with micro‐vibrations to a marketed premium sonic toothbrush for reduction of gingivitis and plaque in an 8‐week randomized controlled trial. Methods Adult subjects with evidence of gingivitis and plaque were randomized to use either the novel O‐R brush (Oral‐B iO) or the sonic brush with sodium fluoride dentifrice twice daily. Assessments at baseline and week 8 included the Rustogi Modification of the Navy Plaque Index (RMNPI), Modified Gingival Index (MGI), and Gingival Bleeding Index (GBI). Gingivitis status (‘healthy’/’not healthy’) was classified per the American Academy of Periodontology/European Federation of Periodontology criteria. Results Ninety subjects were randomized to treatment and completed the study. Subjects had a mean age of 49.2 years; 68 were females. At baseline, the mean number (standard deviation [SD]) of bleeding sites for all subjects was 32.8 (16.43). At week 8, the O‐R brush group had a higher percentage of ‘healthy’ gingiva subjects than the sonic brush group (84% vs. 53% P = 0.003). In the between‐group comparisons at week 8, the O‐R brush group showed statistically significantly greater reductions (P < 0.001) compared to the sonic group for MGI, GBI, and number of bleeding sites. The O‐R brush group also had statistically significantly greater plaque removal (P ≤ 0.011) than the sonic brush group for whole mouth plaque as well as plaque in the proximal regions and along the gingival margin. Conclusions The novel O‐R electric toothbrush with micro‐vibrations provided greater plaque and gingivitis reductions than the marketed premium sonic toothbrush over 8 weeks.

“…During the study visit, subjects gave informed consent, followed by a review of their medical history, demographic information, and study inclusion/exclusion criteria. Subjects received a pre‐brushing oral soft tissue assessment and MGI and GBI evaluations by an experienced examiner 12,16,21,22 . After the gingival assessments were completed, plaque was disclosed using Chrom‐O‐Red erythrosine FD&C red 3 disclosing solution (Germiphene Corp., Bradford, Ontario, Canada) according to the manufacturer’s instructions.…”

Purpose To compare a novel oscillating‐rotating (O‐R) electric rechargeable toothbrush with micro‐vibrations (Oral‐B iO) to a manual brush for gingivitis and plaque reduction. Methods Adult subjects with gingivitis and plaque were randomized to use either the O‐R or the manual toothbrush with standard fluoride dentifrice twice daily. Efficacy was assessed at baseline, week 1, and week 8 using the Rustogi Modification of the Navy Plaque Index (RMNPI), Modified Gingival Index (MGI), and Gingival Bleeding Index (GBI). Gingivitis status (‘healthy’/‘not healthy’) was also assessed, per the American Academy of Periodontology/European Federation of Periodontology criteria. Results One hundred and ten subjects were enrolled and completed the randomized controlled trial. The baseline mean number (SD) of bleeding sites for all subjects was 32.11 (16.703). At week 8, 82% of subjects using the O‐R toothbrush were categorized as ‘healthy’ (<10% bleeding sites), versus 24% of subjects using the manual brush (P < 0.001). Subjects using the O‐R toothbrush showed statistically significantly greater reductions (P < 0.001) in the number of bleeding sites, GBI scores and MGI scores versus those using a manual toothbrush as early as 1 week and throughout the 8‐week study. The O‐R toothbrush also provided statistically significantly greater reductions (P < 0.001) in all plaque measures, including sub‐regions, versus the manual toothbrush after a single brushing and at weeks 1 and 8. Conclusions The novel O‐R electric toothbrush with micro‐vibrations provided statistically significantly greater plaque and gingivitis reductions versus a manual toothbrush, with performance benefits demonstrated after a single brushing and continuing throughout the 8‐week study.

“…Since its introduction, Oral‐B has continuously innovated the O‐R rechargeable electric toothbrush design to further improve cleaning, compliance, and the brushing experience. Advancements have included increased oscillations, more ergonomic handle designs, improved brush head design and filament technology, timers, pressure sensors, brushing mode selections, and customizable interactive features via ‘Smart’ technology for real‐time feedback and coaching linking a mobile app and the brush to monitor brushing habits 12,14,33‐39 .…”

Introducing the Oral-B iO electric toothbrush: next generation oscillating-rotating technology

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.
