Plaque Reduction of Novel Electric Toothbrush With Sensitive Brush Head

Objectives: This clinical study evaluated the effect of a smart-connected oscillating-rotating electric toothbrush with a sensitive brush head on plaque in a single-use and over a 12-week period.
Methods: This was a 2-treatment, randomized, parallel group, examiner-blind, 12-week clinical trial. 100 subjects with evidence of plaque and gingivitis were randomized to either the Oral-B iO smart-connected electric toothbrush with micro-vibrations and Gentle Care brush head (ETB) or a soft manual toothbrush Control (Oral-B Indicator). Both groups used a standard fluoridated toothpaste to brush their teeth twice daily for the 12-week study. Plaque was assessed at Baseline (pre- and post-brushing), Week 1 and Week 12 (pre-brushing) using the Rustogi Modification of the Navy Plaque Index. Statistical analyses were carried out using an analysis of covariance, treatment comparisons were two-sided tests at the 5% significance level.
Results: In the single-use brushing assessment, ETB group provided statistically significantly (p<0.001) higher plaque reductions (pre-brushing minus post brushing) than the Control, shown as index scores and percentage treatment differences: whole mouth (-0.227;+77.0%), gumline (-0.403; +108.6%) and interproximal (-0.349; +65.7%). Those differences were even more pronounced in lingual sub-regions: overall (+152,9%), gumline (+217.0%) and interproximal (+103.0%), all statistically significant (p<0.001). The ETB toothbrush also showed significantly (p≤0.009) superior plaque reductions (Baseline Pre minus Final Pre at post-Baseline visits) versus the control group over time (after 1 and 12 weeks of product use) with treatment differences at Week 12 for whole mouth (-0.092; +158.7%), gumline (-0.053; +592.8%) and interproximal (-0.241; +298.4%). Differences in lingual sub-regions were also statistically significant (p<0.001) and correspondingly higher versus whole dentition comparisons: overall (+305.0%), gumline (+533.7%) and interproximal (+380.4%).
Conclusions: The novel oscillating-rotating toothbrush with a Gentle Care brush head provided significant improvements in plaque reduction in a single-use and over the 12-week study period as compared to a regular manual toothbrush.
