Efficacy of an Electric Toothbrush/Sensitive Brush Head for Gingivitis Reduction
Objectives: The aim of this research was to evaluate the efficacy of a smart-connected oscillating-rotating electric rechargeable toothbrush with micro-vibrations with a sensitive brush head to a manual toothbrush for reduction of gingivitis and plaque over 12 weeks.
Methods: This was a 12-week, single-center, examiner-blind, 2-treatment, parallel group, randomized controlled trial. 100 subjects with evidence of gingivitis and plaque were enrolled and randomized to either the Oral-B iO oscillating-rotating smart-connected electric rechargeable toothbrush (ERT) with micro-vibrations and Gentle Care brush head or a soft manual toothbrush (MAN) balancing for baseline gingivitis and plaque scores, baseline number of bleeding sites and tobacco use.Subjects brushed with their assigned toothbrush and a standard sodium fluoride dentifrice twice daily for the 12-week study duration.Gingivitis was assessed at Baseline, Week-1 and Week-12 using the Modified Gingival Index and Gingival Bleeding Index.Plaque was assessed at Baseline (pre- and post-brushing), Week-1 (pre-brushing) and Week-12 (pre-brushing) using the Rustogi modification of the Navy Plaque Index (RMNPI). Oral Soft Tissue examinations were also conducted at Baseline, Week-1 and Week-12.
Results: All 100 subjects finished the study. Subjects had a mean age of 49.1 years; 72% were females. At Week-12, 46 (92%) of subjects using the ERT toothbrush were categorized as “Generally Healthy” (<10% bleeding sites) according to the new periodontal classifications compared to 12 (24%) of subjects in the MAN group (p<0.001). Gingival health improvements of ERT versus the MAN control was statistically significant on all endpoints (MGI, GBI, #bleeding sites; p< 0.001). ERT also provided statistically significantly greater plaque reductions in the whole mouth, in the interproximal region and along the gumline compared to the manual brush starting from Day 1 and continuing at 12 Weeks (p≤0.009).
Conclusions: The novel oscillating-rotating electric toothbrush with micro-vibrations with the sensitive brush head provided statistically significantly greater plaque and gingivitis reductions than a manual toothbrush over 12 weeks.
