Studies have shown that powered toothbrushes are more effective at removing plaque and improving gingival health when compared to manual toothbrushes.
A meta analysis from the International Dentistry Journal (February, 2024) showed participants using an oscillating-rotating brush had an average of 52% fewer bleeding sites when compared with a manual toothbrush and 29% fewer bleeding sites when compared with a sonic brush. When comparing an iO oscillating-rotating brush to a traditional oscillating-rotating brush, there was a 27% reduction in bleeding sites.
When assessing plaque reduction, an oscillating-rotating brush had superior reduction in plaque by 19% when compared to a manual toothbrush and 5% when compared to a sonic brush.
By 12 weeks, there were a higher percentage of oscillating-rotating brush users (76.3%) than manual brush users (29.8%) or sonic brush users (59.2%) transitioned from baseline gingivitis to a state of gingival health. The average time to transition to a state of health was 8 weeks for oscillating-rotating brush users and 12 weeks for sonic brush users.
Oscillating-rotating toothbrushes offer superior results for transition to health, gingivitis, and plaque reduction when compared to manual and sonic brushes.
