Systematic Review and Meta Analysis of the Relative Effect on Plaque Index among Pediatric Patients Using Powered (Electric) versus Manual Toothbrushes

Abstract

Although many randomized controlled trials (RCT) have evaluated the efficacy of powered or electric toothbrushes compared with manual or traditional toothbrushes to remove biofilm and plaque, only one systematic review has been published for pediatric patients. The primary objective of this study was to perform a systematic review and meta analysis for this population. Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol, N = 321 studies were initially identified. Three independent, blinded abstract reviews were completed resulting in a total of n = 38/322 or 11.8% for the final analysis (n = 27 non-orthodontic, n = 11 orthodontic studies). Meta analysis of these outcome data have revealed a strong reduction in plaque index scores among pediatric patients using electric toothbrushes of approximately 17.2% for non-orthodontic patients and 13.9% for orthodontic patients. These results provide strong clinical evidence for recommending electric toothbrushing to pediatric patients, as well as those patients undergoing orthodontic therapy and treatment.
