Systematic review and meta-analysis of randomized controlled studies comparing oscillating-rotating and other powered
Background:
The aim of this study was to systematically review and analyze the difference in efficacy of oscillating-rotating toothbrushes compared with other powered toothbrushes.
Methods:
The authors performed a systematic search of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The authors used the population, intervention, comparison, and outcome format to develop a search strategy to answer the study question. The authors searched PubMed-MEDLINE databases. Inclusion criteria were randomized controlled clinical trials comparing oscillating-rotating (OR) toothbrushes with other powered toothbrushes published from January 1, 2009 through March 1, 2019.
Results:
The authors' search resulted in 454 articles; 21 articles were downloaded for review, 15 articles were included in the report, and 12 could be used for meta-analysis. All of the studies were randomized controlled clinical trials that assessed plaque removal and gingival inflammation indexes. Results of the meta-analysis of the randomized controlled clinical trials showed that OR toothbrushes had superior, statistically significant outcomes for whole-mouth plaque reduction, assessed using the Rustogi Modified Navy Plaque Index (P < .01), and gingivitis, assessed by using number of bleeding sites (P < .001), but not for the modified gingival index (P > .05) or gingival bleeding index (P > .05).
Practical Implications:
There is some evidence to suggest that OR powered toothbrushes might remove more plaque and reduce the number of bleedings sites better than other powered toothbrushes, specifically, sonic action toothbrushes.
