Evaluation of the Efficacy of Manual Toothbrush Versus Power Toothbrush in Reduction of Gingivitis: A Comparative Clinical Study

Background: In our study, we compare the power toothbrush with the manual toothbrush and the results showed were contradictory. Where few studies have reported that power toothbrushes are superior, other studies showed that both are equally efficacious in removing dental plaque. Aims: The present study was conducted to evaluate and compare the efficacy of manual toothbrush with an electric toothbrush in reducing dental plaque and gingivitis. Materials and Methods: The study included a total of 56 subjects which were randomly divided into two groups of 28 subjects each. At week 1, disclosing agent (two-tone solution) was used to detect plaque, and Loe and Silness Gingival Index were used to assess gingival scores. Oral hygiene instructions and brushing were also reinforced. A similar protocol was repeated at one, two, and six weeks. The collected data were subjected to statistical evaluation. Results: At two weeks, the plaque score for manual and power toothbrushes were 60.253 +/- 20.672 and 44.031 +/- 16.484, respectively, and this difference was statistically significant with P = 0.0020. At six weeks, plaque scores for manual and power toothbrushes were 43.784 +/- 22.647 and 20.489 +/- 10.336, respectively, and were statistically significant (P < 0.0001). Conclusion: The present study concludes that powered toothbrush has added advantages of improved oral hygiene compared to manual toothbrush concerning plaque reduction. This can be attributed to predefined power and force which can effectively remove plaque, calculus, and improved gingival health.
