Maintaining periodontal health requires the effective removal of dental plaque, particularly from the gingival margins and interdental surfaces where plaque control is notably challenging. Although electric toothbrushes are known for their superior plaque removal capabilities, a comprehensive review focusing on their efficacy in cleaning interdental surfaces has been lacking.
Research Methodology and Data Extraction
The study employed a meticulous search strategy across three databases: MEDLINE, DOSSS via EBSCOhost, and Embase, up to October 2023. The inclusion criteria were strictly applied, and a risk of bias assessment was performed. Out of 77 identified studies, 14 were deemed eligible for analysis. The findings were synthesized narratively, and a meta-analysis was conducted where applicable.
Key Findings and Statistical Outcomes
The analysis revealed a mean difference in interproximal plaque reduction favoring oscillating-rotating toothbrushes. At the 8-week mark, the reduction, as measured by the Rustogi Modified Naval Plaque Index (RMNPI), was 0.09 (p < 0.00001). At 6 and 12 weeks, the mean differences were 0.05 (p = 0.0008) and 0.04 (p = 0.0001), respectively, still in favor of the oscillating-rotating technology.
The data underscored the increased efficacy of oscillating-rotating toothbrushes in removing interproximal plaque compared to oscillating toothbrushes, particularly in shorter-duration studies (8 weeks).
Practical Implications for Oral Healthcare
– For effective interproximal plaque removal, oscillating-rotating toothbrushes are recommended over oscillating toothbrushes.
– Significant improvement in plaque control can be observed as early as 8 weeks with oscillating-rotating toothbrushes.
– Dental professionals should consider advising patients on the benefits of oscillating-rotating toothbrushes for enhanced periodontal health.
These findings are valuable for dental practitioners aiming to provide evidence-based recommendations to their patients and highlight the importance of selecting the appropriate toothbrush technology for optimal oral hygiene.
