A randomized 12-week study to compare the gingivitis and plaque reduction benefits of a rotation-oscillation power toothbrush and a sonic power toothbrush.
J Clin Dent. 2009; 20(3):93-8.JC

Abstract

OBJECTIVE

Sonic and rotation-oscillation power toothbrushes are popular and effective, but have been shown to differ in relative benefits. The objective of this 12-week investigation was to compare the efficacy of a rotation-oscillation powered toothbrush and a newly introduced sonic toothbrush in the reduction of gingivitis and dental plaque.

METHODS

This was a randomized, controlled, examiner-blind, two-treatment, parallel-group study to assess gingivitis reduction and plaque reductions after twice-daily brushing with either the rotation-oscillation brush or the sonic toothbrush over 12 weeks. The Modified Gingival Index (MGI) and Gingival Bleeding Index (GBI) were used to determine gingivitis benefits at Week 6 and Week 12, and plaque was scored at these visits before and after supervised brushing using the Rustogi Modified Navy Plaque Index (RMNPI).

RESULTS

In 171 evaluable subjects, gingivitis reduction benefits were significantly greater for the rotation-oscillation brush group than for those using the sonic toothbrush, with relative mean benefits favoring the rotation-oscillation brush of 29.4% for GBI and 8.2% for MGI at 12 weeks (p < or = 0.01). The rotation-oscillation brush produced significantly lower RMNPI plaque by 33.3% compared to the sonic toothbrush (p < 0.001) at Week 12.

CONCLUSION

The rotation-oscillation power toothbrush was significantly more efficacious than the sonic toothbrush in removing plaque, in reducing gingivitis, and lowering the number of bleeding sites after 12 weeks of twice-daily brushing.
