Plaque index scores reduced over six months by 51.9 per cent
6th Apr 2010
A recent study reveals that for patients with gingivitis who brush and floss routinely, the adjunctive use of a mouthrinse containing essential oils provides a clinically significant and meaningful benefit in reducing plaque that can lead to gingivitis[1].
These are the results of a randomised, controlled, observer blind, parallel group six-month trial conducted by Sharma et al.
The researchers concluded that mechanical methods of dental plaque removal have for many decades been based on the recommended twice daily toothbrushing and daily flossing, or other means of interdental cleaning[2].
For many patients, this mechanical routine does not appear to be entirely sufficient as supported by increasing incidence and prevalence data[3].
The results of the Sharma six month study provide substantial evidence that the adjunctive use of Listerine (Coolmint Antiseptic mouthrinse in this trial) provides a clinically significant and meaningful benefit in reducing plaque in patients with gingival inflammation.
• 56.3% reduction in plaque index scores of regular brush and floss users who additionally used Listerine
• 52.4% reduction in interproximal plaque by adding the essential oil containing mouthrinse to a brushing and flossing routine. By comparison, the addition of flossing only to the brushing routine reduced interproximal plaque by only 8.9%
This long-term study demonstrates that the adjunctive use of an essential oil containing mouthrinse twice daily provides a meaningful and clinically significant incremental benefit to a recommended regimen of brushing twice daily and flossing once daily[1].
Dental professionals should consider recommending a brush, floss and rinse regimen to their patients when brushing and flossing are not enough to maintain gingival health[1].
