Adjunctive Benefit of an Essential Oil-containing Mouthrinse in Reducing Plaque and Gingivitis in Patients Who Brush and Floss Regularly: A Six-Month Study1
Benefits of LISTERINE®: Oral Hygiene Routine Study
Objective
Determine the incremental benefit of the adjunctive use of an essential oil-containing antiseptic mouthrinse (LISTERINE® COOL MINT®) to routine brushing and flossing in inhibiting whole-mouth plaque and gingivitis (N=237).
Methodology
Randomized, controlled, observer-blind, parallel-group clinical study of subjects with mild-to-moderate gingivitis.
Results
Whole-mouth mean Plaque Index score at 6 months: BFEO rinse group experienced 56.3% reduction versus BC.
Whole-mouth mean Modified Gingival Index score at 6 months: BFEO rinse group experienced 29.9% reduction versus BC.
B=Brushing.
F=Flossing.
C=Rinsing with control mouthrinse.
EO=Rinsing with an essential oil-containing mouthrinse.
Conclusion
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.
