Benefits of LISTERINE®: Oral Hygiene Routine Study
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).
Randomized, controlled, observer-blind, parallel-group clinical study of subjects with mild-to-moderate gingivitis.
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.
C=Rinsing with control mouthrinse.
EO=Rinsing with an essential oil-containing mouthrinse.
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.
