The use of adjunctive LISTERINE®

The use of adjunctive LISTERINE® significantly impacts plaque regrowth

Daily brushing and flossing are more effective at controlling plaque when LISTERINE® is added. In this randomised, placebo controlled, unsupervised study, 246 patients were assigned to brushing + control rinse, brushing + flossing + control rinse or brushing + flossing + LISTERINE® for 6 months; patients were evaluated for a number of measures including Plaque Index. When used for 6 months, the adjunctive use of LISTERINE®, produces an incremental whole-mouth plaque reduction of 51.9%, compared with brushing and flossing alone.1

Reduction in interproximal mean plaque index.

In the same study, LISTERINE® decreased interproximal plaque by 47.7% more than brushing and flossing alone when used for 6 months. The authors concluded that this was a significant incremental improvement over the standard regimen of brushing and flossing.1
