Comparative study of four over-the-counter mouthrinses claiming antiplaque and/or antigingivitis benefits.

The efficacy of over-the-counter mouthrinses claiming to have antiplaque/antigingivitis benefits was compared using the modified Löe-Silness Gingival Index and the Quigley-Hein Plaque Index. The double-blind in vivo study involved 122 subjects. Each subject was randomly assigned to one of five groups. Gingival inflammation and plaque were evaluated at 0, 2, 4 and 6 weeks of product use. Results revealed that plaque scores for some of the products were statistically significant from the control at the 4-week and 6-week visits. Changes in the gingival scores were negligible.
