This double‐blind, controlled clinical study compared the effectiveness of 30‐ and 60‐s listerine rinses in both inhibiting the development of, and reducing existing, supragingival plaque and gingivitis, using an experimental gingivitis model. 94 subjects completed this study. For each subject, a modified gingival index, modified Quigley‐Hein plaque index and Eastman interdental bleeding index were recorded at baseline and at 2 weeks. Following the baseline examinations, subjects received half‐mouth prophylaxes, and began 2 × daily supervised rinsing either with listerine for 30 or 60 s or with a control mouthrinse for 30 s as their sole oral hygiene measure. Statistical analysis (ANCOVA) showed that both the 30‐ and 60‐s listerine rinses were significantly ( p <0.01) more effective than the control in inhibiting and reducing plaque, gingivitis and gingival bleeding. Although 60‐s rinses with listerine were significantly more effective ( p <0.01) than 30‐s rinses in controlling plaque, the 2 rinse durations were similarly effective in controlling interdental bleeding and gingivitis. This study confirms the recommendation of 2 × daily rinsing with listerine for 30 s as an effective regimen for gingivitis control.
