This study investigated the effect of rinsing with LISTERINE^® on levels of representative subgingival bacteria in subjects with mild-to-moderate periodontitis.¹

After baseline subgingival sampling, 37 qualifying subjects rinsed with LISTERINE^® or a negative control twice daily for 14 days, with a post-treatment sample obtained on day 15. Following a washout period, the procedure was repeated with the alternative rinse. Target organisms were Porphyromonas gingivalis, Fusobacterium nucleatum, Veillonella sp., and total anaerobes.¹

Level of target organisms after twice daily rinsing with LISTERINE^® for 14 days – reduction versus control¹

Randomised, double-masked, 2 x 2 crossover design.

The authors concluded, "This study demonstrated that rinsing with the essential oil-containing mouthrinse can reduce significantly subgingival levels of target bacteria associated with periodontal diseases".¹
