Listerine Mouthwash is 4.6x More Effective than Floss
for Sustained Plaque Reduction Above the Gumline*
*Flossing by a hygienist
*Sustained plaque reduction above the gumline with continual twice-daily use. Plaque is graded 8 to 18 hours after product use.
A 12-week study reveals exciting data on the benefits of Listerine Antiseptic
Clinical 1: Efficacy of Supervised Mouth Rinsing and Flossing on Plaque and Gingivitis1
To evaluate the efficacy of twice-daily rinsing with Listerine® Antiseptic and brushing vs. flossing and brushing under once-daily supervision for the prevention and reduction of plaque and gingivitis.
- Single center, randomized, supervised, examiner blind, controlled clinical trial conducted at ADA-Qualified site.
- Following a complete prophylaxis, subjects were examined for oral soft tissue status, plaque, gingivitis, and gingival bleeding at Baseline, 4 weeks, and 12 weeks.
- If assigned to a flossing group, subjects were given flossing instructions and demonstrated competency.
- Product use was supervised once daily in person on weekdays with second daily and weekend product use unsupervised.
- 156 subjects (18 years of age and older) with mild-to-severe gingivitis and no severe periodontitis, with no entry criteria on Modified Gingival Index (MGI)/plaque, but must have minimum of 10 gingival bleeding sites.
- The efficacy outcomes included interproximal and whole-mouth mean modified Turesky Plaque Index (TPI), mean MGI, gingival bleeding, bleeding on probing depth, and probing depth.
