Landmark, peer-reviewed analysis adds clinical relevance for your everyday practice

  1. Results reported by sites healthy and plaque-free—as opposed to whole-mouth plaque/gingivitis reduction data—allow you to easily set targets for your practice
  2. This analysis reviewed data on the additive benefits of LISTERINE® from randomized, observer-blinded, placebo-controlled studies, including both published and unpublished data
  3. Evidence was drawn from a larger-than-usual population of N>5000 subjects; single studies have an average of 163 subjects

The most robust collection of clinical data of its kind

3.1.1.-image-1.infographic.png

29 Studies of 6 Months’ Duration Over 5000 Patients 3 Countries: United States, Canada & Brazil  4 Decades of Data 500,000+ Sites
  • 1 landmark analysis: enabled broader, more clinically relevant conclusions

Analysis compared the results of 2 treatment groups

  • Control group

    • Mechanical methods (MM) alone
    • 2562 patients
  • Experimental group

    • MM + LISTERINE®
    • 2544 patients

Sitewise analysis evaluated efficacy at multiple sites per tooth across the entire mouth

  • Plaque index (PI): 6 sites per tooth

    • Plaque-free sites were defined as those with small pieces of plaque (1) or no plaque (0), based on the PI score
  • Modified gingival index (MGI): 4 sites per tooth

    • Healthy sites were defined as those with mild (1) to no (0) inflammation, based on the MGI scores

LISTERINE® users were more likely to have a cleaner, healthier mouth vs. MM alone

3.1.1-image-2.png

LISTERINE® users had nearly 5x more plaque-free sites at 6 months vs. MM alone and over 2x more healthy gingival sites at 6 months vs. MM alone

LISTERINE® users had more plaque-free sites and more healthy sites — even in the hardest-to-reach areas of the mouth
