Witt, Jon J; Gibb, Roger; Hamilton, Amy; Lang, Niklaus Peter; Albert-Kiszely, Andrea; Pjetursson, Bjarni E.; Salvi, Giovanni; Persson, Gösta Rutger (2006). Comparative efficacy of two mouthrinses in a 6-month study. In: American Association for Dental Research (AADR) Meeting & Exhibition. Orlando, FL, USA. March 8-11, 2006.

Objective: The objective of this study was to compare the effects of a commercial CPC (cetylpyridinium chloride) mouthrinse containing 0.07% CPC (Crest® ProHealth Rinse) versus those provided by a commercial essential flavor oil mouthrinse (Listerine® Antiseptic) on dental plaque accumulation and prevention of gingivitis in an unsupervised 6 month clinical study. Methods: This was a double blind, 6-month, parallel group, positive controlled study involving 128 subjects who were balanced and randomly assigned to either positive control (essential oil) or experimental (CPC) mouthrinse treatment groups. The CPC mouthrinse passed proposed performance assays by the FDA for an OTC CPC mouthrinse. At baseline, subjects received a dental prophylaxis and began unsupervised rinsing twice daily with 20 ml. of their assigned mouthrinse for 30 seconds after brushing their teeth for 1 min. Subjects were assessed for gingivitis and gingival bleeding by the Gingival Index (GI) of Loe and Silness and plaque by the Silness and Loe Plaque Index (PI) at baseline and after 3 and 6 months of product use. Oral soft tissue health was also assessed. Microbiological samples were also taken for community profiling by the DNA-DNA checkerboard method. Results: Results show that after 3 and 6 months use there was no significant difference (p = 0.05) between the CPC and essential oil mouthrinse treatment groups for overall gingivitis status, gingival bleeding, and plaque. At 6 months the covariant (baseline) –adjusted mean GI and bleeding sites numbers for the CPC and essential oil mouthrinses were 0.52 and 0.53 and 5.5 and 6.3, respectively. Both mouth rinses were well tolerated by the subjects. Microbiological community profiles were similar for the 2 treatment group. Conclusion: This study shows that the 0.07% CPC mouthrinse can provide similar plaque and gingivitis benefits to those provided by an essential oil mouthrinse over a 6 month period.
