    Abstract:
    PURPOSE: To investigate the stain preventing ability of a new chlorhexidine mouthwash while maintaining efficacy using a randomized clinical trial design. METHODS: 98 subjects were enrolled and completed a 4-week clinical study that evaluated the effectiveness of the new mouthwash on plaque, gingivitis, and staining as compared to a commercially available chlorhexidine mouthwash. A subset of 62 subjects was evaluated for the effectiveness of the mouthwashes against plaque bacteria. RESULTS: After 4 weeks of use, the new chlorhexidine mouthwash reduced staining by 42.6% (P< 0.05) as compared to the commercially available mouthwash. The two mouthwashes were equivalent with regards to their effect on gingivitis, plaque, and plaque bacteria. CLINICAL SIGNIFICANCE: A new mouthwash, containing 0.12% chlorhexidine gluconate, has been developed that delivers stain reduction while maintaining equivalent efficacy to a commercially available chlorhexidine mouthwash with regards to gingivitis, plaque, and plaque bacteria. These findings should be considered by dental practitioners when making recommendations to patients whose teeth stain easily and need an anti-gingivitis and anti-plaque mouthwash.
