title: Antigingivitis efficacy of a stabilized stannous fluoride/sodium hexametaphosphate dentifrice in subjects previously nonresponsive to a triclosan/copolymer dentifrice.
abstract: Antimicrobial agents, such as stannous fluoride and triclosan, have been incorporated into dentifrice formulations and shown to be effective in the prevention and reduction of gingivitis. However, not all subjects respond to treatment. The objective of this study was to assess the antigingivitis efficacy of a 0.454% stannous fluoride/sodium hexametaphosphate dentifrice among subjects who were identified as nonresponsive or minimally responsive to a sodium fluoride/triclosan/copolymer dentifrice. This was a 12-week, examiner-blind, single-center study. Forty-one subjects with no or minimal gingivitis response to 6 months of use of a sodium fluoride/triclosan/copolymer dentifrice were enrolled in this study and 38 of them provided complete data. All subjects were provided with a 0.454% stannous fluoride/sodium hexametaphosphate dentifrice to use over the next 3 months (12 weeks). Subjects were instructed to brush twice daily for 60 seconds using their assigned product. Toothbrushing was supervised for 3 days of each week. Clinical examinations using the Löe-Silness Gingival Index were performed at 6 and 12 weeks posttreatment. The 6-month scores after the use of the sodium fluoride/triclosan/copolymer dentifrice served as the baseline. After 12 weeks of product use, participants had statistically significantly less gingivitis by 54% and statistically significantly less bleeding by 55% on average compared to baseline. No adverse oral soft tissue effects were reported in the study. This study demonstrated that the use of an experimental 0.454% stannous fluoride/sodium hexametaphosphate dentifrice over a 12-week period provides a statistically significant and clinically relevant effect in the control of gingivitis among subjects who previously did not respond to 6 months of use of a sodium fluoride/triclosan/copolymer dentifrice.
