BACKGROUND This article highlights a stabilized stannous fluoride (SnF2) dentifrice that, in addition to being efficacious against caries, gingivitis, and dentin hypersensitivity, demonstrates high-performing stain prevention and removal efficacy. METHODS An in vitro stain prevention model evaluated the efficacy of Colgate TotalSF containing 0.454% SnF2 and 1% zinc phosphate compared with Crest Pro-Health Whitening Power (The Procter & Gamble Company) and a nonabrasive SnF2 gel. L*, a*, and b* values were measured to assess whiteness comparing untreated and stained teeth, and with statistical analysis. A stain removal clinical study was conducted as a randomized, double-blind, 2-cell, parallel-group design using Colgate TotalSF and nonwhitening regular fluoride toothpaste. Participants were instructed to brush twice daily for 6 weeks and were examined for Lobene Composite Stain Index scores, with statistical analysis used at a significance of P < .001. RESULTS In an in vitro stain prevention study, Colgate TotalSF performed 26% and 35% better than a competitor paste and nonabrasive SnF2 gel, respectively. In a clinical study, Colgate TotalSF use showed statistically significant extrinsic tooth stain reductions by 17.5% (3 weeks) and 27.8% (6 weeks) relative to regular fluoride toothpaste. No adverse effects were reported. CONCLUSIONS The results indicate that the stabilized Colgate TotalSF performed statistically better than other SnF2 pastes in an in vitro study, and statistically better than a regular fluoride toothpaste in a clinical study. PRACTICAL IMPLICATIONS Colgate TotalSF offers an SnF2-based therapeutic dentifrice with notable performance in stain prevention and removal.
