Solving the problem with stannous fluoride: Extrinsic stain

Abstract

Background: This article highlights a stabilized stannous fluoride (SnF 2 ) 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 Total SF containing 0.454% SnF 2 and 1% zinc phosphate compared with Crest Pro-Health Whitening Power (The Procter & Gamble Company) and a nonabrasive SnF 2 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 Total SF 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
