Clinical study to assess the stain removal efficacy of two tartar control dentifrices and a low abrasive dentifrice.

Abstract
Significant differences in stain removal have been demonstrated in a laboratory study comparing two tartar control dentifrices: Platinum, containing 1.3% soluble pyrophosphate and 1.5% of a copolymer, and Crest Tartar Control, containing 5% soluble pyrophosphate. The purpose of this clinical study was to evaluate the same tartar control dentifrices, and a low abrasive dentifrice for their ability to reduce Peridex-induced stain. Eighty-five subjects were given Peridex (0.12% chlorhexidine digluconate) and a low abrasive dentifrice for 4 weeks. The 76 subjects with sufficient stain were stratified using the Lobene index on buccal and lingual surfaces of anterior teeth, and randomly assigned one of the three dentifrices for 8 weeks. At the end of the study, total stain evaluations were significantly lower in the Platinum dentifrice group (mean 0.84) compared to both Crest Tartar Control dentifrice (1.08) and the low abrasive dentifrice (1.09) at p<0.05 by ANOVA. In this 8-week clinical study, Platinum dentifrice was significantly more effective than Crest Tartar Control dentifrice or a low abrasive dentifrice in reducing Peridex-induced stain, and this finding correlates well with laboratory data on removal of tea and coffee stain.
