Rembrandt toothpaste: stain removal following the use of Peridex.
Eighteen subjects participated in a stain removal study following two months of Peridex use. The subjects were randomly assigned to use either Rembrandt dentifrice or Crest dentifrice for two months. Indices for stain area and intensity were taken at baseline, two, four, and eight weeks. After eight weeks' use, the Rembrandt group had a 37.1% lower stain area score on facial and 30% lower stain score on lingual surfaces compared to the Crest dentifrice group. On total surface stain area, the Rembrandt group was significantly lower than the Crest dentifrice group at p less than .05. Over eight weeks, the Rembrandt group had a significant drop in stain area while the Crest group had no significant change. On the stain intensity index, there was a 45.7% reduction on facial surfaces and 38.2% on lingual surfaces compared to the Crest dentifrice group which was significant at p less than .01.
