Stain Removal Performance of An Improved Dentifrice

OBJECTIVE: The objective of this randomized, double-blind, parallel-group clinical study was to compare the extrinsic stain removal efficacy of a new dentifrice containing 0.3% Triclosan, 2.0% Copolymer and 0.243% Sodium Fluoride with a new generation silica cleaning system as compared to a commercially available non-tooth whitening placebo dentifrice, as measured by the Modified Lobene Stain Index.

METHODS: Following a baseline examination for extrinsic tooth stain, qualifying adult male and female subjects from the Piscataway, New Jersey area were randomized into two treatment groups balanced for gender, age, and tooth stain scores. Subjects were instructed to brush their teeth twice daily (morning and evening) for one minute with their assigned dentifrice, using a soft bristled toothbrush that was provided. Extrinsic tooth stain examinations were done at baseline, 3 weeks and 6 weeks of product use.

RESULTS: After three weeks and six weeks of dentifrice use, subjects using the dentifrice containing 0.3% Triclosan, 2.0% Copolymer and 0.243% Sodium Fluoride with a new generation silica cleaning system exhibited statistically significantly lower levels of extrinsic tooth stain area and intensity than those subjects who used the commercially available non-tooth whitening placebo dentifrice (32% at 3 weeks and 48% at six weeks difference in tooth stain area and 26% at 3 weeks and 40% at six weeks difference in tooth stain intensity).

CONCLUSION: The results of this clinical study support the conclusion that a new dentifrice containing 0.3% Triclosan, 2.0% Copolymer and 0.243% Sodium Fluoride with a new generation silica cleaning system is efficacious in extrinsic tooth whitening as compared to a commercially available non-tooth whitening placebo dentifrice.
