Purpose:

This study is to evaluate the effect of fluoride dentifrices on enamel with artificial caries lesions in an in situ model


Study summary:

In situ models represent an acceptable approach for testing the anti-caries potential of fluoride products. This study is to evaluate the effect of fluoride dentifrice containing 1450 parts per million fluoride (ppm F) on enamel with artificial caries lesions in an in situ model. The study toothpaste containing sodium fluoride (NaF) and 0.4% carbopol will be compared to 4 other dentifrices. Comparator toothpastes include NaF toothpaste (1400 ppm F), NaF toothpaste (675 ppm F), sodium monofluorophosphate (NaMFP) and NaF toothpaste (1450 ppm F) and placebo toothpaste (0 ppm F).
