Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a single-center, four-treatment, four-period crossover study. Over the course of the study, up to thirty qualified subjects will use four (4) study treatment products, one time each according to the randomization. Subjects will brush with 1.25g of the assigned study product at each visit. Subjects will provide saliva samples at baseline and at 2, 6, 12, and 30 minutes post-treatment. The F- concentrations in each saliva sample will be determined by ion chromatography
