Clinical Trial Summary

This is a clinical investigation to measure the changes in the oral environment resulting from a 3 month exposure to an arginine containing toothpaste. This study is a double blind, randomized controlled, parallel design. Seventy (70) male and female subjects who meet the inclusion/exclusion criteria will be enrolled in the study. Following oral health evaluations, subjects will be assigned to the treatment schedule and receive their assigned study product.
