Brief Summary
This trial aims to evaluate the efficacy of three experimental dentifrices to remove denture biofilm. Complete denture wearers will be instructed to brush their dentures with a specific toothbrush and four compositions: (1) A proprietary denture-specific paste (active comparator); (2) 0.2% chloramine T; (3) 1.0% chloramine T; (4) 0.01% fluorosurfactant. Each treatment will be used for periods of 7 days, and participants will be randomized to use them according to one of four sequences.
