Clinical Study to Evaluate Remineralization Using an in Situ Model.

This is a phase III clinical trial that aims to evaluate the enamel remineralization efficacy of three dentifrices on artificial caries lesions using an in situ model. The study involves 30 healthy volunteers, aged 18 to 70, who will participate in a randomized, triple-blind, three-period crossover design. Researchers will compare a 750 ppm MFP dentifrice against a 1450 ppm MFP positive control and a fluoride-free negative control to measure variations in mineral gain. Participants will wear a removable intraoral appliance containing human enamel blocks for three 14-day experimental phases. A 7-day washout period using will be implemented before and between each treatment phase.
