Dentine Tubule Occlusion Assessment in a Modified in Situ Model

This will be a single centre, single blind, randomized, three treatment, three period crossover design, modified, in situ, study in healthy participants. In this in situ model the tubule occlusion properties of dentifrices will be evaluated by comparing an experimental dentifrice formulation to a regular fluoride dentifrice and a negative control (mineral water) over a ten day period.
