Efficacy in reducing dentine hypersensitivity of a regimen using a toothpaste containing 8% arginine and calcium carbonate, a mouthwash containing 0.8% arginine, pyrophosphate and PVM/MA copolymer and a toothbrush compared to potassium and negative control regimens: an eight-week randomized clinical trial.

Objective: Evaluate the efficacy of three regimens integrating toothpaste, toothbrush and mouthwash in reducing dentine hypersensitivity.

Methods: Eight-week single-centre, three-cell, double-blind, randomized study was conducted in the Dominican Republic. Subjects entered one of the three regimens: (1) toothpaste containing 8% arginine and 1450 ppm mono-fluorophosphate, in a calcium carbonate base, a soft-bristle toothbrush followed by a mouthwash containing 0.
