Evidence for the efficacy of an 8% strontium acetate dentifrice for instant and lasting relief of dentin hypersensitivity.

An 8% strontium acetate, 1040 ppm sodium fluoride-based dentifrice has been demonstrated in in vitro and in situ studies to provide deep and acid-resistant tubule occlusion. Clinical efficacy studies have shown instant and lasting dentin hypersensitivity relief from this dentifrice, which has recently been launched by GlaxoSmithKline Consumer Healthcare as Sensodyne Rapid Relief.
