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.

Considerations for the development of over-the-counter dentifrices for the treatment and relief of dentin sensitivity.

There have been many recent articles and reviews covering the effectiveness of dentifrices for the treatment and relief of dentin sensitivity. To date, there are no articles which fully examine all the compromises that a dentifrice formulator and manufacturer have to make when developing an effective dentifrice technology in the context of theoretical approaches and proposed modes of action. This article provides a first review and discussion of the currently available technologies, nerve depolarization and occluding agents.
