Dentinal Hypersensitivity Reduction

Completed · Phase 3

Conditions studied: Dentinal Hypersensitivity

In brief

The objective of this clinical study is to assess the efficacy of a dentifrice containing stannous fluoride (Colgate-Palmolive Company, New York, NY, USA) as compared to a commercially-available potassium-based toothpaste (Sensodyne Extra Whitening Toothpaste, GlaxoSmithKline Co., UK) and a commercially available non-desensitizing toothpaste (Colgate Cavity Protection Toothpaste, Colgate-Palmolive Company, New York, NY, USA) in the reduction of dentinal hypersensitivity over a seven (7) day period.
