title: Dentinal hypersensitivity: a review.
abstract: Dentinal hypersensitivity is generally reported by the patient after experiencing a sharp pain caused by one of several different stimuli. The pain response varies substantially from one person to another. The condition generally involves the facial surfaces of teeth near the cervical aspect and is very common in premolars and canines. The most widely accepted theory of how the pain occurs is Brannstrom's hydrodynamic theory, fluid movement within the dentinal tubules. The dental professional, using a variety of diagnostic techniques, will discern the condition from other conditions that may cause sensitive teeth. Treatment of the condition can be invasive or non-invasive in nature. The most inexpensive and efficacious first line of treatment for most patients is a dentifrice containing a desensitizing active ingredient such as potassium nitrate and/or stannous fluoride. This review will address the prevalence, diagnosis, and treatment of dentinal hypersensitivity. In addition the home care recommendations will focus on desensitizing dentifrices.
