Dentin Hypersensitivity: An enigma

The objective of this review is to provide a general view of the aetiology, characteristics and treatment of dentinal hypersensitivity, so that professionals can use this information in the therapeutic management of this clinical condition. The presenting symptoms of sensitive teeth are multi-factorial, and from the perspective of restorative dentistry, makes a differential diagnosis of true dentine hypersensitivity a challenge. Dentin hypersensitivity is diagnosed after elimination of other possible causes of the pain. Desensitizing treatment should be delivered systematically, beginning with prevention and at-home treatments. The latter may be supplemented with in-office modalities. The prevalence of dentin hypersensitivity varies widely, depending on the mode of investigation.
