Dentin hypersensitivity (DH) is a relatively
common problem experienced in clinical dental
practice. This condition has been defined as a short,
sharp pain arising from exposed dentin in response
to stimuli typically thermal, evaporative, tactile,
osmotic or chemical and which cannot be described
to any other form of dental defect or pathology. DH
may ocur as a result of exposed dentinal tubules
through either loss of enamel or gingival recession.
Management strategies, which take into account
aetiological factors and patient’s oral hygeine
behaviour, should be considered before the home or
in office treatment protocols. Treatment plan should
include reduce fluid flow in the tubules by means of
occlude exposed tubules and block the nerve
response in the pulp with many desensitizing
chemical agents or phyisical agents which also
include lasers. The purpose of this review is to
summarize the definition, epidemiology,
mechanism, aetiology, diagnosis and treatment
protocols of dentin hypersensitivity.
