DENTIN HYPERSENSITIVITY

Dentinal hypersensitivity is a common problem affecting over the general population. Dentinal hypersensitivity can be detected after removing all the other factors which can possibly cause the pain. It is characterized by sharp transient pain in response to stimulus and is associated with dentin exposure and the diagnosis is made after excluding another dental defect. The most accepted theory for dentinal hypersensitivity is fluid hydrodynamic theory. Management of dentinal hypersensitivity is mainly aimed at either blocking the fluid flow by occlusion of dentinal tubule or disturb the neural response to pain stimulus which can be successfully managed by a very wide variety of procedures, agents and formulations applied locally, either "in office" or "at home".
