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...
