Tooth hypersensitivity is characterized by a transient short and sharp pain originating from exposed dentin in response to thermal, dehydrating, tactile, osmotic, and chemical stimuli. Tooth sensitivity after cementation of complete coverage crowns, is a rather common event since much of the protecting enamel is removed during preparation and a large area of dentin is exposed. Dentin contains up to two million tubules per cm2, which corresponds approximately to the surface area of most crown preparations. It is well known that such dentin wounds respond to mechanical, osmotic, or thermal stimulation with pain. This phenomenon is commonly example by the hydrodynamic theory of Brannstrom.
