Explanation:
Detailed explanation-1: -Three major mechanisms of dentinal sensitivity have been proposed in the literature: Direct innervation theory. Odontoblast receptor. Fluid movement/hydrodynamic theory.
Detailed explanation-2: -The dentin tubules are narrow, fluid-filled channels leading to the dental pulp. Dentinal hypersensitivity is believed to result from movement of the fluid within the dentinal tubules, stimulating the nerves and leading to the characteristic pain of dentin hypersensitivity in the presence of stimuli.
