Webb30 mars 2012 · Dentine hypersensitivity (DH) is an abnormal response of the exposed vital dentine to thermal, chemical, or tactile stimuli. The prevalence of DH has been reported ranging from 4 to 57% in many studies in the literature, depending on the population samples studied [ 1, 2 ]. WebbThe dentine innervation theory is based on the premise that dentine is innervated and that the stimulation of the nerve endings within dentinal tubules causes hypersensitivity. [43] …
WebbDentin’s sensitivity to stimuli does not lead to any prob-lem while it is covered with protective tissues; enamel and cementum. The results of scanning electron micro-scope (SEM) indicate that the number of tubules in sen-sitive dentin is eight times more than the number of tubules in non sensitive dentin. Furthermore, tubules of WebbTheories A variety of theories have been suggested to help explain the mechanism involved in the etiology of dentinal hypersensitivity. 11 The transducer theory, the modulation theory, the “gate” control and vibration theory, and the hydrodynamic theory have all been presented and discussed throughout the years.
