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 ]. WebbScientific methodology has described 3-theories of dentine sensitivity: (1) In 1770 Hunter suggested tooth sensitivity was due to pulpal nerves [4].
