Dentinal hypersensitivity is a painful response to a non-noxious stimulus applied to exposed dentine in the oral environment. Dentine exposure results from a combination of two or more aetiological factors that lead to loss of enamel and/or loss of cementum. The hydrodynamic theory is the most accepted theory that explains the excitement of pulpal nerve fibres by a stimulus applied to the exposed dentine. Dentinal hypersensitivity had been reported to affect middle age people most often with no gender differences and has been shown to be influenced by tooth location.
牙本质过敏症是指在口腔环境中，对施加于暴露牙本质的非伤害性刺激产生的疼痛反应。牙本质暴露是由两种或更多种病因导致釉质丧失和/或牙骨质丧失共同作用的结果。流体动力学说为最被认可的理论，该理论解释了施加于暴露牙本质的刺激如何激发牙髓神经纤维。据报道，牙本质过敏症最常影响中年人，无性别差异，且已证明受牙齿位置的影响。
