Dentinal hypersensitivity is generally reported by the patient after experiencing a sharp pain caused by one of several different stimuli. The pain response varies substantially from one person to another. The condition generally involves the facial surfaces of teeth near the cervical aspect and is very common in premolars and canines. The most widely accepted theory of how the pain occurs is Brannstrom's hydrodynamic theory, fluid movement within the dentinal tubules. The dental professional, using a variety of diagnostic techniques, will discern the condition from other conditions that may cause sensitive teeth. Treatment of the condition can be invasive or non-invasive in nature. The most inexpensive and efficacious first line of treatment for most patients is a dentifrice containing a desensitizing active ingredient such as potassium nitrate and/or stannous fluoride. This review will address the prevalence, diagnosis, and treatment of dentinal hypersensitivity. In addition the home care recommendations will focus on desensitizing dentifrices.
牙本质过敏通常是患者在经历由几种不同刺激之一引起的剧痛后报告的。疼痛反应因人而异。这种情况通常涉及牙齿颈部附近的面部表面，在前磨牙和尖牙中非常常见。关于疼痛如何发生，最被广泛接受的理论是布伦斯特龙的流体动力理论，即牙本质小管内的液体流动。牙科专业人员使用各种诊断技术，将这种情况与可能导致牙齿敏感的其他情况区分开来。这种情况的治疗本质上可以是侵入性的或非侵入性的。对大多数患者来说，最廉价且有效的一线治疗方法是含有脱敏活性成分（如硝酸钾和/或氟化亚锡）的牙膏。本综述将探讨牙本质过敏的患病率、诊断和治疗。此外，家庭护理建议将侧重于脱敏牙膏。
