Whenever endodontic therapy is performed on mandibular posterior teeth, damage to the inferior alveolar nerve or any of its branches is possible. Acute periapical infection in mandibular posterior teeth may also sometimes disturb the normal functioning of the inferior alveolar nerve. The most common clinical manifestation of these insults is the paresthesia of the inferior alveolar nerve or mental nerve paresthesia. Paresthesia usually manifests as burning, prickling, tingling, numbness, itching or any deviation from normal sensation. Altered sensation and pain in the involved areas may interfere with speaking, eating, drinking, shaving, tooth brushing and other events of social interaction which will have a disturbing impact on the patient. Paresthesia can be short term, long term or even permanent. The duration of the paresthesia depends upon the extent of the nerve damage or persistence of the etiology. Permanent paresthesia is the result of nerve trunk laceration or actual total nerve damage. Paresthesia must be treated as soon as diagnosed to have better treatment outcomes. The present paper describes a case of mental nerve paresthesia arising after the start of the endodontic therapy in left mandibular first molar which was managed successfully by conservative treatment.
每当对下颌后牙进行牙髓治疗时，都有可能损伤下牙槽神经或其任何分支。下颌后牙的急性根尖周感染有时也可能干扰下牙槽神经的正常功能。这些损伤最常见的临床表现是下牙槽神经感觉异常或颏神经感觉异常。感觉异常通常表现为灼痛、刺痛、麻刺感、麻木、瘙痒或任何与正常感觉不同的情况。受累区域的感觉改变和疼痛可能会干扰说话、进食、饮水、剃须、刷牙以及其他社交互动活动，这会对患者产生困扰。感觉异常可以是短期的、长期的甚至是永久性的。感觉异常的持续时间取决于神经损伤的程度或病因的持续存在。永久性感觉异常是神经干撕裂或实际完全神经损伤的结果。一旦诊断出感觉异常，就必须立即进行治疗，以获得更好的治疗效果。本文描述了一例在左下颌第一磨牙牙髓治疗开始后出现的颏神经感觉异常病例，该病例通过保守治疗成功治愈。
