A review of the literature on infection-related mental and inferior alveolar nerve paresthesia is given. This is followed by 2 case reports. The first case is of a mandibular left second molar in which a chloropercha overfill puff occurred in the vicinity of the inferior alveolar canal. The tooth remained asymptomatic until 2 and 1/2 yr later, when the periapical lesion enlarged and swelling, pain, and paresthesia developed. The paresthesia resolved 2 weeks following periapical surgery. The second case is of a mandibular right first premolar in which paresthesia began 1 day after the initial endodontic treatment. The intracanal medication was formocresol on a cotton pellet that was squeezed dry. The paresthesia was treated by irrigation, antibiotics, and dexamethasone. The paresthesia lasted 7 weeks, and when it resolved the root canal was filled with gutta-percha/eucapercha. Almost 9 months later, the tooth remained asymptomatic.
本文对感染相关的精神及下牙槽神经感觉异常的文献进行了综述。随后报告了2例病例。第一例是左下第二磨牙，在下牙槽管附近出现了氯仿牙胶超充团块。该牙一直无症状，直到2年半后，根尖病变扩大，出现肿胀、疼痛和感觉异常。根尖手术后2周感觉异常消失。第二例是右下第一前磨牙，在首次根管治疗后1天开始出现感觉异常。根管内用药是用棉球蘸甲醛甲酚并挤干。通过冲洗、抗生素和地塞米松治疗感觉异常。感觉异常持续了7周，消失后根管用牙胶/优卡因牙胶充填。近9个月后，该牙仍无症状。
