Endodontic therapy is indicated for cases of traumatic tooth dislocation associated with pulp necrosis and/or inflammatory resorption. Here we describe the management of a maxillary left lateral permanent incisor that suffered lateral luxation, leading to pulp necrosis and root resorption, in a 13-year-old boy. The traumatized tooth was treated successfully by intracanal medication with calcium hydroxide, 2% chlorhexidine gel and zinc oxide for 12 months without any need to change the dressing, followed by conventional root canal filling. The postoperative course was uneventful and a stable clinical outcome was obtained with evidence of periapical lesion repair and stabilization of the resorption process.
牙髓治疗适用于与牙髓坏死和/或炎性吸收相关的外伤性牙脱位病例。在此，我们描述了一名13岁男孩上颌左侧恒侧切牙发生侧方脱位，导致牙髓坏死和牙根吸收的治疗过程。通过根管内使用氢氧化钙、2%氯己定凝胶和氧化锌进行药物治疗12个月，无需更换敷料，随后进行常规根管充填，成功治疗了这颗受伤的牙齿。术后过程顺利，获得了稳定的临床结果，有根尖周病变修复和吸收过程稳定的证据。
