The ultimate goal of an endodontic treatment is to eliminate infection, thoroughly clean and disinfect the root canal system, and prevent reinfection. Although endodontic procedures generally demonstrate high success rates, failures may still occur due to factors such as inadequate obturation or overextension of root-filling materials. Gutta-percha extrusion beyond the apex can lead to persistent inflammation and compromise the healing. This case report presents a 12-year-old girl with a two-month history of continuous pain and swelling in the maxillary anterior region. The patient had a history of dental trauma and previous root canal treatment and retreatment for tooth 21. Clinical and radiographic findings revealed periapical radiolucency with incomplete and over-extruded obturated material. An attempt to remove the extruded material using Hedstrom files under a Dental Operating Microscope (DOM) was unsuccessful, and persistent symptoms necessitated surgical intervention. This case presents the clinical challenges associated with an over-extended obturation and the limitations of nonsurgical retreatment in managing such conditions. Surgical endodontics, guided by American Association of Endodontists (AAE) protocols, can effectively manage persistent symptoms associated with over-extruded filling material. Timely intervention and adherence to clinical protocols are critical in ensuring successful long-term outcomes.
牙髓治疗的最终目标是消除感染,彻底清洁和消毒根管系统,并防止再次感染。尽管牙髓治疗程序通常显示出较高的成功率,但由于诸如充填不充分或根充材料超充等因素,仍可能出现失败情况。牙胶尖超出根尖可导致持续性炎症并影响愈合。本病例报告介绍了一名12岁女孩,上颌前部持续疼痛和肿胀两个月。该患者有牙齿外伤史,之前对21号牙进行过根管治疗和再治疗。临床和影像学检查发现根尖周透射区,充填材料不完整且超充。尝试在牙科手术显微镜(DOM)下使用赫氏锉去除超充材料未成功,持续的症状需要手术干预。本病例展示了与超充相关的临床挑战以及非手术再治疗在处理此类情况时的局限性。根据美国牙髓病学家协会(AAE)的方案进行的外科牙髓治疗,可以有效地处理与超充充填材料相关的持续症状。及时干预并遵循临床方案对于确保长期成功结果至关重要。
