BACKGROUND

Iatrogenic complications such as accidental perforation of the root or the floor of the pulp chamber may occur.

CASE REPORT

Patient was referred for root canal retreatment of the mandibular left second molar with periapical lesion evidenced through radiographic examination. During post removal, iatrogenic perforation occurred at the mesial face of the distal root. After clinical localization of the perforation and bleeding control, MTA was applied. In a second appointment, the root canal filling was removed and the chemical-surgical retreatment of the canals was performed, followed by the obturation with gutta-percha and sealer. Patient returned after three days reporting no pain. After 6 months, 3, 7 and 10 years of follow-up.

CONCLUSION

Absence of pain, normal periodontal probing and lack of radiolucent area at the region of perforation and the periapices were detected, which evidenced the successful repair of the tooth.

背景

可能会发生医源性并发症，如意外穿通牙根或髓室底。

病例报告

患者因下颌左侧第二磨牙根尖周病变前来进行根管再治疗，通过影像学检查得以证实。在取出桩核时，远中根的近中面发生医源性穿孔。在对穿孔进行临床定位并控制出血后，应用了矿物三氧化物凝聚体（MTA）。在第二次就诊时，取出根管充填物并对根管进行化学 - 手术再治疗，随后用牙胶和封闭剂进行充填。患者三天后复诊，称无疼痛。经过6个月、3年、7年和10年的随访。
