Tooth avulsion represents the most complicated dental injury, and the classic treatment is tooth replantation. The most common sequelae are pulp canal calcification (PCC) and pulp necrosis. The presence of pulp necrosis after PCC is reported in up to 30% of the cases and is a challenge due to the difficulty of endodontic treatment. This case report describes the surgical treatment of a replanted tooth presenting PCC and periapical pathology eight years after the trauma. An endodontic surgery was performed to remove the apical granuloma, to prepare the apical root, and to seal the apical region with an endodontic cement. In a three-year follow-up, there was an absence of inflammatory signs and symptoms or apical lesion. This report shows the importance of close follow-up after dentoalveolar injuries. After the initial dental trauma and its consequences to pulpal tissues, the executed procedures allowed a favourable outcome.
牙齿脱位是最复杂的牙外伤，经典的治疗方法是牙齿再植。最常见的后遗症是牙髓腔钙化（PCC）和牙髓坏死。据报道，PCC后牙髓坏死的发生率高达30%，由于根管治疗困难，这是一个挑战。本病例报告描述了一颗外伤八年后出现PCC和根尖周病变的再植牙的外科治疗。进行了根管外科手术，以切除根尖肉芽肿，预备根尖牙根，并用根管粘固剂封闭根尖区域。在三年的随访中，没有炎症体征和症状或根尖病变。本报告显示了牙槽损伤后密切随访的重要性。在最初的牙齿外伤及其对牙髓组织造成的后果之后，所实施的治疗程序取得了良好的效果。
