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.
