Repair or regeneration of the pulp, following trauma, is a part of the wound healing process. However, pulp necrosis or root resorption, whether partial or complete, might obstruct this process. Because of the neurovascular bundle at the apical foramen and the periodontal ligament, the pulp in this fragment generally remains normal when the apical fragment is not moved. We describe a mature upper left central incisor with a horizontal root fracture in the mid-third of the root and lateral luxation that healed on its own after undergoing a procedure called self-revascularization. The fracture was detected during a routine dental checkup on a tooth that was asymptomatic. Two tooth pieces with trabecular bone between them were discovered using periapical radiography and cone-beam computed tomography (CBCT). Therefore, the endodontic intervention was not needed. Regular follow-up after trauma is mandatory to evaluate any signs of pulp necrosis. CBCT can help assess healing and identify resorption.
外伤后牙髓的修复或再生是伤口愈合过程的一部分。然而，牙髓坏死或牙根吸收，无论是部分的还是完全的，都可能阻碍这一过程。由于根尖孔处的神经血管束和牙周韧带，当根尖碎片未移位时，该碎片中的牙髓通常保持正常。我们描述了一颗成熟的左上中切牙，牙根中部三分之一处有水平根折并伴有侧向脱位，在接受一种称为自我血管化的手术后自行愈合。该骨折是在对一颗无症状牙齿进行常规牙科检查时发现的。通过根尖片和锥形束计算机断层扫描（CBCT）发现了两个之间有小梁骨的牙片。因此，不需要进行牙髓治疗干预。外伤后定期随访对于评估牙髓坏死的任何迹象是必不可少的。CBCT有助于评估愈合情况并识别吸收情况。
