A revascularization procedure was shown to be the best alternative therapy for immature teeth with necrotic pulp and apical infection. A 12 year old female with a history of trauma to her upper central incisor and a sinus tract was referred for endodontic treatment. She was an active orthodontic patient and had undergone regenerative endodontic treatment for the past 2 years. Clinical examination revealed no response to sensibility, percussion, and palpation tests. The preoperative radiograph showed an open apex and apical rarefaction. The case was diagnosed as previously treated tooth with asymptomatic apical periodontitis. Regenerative endodontic retreatment was performed, and the case was followed for 3 years. Clinical, radiographic, and cone-beam computed tomography follow-up examination revealed an asymptomatic tooth, with evidence of periapical healing and root maturation.
对于牙髓坏死和根尖感染的未成熟恒牙，血管再生术被证明是最佳的替代治疗方法。一名12岁女性因上颌中切牙外伤史及窦道转诊接受牙髓治疗。她是一名正在接受正畸治疗的患者，过去两年接受过牙髓再生治疗。临床检查显示对牙髓活力、叩诊和触诊测试均无反应。术前X线片显示根尖孔开放及根尖区骨质稀疏。该病例被诊断为曾接受治疗的牙齿伴无症状性根尖周炎。进行了牙髓再生再治疗，并对该病例进行了3年随访。临床、影像学及锥形束计算机断层扫描随访检查显示该牙无症状，有根尖愈合及牙根发育成熟的迹象。
