To evaluate the clinical and radiological results of a revascularization treatment done in a nonvital, immature permanent tooth using the amniotic membrane.
A 12-year-old boy reported with a complaint of pain in the lower left back tooth since 1 month due to dental caries. On clinical examination, the mandibular left second premolar was tender on percussion and discolored due to dental caries. Radiographic examination of the same tooth revealed open apex, thin root dentinal walls, and periodontal ligament widening. An access opening was prepared, necrotic pulp extirpated completely followed by thorough irrigation. After drying the canal, closed dressing with the 3-mix antibacterial paste was given for 15 days. After 15 days, the paste was removed and the amniotic membrane was placed inside the canal extending 1 mm beyond the apex and mineral tri-oxide aggregate was placed over this followed by sealing of the cavity. The patient was followed up at 1, 3, and 6 months for clinical and radiographic evaluation.
After 6 months, clinically the tooth found asymptomatic. Radiographic examination showed continued root elongation, closure in the periapical opening, thick root dentinal walls with narrowing of the canal space, and normal periradicular architecture.
Amniotic membrane can be used as a scaffold for revascularization in nonvital immature teeth.

评估使用羊膜对一颗非活髓、未成熟恒牙进行血管再生治疗的临床和影像学结果。
一名12岁男孩因龋齿自1个月前开始出现左下后牙疼痛。临床检查时，下颌左侧第二前磨牙叩诊疼痛，因龋齿变色。对同一颗牙齿进行影像学检查显示根尖孔开放、牙根牙本质壁薄以及牙周膜增宽。制备了开髓孔，彻底清除坏死牙髓，随后进行充分冲洗。干燥根管后，用三联抗菌糊剂进行封闭换药15天。15天后，去除糊剂，将羊膜置于根管内，超出根尖1毫米，然后在其上放置三氧化矿物凝聚体，随后封闭窝洞。在1、3和6个月时对患者进行随访，进行临床和影像学评估。
6个月后，临床上该牙齿无症状。影像学检查显示牙根持续伸长、根尖孔闭合、牙根牙本质壁增厚且根管间隙变窄，以及根尖周结构正常。
羊膜可作为非活髓未成熟牙齿血管再生的支架。
