The aim of this paper is to present two methods of revascularization done in traumatized immature, nonvital anterior teeth using platelet-rich fibrin (PRF) and natural blood clot as a scaffold material. This was performed after disinfection of the root canal space using tri-antibacterial paste. In one tooth, PRF prepared from autologous blood was placed in the canal and in the other tooth, natural bleeding was induced to obtain a fresh blood clot. The patient was recalled regularly at 1, 3, 6, 9, and 12 months' interval for evaluation. After 12 months, on clinical examination, both teeth showed negative response to percussion and palpation tests but positive response to cold and electric pulp tests. On radiographic examination, the tooth treated with PRF exhibited comparatively faster root lengthening, complete closure of the root apex, more thickening of the root dentinal walls, and narrowing of root canal space compared to conventionally revascularized tooth.

本文旨在介绍两种对受创伤的未成熟、无活力的前牙进行血管再生的方法，使用富含血小板纤维蛋白（PRF）和自然血凝块作为支架材料。这是在使用三联抗菌糊剂对根管空间进行消毒后进行的。在一颗牙齿中，将由自体血液制备的PRF置于根管内，而在另一颗牙齿中，诱导自然出血以获得新鲜血凝块。定期召回患者，间隔1、3、6、9和12个月进行评估。12个月后，临床检查发现，两颗牙齿对叩诊和触诊测试均呈阴性反应，但对冷测和牙髓电活力测试呈阳性反应。影像学检查显示，与传统血管再生的牙齿相比，用PRF治疗的牙齿表现出相对更快的牙根延长、根尖完全闭合、牙根牙本质壁增厚更多以及根管空间变窄。Nagaveni NB、Poornima P、Mathew MG，《富血小板纤维蛋白在创伤性未成熟坏死前牙血管再生中的应用比较评估：病例报告》。《国际临床儿科牙科学杂志》2020年；13(1):98 - 102。
