The management of necrotic immature permanent teeth has always been a challenge to endodontists. Various treatment modalities have been tried and tested for achieving a successful outcome. Revascularisation is one among these treatment options, which is gaining widespread attention among endodontists. The growing body of evidence demonstrating the success of revascularisation has led to different variations of this treatment option. Clinicians have over time used different scaffolds such as blood clot, collagen, platelet-rich fibrin (PRF) and platelet-rich plasma for revascularisation. This case report outlines the management of immature maxillary central incisors with pulp necrosis and large periapical lesions in a 19-year-old female patient with a modified technique of revascularisation by combining PRF and blood clot. At the end of 12 months, the patient was completely asymptomatic along with regression of the periapical lesions.
坏死未成熟恒牙的治疗一直是牙髓病医生面临的挑战。为了取得成功的治疗效果，人们尝试并测试了各种治疗方法。牙髓血管再生术就是这些治疗选择之一，它在牙髓病医生中受到广泛关注。越来越多的证据表明牙髓血管再生术取得了成功，这导致了该治疗方法的不同变体。随着时间的推移，临床医生使用了不同的支架材料，如血凝块、胶原蛋白、富血小板纤维蛋白（PRF）和富血小板血浆来进行牙髓血管再生。本病例报告概述了一名19岁女性患者，采用结合PRF和血凝块的改良牙髓血管再生技术，对患有牙髓坏死和大根尖周病变的未成熟上颌中切牙进行的治疗。在12个月结束时，患者完全无症状，根尖周病变也有所消退。
