摘要
年轻恒牙出现牙髓病变及根尖病变，因其根尖尚未发育完全，常规根管治疗预后差，在治疗上通常采用根尖诱导成形术及根尖屏障术。根尖诱导成形即通过药物诱导牙根持续发育或者形成钙化屏障，但是治疗周期较长，存在根折危险。而且根尖屏障术可以一次性完成，使得年轻恒牙根尖孔闭合，却无法促进牙根的生理性发育。最近几年出现了牙髓再血管化，这引起人们普遍重视的新型治疗手段。本文观察了牙髓再血管化在牙髓炎-根尖周炎患者中的应用效果，以期能为青年恒牙牙髓炎和根尖周炎指征的选择准则提供一些参考，并为青年恒牙的临床治疗提供新的思路和治疗手段。

Abstract
Young permanent teeth with pulp and apical lesions often undergo apical induction and barrier surgery due to incomplete apical development and poor prognosis after conventional root canal treatment. Root apex induction is the process of inducing sustained root development or forming a calcified barrier through medication, but the treatment cycle is long and there is a risk of root fracture. Moreover, apical barrier surgery can be completed in one go, closing the apical foramen of young permanent teeth, but it can not promote the physiological development of the root. In recent years, pulp revascularization has emerged as a new treatment method that has attracted widespread attention. This article observes the application effect of pulp revascularization in patients with pulpitis periapical periodontitis, in order to provide some reference for the selection criteria of pulpitis and periapical periodontitis in young permanent teeth, and to provide new ideas and treatment methods for the clinical treatment of young permanent teeth.
Key words： Revascularization of dental pulp; Pulpitis; Periapical periodontitis; Permanent teeth
