摘　　要：恒牙根折是牙外伤常见类型之一,其预后受诸多因素影响,大多数观点认为拔牙是其主要治疗方案。然而,随着对根折牙愈合的生物学基础的深入认识,国际牙外伤协会(IADT)在2020年发布的新版牙外伤指南中提出了不同看法,牙髓完整、牙周基础条件好的根折牙,根折线处硬组织愈合发生率非常高,通过适当的临床措施,根折牙可以达到保留天然牙的目标。本文在文献查阅基础上系统阐述了根折牙愈合的生物学基础、愈合方式,以及根折牙的治疗策略。Permanent root fracture is a prevalent form of dental trauma,and its prognosis is influenced by numerous factors.While tooth extraction is commonly considered as the primary treatment option,the new dental trauma guidelines released by the International Association of Dental Trauma(IADT)presents a different perspective.For teeth with fractured root but intact pulp and good periodontal condition,hard tissue healing is probably to occur at the fracture line,so that they are likely to be preserved through appropriate clinical measures.This article systematically elucidated the biological basis,mechanisms of healing,and treatment strategies for teeth with fractured root based on a comprehensive literature review.
