Infection of the root canal system following dental trauma induces pulp and periapical disease and prevents healing of previously healthy pulp. A clinical goal in treating trauma is the maintenance of pulp vitality, and clinicians should be aware of factors that influence pulp healing. The learning objective of this article is to review the factors and techniques that influence pulp vitality and examine the influence pulp has on the healing of adjacent tissues. The potential routes for bacterial infection of the root canal system are discussed, with the clinical crown as the primary portal of entry. Uncomplicated and complicated crown fractures, as well as the crown-root and root fractures, are reviewed. Complications in pulp healing include canal obliteration, disturbed root development, apexogenesis, apexification, and the various forms of resorption.
牙外伤后根管系统感染会引发牙髓和根尖周疾病，并阻碍先前健康牙髓的愈合。治疗外伤的一个临床目标是维持牙髓活力，临床医生应了解影响牙髓愈合的因素。本文的学习目标是回顾影响牙髓活力的因素和技术，并研究牙髓对相邻组织愈合的影响。文中讨论了根管系统细菌感染的潜在途径，以临床冠作为主要入口。对简单和复杂的冠折、冠根折和根折进行了综述。牙髓愈合的并发症包括根管闭锁、牙根发育障碍、牙根形成、根尖诱导成形术以及各种吸收形式。
