Dental trauma occurs frequently in children and often can lead to pulpal necrosis. The occurrence of pulpal necrosis in the permanent but immature tooth represents a challenging clinical situation because the thin and often short roots increase the risk of subsequent fracture. Current approaches for treating the traumatized immature tooth with pulpal necrosis do not reliably achieve the desired clinical outcomes, consisting of healing of apical periodontitis, promotion of continued root development, and restoration of the functional competence of pulpal tissue. An optimal approach for treating the immature permanent tooth with a necrotic pulp would be to regenerate functional pulpal tissue. This review summarizes the current literature supporting a biological rationale for considering regenerative endodontic treatment procedures in treating the immature permanent tooth with pulp necrosis.
牙外伤在儿童中经常发生，且常常会导致牙髓坏死。恒牙但牙根未发育完全时发生牙髓坏死是一种具有挑战性的临床情况，因为牙根薄且通常较短会增加后续牙根折断的风险。目前治疗牙髓坏死的未发育成熟恒牙的方法不能可靠地实现预期的临床效果，这些效果包括根尖周炎的愈合、促进牙根的持续发育以及恢复牙髓组织的功能能力。治疗牙髓坏死的未发育成熟恒牙的最佳方法是使功能性牙髓组织再生。本综述总结了当前的文献，这些文献支持在治疗牙髓坏死的未发育成熟恒牙时考虑采用再生性牙髓治疗程序的生物学原理。
