When pulp tissue becomes necrotic in immature teeth, the prognosis of the teeth is compromised. Disinfection of the root(s) presents several challenges including difficulties in cleaning and shaping large canals with open apices, obturation of canals with open apices, and potential root fractures caused by thin and/or weakened root walls. Regenerative endodontic procedures may increase the prognosis of the compromised immature tooth by re-establishment of a functional pulp tissue that fosters continued root development and immune competency. This article reviews the literature related to and discuss considerations for regenerative endodontic procedures and how these procedures may increase the prognosis for immature teeth with necrotic pulp tissue.
当未成熟恒牙的牙髓组织发生坏死时，患牙的预后会受到影响。根管消毒面临诸多挑战，包括清洁和预备根尖孔开放的粗大根管困难、充填根尖孔开放的根管以及因根管壁薄和/或根管壁薄弱导致的潜在牙根折断。再生性牙髓治疗程序可通过重建功能性牙髓组织促进牙根继续发育和免疫功能，从而改善预后不良的未成熟恒牙的预后。本文回顾了与再生性牙髓治疗程序相关的文献，并讨论了其相关注意事项，以及这些程序如何改善牙髓坏死的未成熟恒牙的预后。
