Traumatic injuries to dentition can initiate either a resorptive or calcific pulpal response. In the sequelae of calcific degeneration, the clinical crown frequently becomes discolored, requiring an aesthetic correction to restore the tooth to its natural color. Four potential solutions are currently available to achieve this goal. The learning objective of this article is to describe the etiology of calcific metamorphosis, discuss the four potential solutions, and present the responses of endodontists polled as to the treatment indications. While the posterior dentition may experience the identical pathologic response to trauma and crown discoloration, this article focuses on the restoration of the anterior dentition. Several cases are presented to illustrate the four treatment modalities, and recommendations for follow-up of traumatic injuries are indicated.
牙列的创伤性损伤可引发吸收性或钙化性牙髓反应。在钙化变性的后遗症中，临床牙冠常变色，需要进行美学矫正以恢复牙齿的自然颜色。目前有四种潜在的解决方案可实现这一目标。本文的学习目标是描述钙化性变形的病因，讨论这四种潜在的解决方案，并介绍参与调查的牙髓病医生对治疗指征的反应。虽然后牙列可能对创伤和牙冠变色有相同的病理反应，但本文重点关注前牙列的修复。文中展示了几个病例以说明这四种治疗方式，并给出了创伤性损伤随访的建议。
