The major considerations in restoring the pulp chamber following bleaching of endodontically treated anterior teeth include aesthetics, function, appropriate endodontic access preparation, amount of remaining tooth structure, type of restorative material, prevention of microleakage, and prevention of iatrogenic perforation. The learning objective of this article is to review the considerations that must be made when placing aesthetic restorations in the pulp chamber and access opening of endodontically treated teeth following intracoronal bleaching. The advantages and disadvantages of the proposed techniques and materials are discussed, as are the methods for avoiding excessive removal of the tooth structure. Two case reports are used to demonstrate the clinical procedures. The authors suggest placing white gutta-percha stopping material in the pulp chamber and a composite restoration in the access opening following root canal treatment and/or bleaching procedures in the anterior dentition.
对经牙髓治疗的前牙进行漂白后恢复髓腔时的主要考虑因素包括美观、功能、合适的牙髓治疗入口预备、剩余牙体组织量、修复材料类型、防止微渗漏以及防止医源性穿孔。本文的学习目标是回顾在对经牙髓治疗的牙齿进行冠内漂白后，在髓腔和入口处放置美观修复体时必须考虑的因素。讨论了所提出的技术和材料的优缺点，以及避免过度去除牙体组织的方法。使用两个病例报告来展示临床操作过程。作者建议在前牙进行根管治疗和/或漂白程序后，在髓腔内放置白色牙胶封闭材料，并在入口处进行复合树脂修复。
