Iatrogenic perforation is caused by the degradation of the dentin root floor or wall and the overlying cementum. This condition frequently arises from improper post-space preparation, root canal negotiation and preparation, and the use of misaligned burs or mechanical instruments during endodontic access. Proper management is essential; otherwise, it could lead to the need for tooth extraction. Management of iatrogenic perforation can be challenging. In this case report, a strip perforation on an upper anterior tooth was addressed for tooth rehabilitation using tricalcium silicate-based cement and a flexible glass fiber post. This approach aims to restore the tooth's function, structural integrity, and aesthetics while minimizing complications.
