Introduction: Obturation of the canal space, efficient disinfection, and thorough canal debridement are essential components of endodontic therapy success. A crucial first step is biomechanical preparation.
Objectives: This study set out to assess various file systems' cleaning efficacy in terms of the thickness of dentin that remained after cleaning.
Objectives: The study's objective is to evaluate the fracture resistance of a tooth that has had endodontic treatment and has been rebuilt using various post and core systems.
Materials And Methods: Thirty-six extracted premolar teeth of similar sizes were picked, and at random, they were separated into three groups: group A received stainless-steel posts, group B received zirconia fiber posts, and group C received glass fiber posts. Dual-cured resin cement was used to cement each post.
