Effectiveness of Guided Endodontics, Er:YAG Laser and Ultrasonic Techniques in Fiber Post Removal: A Micro-Computed Tomography Study

Description :

Forty-five oval canals with fiber posts underwent root canal preparation, post luting, and core buildup. Specimens were divided into guided endodontics, Er:YAG laser, and ultrasonic groups. Micro-CT scans evaluated coronal volume changes and residual luting material. Laser and ultrasonic groups were assessed for temperature, and all groups for procedure time.
