Guided Endodontics: Advances, Necessity, and Clinical WorkflowIntroductionRoot canal therapy (RCT) aims to preserve healthy periradicular tissues by eradicating infection through thorough cleaning, shaping, and obturation of the root canal system. Calcified canals, often the result of trauma, aging, or chronic irritation, pose significant diagnostic and clinical challenges. Pulp canal obliteration (PCO) can occur in 15-40% of post-traumatic cases, rendering canals radiographically invisible and increasing the risk of procedural errors such as perforation, excessive dentin removal, and missed...
