Guided Endodontics in the Management of Calcified Canals: A Case-Based Comparison of Static and Dynamic Navigation

Pulp canal obliteration remains one of the greatest challenges in endodontic practice, often transforming routine treatment into a technically demanding procedure with a substantial risk of iatrogenic errors. The inability to accurately locate the canal can result in excessive dentin removal, perforation, prolonged treatment time, and compromised prognosis. The emergence of guided endodontics has redefined the management of these complex cases by combining advanced imaging, digital planning, and navigational technologies to facilitate precise and conservative access.

This presentation showcases a series of clinically challenging cases of calcified canals successfully managed using guided endodontic techniques. The complete digital workflow—from cone beam computed tomography acquisition and virtual treatment planning to guided access preparation and canal negotiation—will be demonstrated, highlighting practical considerations that influence clinical success.

While static guidance offers a highly accurate, template-based approach for predetermined access, dynamic navigation provides real-time visualization of bur position, enabling intraoperative flexibility and enhanced operator control. Their respective indications, advantages, limitations, clinical accuracy, workflow efficiency, and learning curves will be critically discussed in the context of current scientific evidence and clinical application.

By integrating evidence with real-world clinical experience, this presentation aims to provide clinicians with a practical framework for selecting the most appropriate guided approach for managing calcified canals. As digital technologies continue to transform endodontic practice, guided endodontics represents a significant step toward safer, more predictable, and minimally invasive treatment of anatomically challenging teeth.
