The Role of CBCT

Role of CBCT in guided endodontics

In guided endodontic treatment, cone beam computed tomography (CBCT) plays a crucial role in enhancing the precision and accuracy of the procedure.

CBCT imaging provides clinicians with detailed three-dimensional information about the root canal system, enabling them to develop effective treatment plans and navigate complex anatomical structures with confidence.

Unlike traditional two-dimensional imaging techniques (e.g. periapical radiographs), CBCT allows for a comprehensive evaluation of the teeth and surrounding structures in high resolution.

This detailed visualization enhances the clinician’s understanding of the canal anatomy, allowing them to identify calcifications, hidden canals, and other complexities that may affect treatment outcomes.

By incorporating CBCT into guided endodontics, clinicians can accurately assess the dimensions, position, and angulation of the canals, facilitating precise treatment planning. This imaging modality helps in determining the optimal access point, designing custom 3D printed guides, and selecting appropriate instruments for the procedure.

During treatment, CBCT imaging enables real-time navigation and verification, allowing the clinician to monitor the progress and make any necessary adjustments. This dynamic feedback ensures the accurate placement of files and irrigation solutions, reducing the risk of errors and complications.

Furthermore, CBCT imaging aids in post-treatment evaluation, enabling clinicians to assess the quality of the canal filling and ensure the absence of any untreated or missed canals.

This evaluation contributes to the long-term success of the endodontic treatment by identifying potential areas of concern and allowing for timely intervention.

Case Selection Criteria for Guided Endodontics

When managing severely calcified canals, it is important to carefully select cases that are suitable for guided endodontics.

Clinicians should consider factors such as the degree of canal calcification, the presence of any complex anatomical variations, and the overall prognosis of the tooth.
