Abstract

Cone-beam computed tomography (CBCT) has revolutionized the diagnostic and therapeutic approach in endodontics, particularly when dealing with complex clinical scenarios. This lecture will explore how CBCT can enhance the detection of hidden anatomy, resorptive lesions, vertical root fractures, and pathology undetectable on conventional 2D radiographs. Through clinical cases and evidence-based discussion, we will examine how 3D imaging impacts treatment planning and decision-making, including retreatments, surgical endodontics, and management of calcified canals. Emphasis will be placed on the integration of CBCT with digital workflows, including guided endodontics, artificial intelligence for image interpretation, and 3D analysis for surgical planning. By understanding when and how to utilize CBCT effectively, clinicians can significantly improve the predictability and outcomes of endodontic treatment.

Learning Objectives

By the end of this lecture, participants will be able to:

• Discuss the indications and limitations of CBCT in endodontic diagnosis.
• Explain how CBCT aids in the identification of complex root canal anatomy.
• Demonstrate how CBCT influences treatment planning in retreatment and surgical cases.
• Discuss the integration of CBCT into digital and guided endodontic workflows.
• Explain the role of 3D imaging in detecting vertical root fractures and resorptive defects.
