Radiology is an important component in diagnosis, monitoring and assessment of treatment outcome for endodontic diseases. The advent of cone- beam computed tomography (CBCT) offers three-dimensional accuracy of dento-maxillofacial structures and has been seen to overcome some limitations of 2D radiography. The indications for CBCT in endodontics are outlined in the position paper written by the American Academy of Endodontics and the American Academy of Oral and Maxillofacial Radiology. Advanced training and experience is needed for accurate interpretation of CBCT scans. Knowledge of the proper orientation of the imaged volume, image anatomy and pathological entities is vital for interpreting scans.
This table clinic presentation will:
1. Provide and demonstrate guidelines that can aid in interpretation with the use of a de-identified CBCT scan. 2. Demonstrate the advantages of CBCT images over periapical images for indications outlined below:
Teeth with the potential for extra canals and suspected complex morphology. Identification and localization of calcified canals. Detection of vertical root fracture. To assess endodontic treatment complications, such as overextended obturation material, separated endodontic instruments, and localization of perforations. For presurgical treatment planning to localize root apices and to evaluate the proximity to adjacent anatomical structures. For dentoalveolar trauma, root fractures and localized alveolar fractures. For localization and differentiation of external and internal resorptive defects.
3. Distinguish some non-pulpal pathological entities that can mimic endodontic periapical lesions with the use of radiographic images.
At the end of this presentation, clinicians will have a better understanding on how to interpret endodontic CBCT scans.
