CBCT is particularly indicated when evaluating what aspects?

• A. Osseous changes of the TMJ and 3D bony anatomy; it is less informative for soft tissue.
• B. Soft tissue evaluation.
• C. Soft tissue aesthetics.
• D. Vascular anatomy.

Answer: (A)

CBCT is specialized for bone imaging, so its strongest use in evaluating the TMJ is to examine osseous changes and three-dimensional bony anatomy. The TMJ relies on detailed bone assessment to identify alterations such as condylar flattening, erosions, osteophyte formation, subchondral sclerosis, and overall condylar or fossa morphology, all of which CBCT can depict with high spatial resolution and the ability to reconstruct in 3D. While this modality excels at bone, its soft tissue contrast is limited, making it less informative for disc position, ligaments, muscles, or other non-bony structures. For soft tissue evaluation, MRI provides superior contrast and detail, which is why CBCT’s role is focused on osseous assessment rather than soft tissue or vascular mapping.
