CBCT is particularly indicated for endodontic evaluation when there is a need to evaluate complex canal morphology, resorption, or unusual anatomy.

CBCT is particularly indicated for endodontic evaluation when there is a need to evaluate complex canal morphology, resorption, or unusual anatomy.

• A. For routine uncomplicated canals.
• B. For imaging without radiation concerns.
• C. When evaluating complex canal morphology or unusual anatomy.
• D. It should replace all 2D radiographs.

Answer: (C)

Understanding when to use CBCT in endodontics hinges on needing three-dimensional information to see what plain X-rays can miss. When there’s complex canal morphology, unusual anatomy, or resorption patterns, CBCT reveals the true layout of the root canal system, helps locate hidden or extra canals, shows curvature and branching that might not be visible on 2D images, and delineates the extent and boundaries of resorption or pathology. This 3D perspective can change treatment planning—such as where to access, how to negotiate specific canals, or how to manage resorptive defects—more reliably than two-dimensional radiographs alone. In contrast, for routine uncomplicated canals, conventional periapical radiographs usually provide sufficient information with lower radiation dose and cost. CBCT should not be used as a default replacement for all imaging or to avoid 2D radiographs; it’s reserved for cases where the additional 3D detail will meaningfully impact diagnosis or treatment decisions.
