What are typical indications for using CBCT in endodontics?

• A. Complex root canal anatomy
• B. Calcified canals
• C. Unusual canal morphology
• D. Pre-surgical planning and assessment of lesion extent

Answer: (D)

The main point is that CBCT is most valuable in endodontics for planning surgery and assessing the full extent of a lesion. The three-dimensional view reveals exactly how large a lesion is, where it sits in relation to the cortical bone, and its proximity to vital structures such as the inferior alveolar nerve or maxillary sinus. This information helps you choose the most appropriate treatment approach, design the surgical plan (flap design, osteotomy location), and anticipate potential complications, leading to safer, more predictable outcomes. While CBCT can also aid in cases with complex canal anatomy or calcifications, those scenarios are more about informing diagnosis and treatment planning in challenging anatomy. The key, typical use that most directly influences the decision to intervene surgically is pre-surgical planning and evaluating lesion extent.
