What is a key advantage of CBCT over conventional 2D radiographs for dental pathology assessment?

• A. Lower cost
• B. No radiation exposure
• C. Faster data processing
• D. Provides 3D localization and volumetric data

Answer: (D)

Three-dimensional localization and volumetric data are the key advantages of CBCT for dental pathology assessment. This capability lets you see a lesion or abnormality in all three spatial dimensions, so you can determine its true extent, depth, and exact relationship to nearby structures like the inferior alveolar canal, floor of the maxillary sinus, or cortical plates. With 2D radiographs, structures can obscure or overlap one another, making it hard to judge how far a lesion extends buccolingually or to gauge its proximity to critical anatomy. CBCT’s multiplanar views and 3D reconstructions remove that guesswork, enabling more accurate diagnosis and more precise treatment planning. In contrast, the other options aren’t advantages of CBCT: it generally costs more, delivers a higher radiation dose than a single 2D radiograph, and data processing can be slower rather than faster.
