CBCT is particularly indicated in which scenarios?

• A. Routine screening for caries.
• B. Soft tissue imaging.
• C. Routine bitewings for children.
• D. Implant planning, pathology assessment, complex root canal anatomy, impactions.

Answer: (D)

CBCT is used when you need precise 3D visualization of hard tissue structures and their spatial relationships, something 2D radiographs can’t reliably show. For implant planning, you must evaluate bone quantity and quality, the exact proximity to the inferior alveolar canal or sinus, and plan angulation and distance for a safe, predictable outcome—CBCT provides accurate measurements and virtual planning that 2D images can’t. In pathology assessment, 3D imaging helps delineate the extent and borders of a lesion and its relationship to adjacent anatomy, which guides diagnosis and treatment planning. Complex root canal anatomy often involves extra canals, unusual curvatures, or calcifications that are hard to detect on 2D views; CBCT reveals these details to inform access, cleaning, and obturation strategies. For impactions, understanding the tooth’s exact position, angulation, and relation to neighboring teeth and vital structures is crucial for surgical planning and risk assessment, and CBCT offers that comprehensive view. These scenarios contrast with routine caries screening, soft tissue imaging, or routine bitewings for children, where the benefit of 3D imaging is not justified due to higher radiation dose, limited soft tissue contrast, and the effectiveness of standard 2D techniques in these contexts.
