Correct answer: B — CBCT assessment if it will alter surgical plan

Panoramic signs of close inferior alveolar canal relationship can justify CBCT if the result will change consent or surgical approach. Bitewings and cephalometrics are not appropriate for canal-root spatial assessment. The pearl is that imaging should support risk counselling and options such as coronectomy in selected cases.
