Correct answer: E — Radiographs must be justified by clinical findings

Canadian radiation safety principles require justification and optimisation, so imaging should be based on clinical findings, risk, and diagnostic need rather than a fixed interval. Patient preference matters for consent but does not replace the dentist's duty to prescribe radiographs appropriately. The pearl is that recent images should be requested where possible and new exposures should follow ALARA-style principles.
