Correct answer: A — Patient-specific bitewing radiographs based on risk

Bitewing frequency should be based on caries risk, clinical findings, and expected diagnostic yield, not a fixed interval. A panoramic radiograph is not an adequate substitute for detecting early interproximal caries. The pearl is that radiographs require both justification and optimisation for the individual patient.
