Which radiographic approach is most appropriate for a young CHILD in primary dentition with closed posterior contacts?

  1. Posterior bitewings when proximal surfaces cannot be examined visually
  2. A full-mouth series of 18 films routinely
  3. A panoramic at every recall regardless of need
  4. No imaging is ever acceptable in children
Show answer and explanation

Correct answer: A. Posterior bitewings when proximal surfaces cannot be examined visually

Selection criteria base pediatric imaging on need; for a child with closed contacts, posterior bitewings detect interproximal caries with minimal exposure.Other options: Routine large surveys or panoramics at every visit overexpose children; complete avoidance of imaging is not appropriate when disease is suspected.Key exam takeaway: Image children by selection criteria; bitewings when contacts are closed and surfaces cannot be seen.
