Pediatric Dentistry · single question
A 4-year-old child presents for a routine examination. No caries or abnormalities are found clinically, and the child has normal interdental spacing. What radiographic examination is MOST appropriate?
Show answer and explanation
Correct answer: D. No radiographs at this time
For a 4-year-old with no clinical caries, no abnormalities, and normal spacing, the ADA/AAP recommend no radiographs at this time. Radiographs should be taken based on clinical need and caries risk — not on a fixed schedule. With visible spacing between primary teeth, interproximal caries risk is low and clinical assessment is adequate. Bitewings are indicated when proximal surfaces cannot be clinically examined (teeth are in contact).
- A. ❌ A panoramic radiograph is not justified without clinical indication in this scenario.
- B. ❌ Even 1 bitewing is not justified when the child has spacing and no caries risk factors.
- C. ❌ 4 bitewings are not indicated in a low-risk 4-year-old with spacing and no clinical findings.
- D. ✅ CORRECT – No radiographs are indicated for a low-risk child with no clinical findings and natural spacing (open contacts visible).
