A patient for the FIRST TIME — what type of X-rays should be taken?
Show answer and explanation
Correct answer: C. Full mouth series (FMS) of periapical radiographs
- A. Bitewings show only the coronal portions and interproximal bone — they miss periapical pathology, root structure, and bone levels in the entire arch.
- B. CBCT has higher radiation dose than conventional radiographs and is indicated for specific clinical situations — it is NOT the standard initial radiographic survey for a new patient.
- C. For a NEW PATIENT, a FULL MOUTH SERIES (FMS) — consisting of 14-18 periapical radiographs — is the recommended complete radiographic survey. It provides: (1) periapical status of all teeth, (2) bone levels (combined with bitewings), (3) root morphology, (4) detection of pathology in all areas. This is the comprehensive baseline radiographic examination. Bitewings may be added for caries detection.
- D. A panoramic radiograph provides an overview but lacks the detail of periapical films — it is NOT sufficient as the ONLY radiographic examination for a new patient with teeth.
