A 16-year-old female methamphetamine addict presents for the first time with rampant caries. What radiographic series is MOST appropriate?

  1. Panoramic only
  2. Full mouth series (FMX)
  3. Bitewing radiographs only
  4. CBCT
Show answer and explanation

Correct answer: B. Full mouth series (FMX)

  • A. Incorrect. A panoramic alone is a good survey but lacks the detail of individual periapical radiographs needed to assess the extent of rampant caries and periapical status of each tooth.
  • B. Correct. A FULL MOUTH SERIES (FMX) — periapical radiographs of all teeth plus bitewings — is indicated for a new patient with a history of rampant caries, especially with drug-induced ('meth mouth') rampant decay. FMX provides the most comprehensive periapical and interproximal information for treatment planning.
  • C. Incorrect. Bitewings only show posterior interproximal regions and provide insufficient information for a comprehensive new patient examination with rampant caries.
  • D. Incorrect. CBCT is indicated for specific 3D assessment needs (implants, complex surgical cases) — not routine caries evaluation.
