Best radiographic technique to determine the exact buccolingual position of a mesiodens?

  1. Panoramic radiograph
  2. Occlusal radiograph
  3. Periapical radiograph using SLOB rule
  4. CBCT (Cone Beam CT)
Show answer and explanation

Correct answer: D. CBCT (Cone Beam CT)

CBCT provides 3D localization — gold standard for exact position of mesiodens and relationship to adjacent roots. Particularly important for surgical planning in an 8-year-old. 2D techniques (SLOB, occlusal) help but lack precision for buccolingual localization.
