How do you determine the position of a mesiodens?
Show answer and explanation
Correct answer: A. CBCT
- A. Correct. CBCT gives true 3-D localization (bucco-palatal position, proximity to roots) — the most definitive for a supernumerary.
- B. A panoramic shows presence but distorts and superimposes — poor for precise localization.
- C. A single periapical is 2-D; two angled PAs (SLOB) can localize, but a single one cannot.
- D. An occlusal film helps with bucco-palatal localization but is inferior to CBCT for position.
