Show answer and explanation
Correct answer: A. Sialolith
- A. Correct (per item). A submandibular sialolith can superimpose so that it appears 'half in, half out' of the mandible on a panoramic film.
- B. Incorrect. An osteoma is a bony outgrowth firmly part of the bone, not the superimposed pattern described.
- C. Incorrect. An odontoma is an intrabony tooth-like mass, not a partly extra-osseous superimposition.
