A radiograph shows a mass associated with a tooth. It is classified as which type of mass?
Show answer and explanation
Correct answer: B. Hamartoma
- A. A teratoma contains elements from multiple germ layers (ecto, meso, endo) in the wrong location — typically found in gonads/mediastinum; not how odontomas are classified.
- B. An ODONTOMA is classified as a HAMARTOMA — a disorganized overgrowth of tissue elements that are native to the site (enamel, dentin, cementum, pulp tissue). Hamartomas are not true neoplasms; they represent developmental malformations of tissues normally found at that location. Odontomas are the most common odontogenic tumors and are hamartomatous lesions.
- C. Neoplasm implies abnormal autonomous cell proliferation — odontomas are not true neoplasms.
- D. A choristoma is normal tissue in an abnormal LOCATION (ectopic tissue) — not a tooth-associated mass.
