Correct answer: C — Odontome
C. Odontome is correct. UK Royal College of Surgeons guidance identifies odontomes as the most common odontogenic tumours, although biologically they are considered hamartomas rather than true neoplasms. The wording “classified within the odontogenic tumour group” therefore includes odontomes. Ameloblastoma is the most common benign odontogenic neoplasm and would be correct if the question specifically excluded hamartomatous lesions. Odontogenic myxoma, cementoblastoma and ameloblastic fibroma are recognised benign odontogenic tumours but occur less frequently than odontomes.
