Odontomes are considered to be hamartomas rather than a true neoplasm. They are comparatively common odontogenic tumors, and may lead to interference with eruption of associated tooth. Compound odontomes are commonly seen in young adults, but if they occur in children they are usually associated with permanent dentition and prevent eruption of the associated tooth. We hereby report a case of large compound odontome in the mandibular body region of a 65-year-old woman. Because of difficulty in denture fabrication and associated pain on mastication, surgical removal of the lesion was done.
