Case 15 : Compound odontoma
Case 50 : Compound odontoma
Definition: Odontomas are the most common odontogenic tumor. Some believe that these lesions are actually hamartomas. The maxilla is more often involved than the mandible.
Most cases are diagnosed before age 20. Odontomas are either classified as compound or complex.
Radiographically a homogeneous radio-opacity is a complex odontoma and a lobulated radio-opacity is likely to be compound odontoma.
Grossly and microscopically, compound odontomas are arranged to suggest teeth while complex odontomas show sheets of dentin, cementum and enamel epithelium arranged haphazardly.
The treatment of odontoma is simple curettage and these lesions have no recurrence.
