Histologically there are two types of odontomas; compound odontomas consist of all dental tissues resembling a tooth-like structure and complex odontomas are present as disorganized mass (2).
Large retrospective studies have shown that the site of predilection of compound odontomas are the anterior maxilla, whereas complex odontomas preferably develop in the mandible in various sites (8).
9 with a peak of between age 10 to 19 while compound odontomas were diagnosed at a younger age than were complex odontomas and they are often diagnosed during explorations because of a delay tooth eruptions or incidentally on control radiographs (7,10).
Compound odontomas often occur in the incisor and canine areas of the maxilla.
5) Compound odontomas resemble normal teeth of various shapes and sizes, but complex odontomas appear as amorphous masses.
A presumptive diagnosis of compound odontoma is usually determined by radiographic appearance alone and is seldom confused with any other lesion.
Histologically, the compound odontoma will often have normal appearing enamel, dentin, cementum, and pulp.
Clinical features: The relative frequency of complex odontoma among odontogenic tumors vary between 5% and 30% which means that this lesion is one of the most commonest odontogenic lesion/malformation, only superseded in frequency by the compound odontoma, which is 9% to 37%.
