FIRST PARAGRAPH: Odontomas are hamartomas of odontogenic epithelium and ectomesenchyme, separated into compound and complex types. Both considered as a developmental anomaly, compound odontomas show diminutive tooth-like structures (Figures 1A and 2A), while complex odontomas show a haphazard aggregate of enamel and dentin (Figures 1B and 2B). Odontomas are considered to be one of the most common odontogenic tumors, with most presenting in the first 2 decades of life without sex predilection. Compound odontomas are more common in the anterior maxilla, while complex odontomas are more common in the posterior mandible (Figure 1B). The lesions are usually asymptomatic, detected on routine dental imaging studies, with a few cases reported in Rubinstein-Taybi syndrome. Radiographic features are considered diagnostic, with tooth-shaped structures surrounded by a radiolucent zone in compound odontomas versus a radiodense mass with a radiolucent zone seen in complex odontoma. Simple excision is curative without risk of recurrence.
