Odontoma is a mixed odontogenic neoplasm composed of epithelial and mesenchymal tissues. There are: compoundodontoma and complex odontoma. Compound odontoma appears to be a radiopaque mass composed of in-groupsmall teeth. Compound odontoma is generally found in the anterior maxilla, and is double in number than complexodontoma. Complex Odontoma appears to be an irregularly-shaped mass and an amorphous radiopaque image,which is often found in the posterior maxilla. Impacted mandibular third molars occur due to either insufficientspace for teeth to grow or improper dental position. Two cases of complex odontoma-generated impactedmandibular third molar were reported. Extirpation and extraction were performed on the impacted teeth.
