A case of a dentigerous cyst associated with an odontoma in the anterior maxilla

A dentigerous cyst associated with an odontoma in the left anterior maxilla is reported. The patient was referred to our hospital because of pain in the left anterior maxilla. Radiographic examination showed a cystic lesion with punctate opaque foci around the crown of an impacted supernumerary tooth. Histopathological examination revealed that the cyst wall was lined by non-keratinized squamous epithelium, and a small tooth-like structure was seen in fibrous connective tissue.
