Description

Odontoma is a tumor arising from the dental enamel, dentin and dental cementum where the majority is of the harmartoma type. At times, the components of the enamel epithelia may be identified at the marginal regions. We herein report a case of infantile odontoma with concomitant ameloblastoma that was histopathologically identified.<BR>A 9-year-old boy sought dental consultation at the Department of Dentistry and Oral Surgery, Toho Hospital with the chief complaint of abnormal tooth eruption of the anterior maxillary tooth. Clinical diagnosis for odotoma was established with radiographic examination. The lesion was enucleated under local anesthesia. Histopathological examination identified cellular foci of ameloblastoma in both the ondontogenic solid and soft tissues and was diagnosed as compound odontoma. The post-operative course has been uneventful.
