Abstract
We report a case of complex odontoma that had unique radiological features. A 25-year-old man was referred to the Department of Dentistry and Oral Surgery, Sapporo General Hospital because of swelling and pain at the right side of the mandible. Panoramic radiographs showed a lesion with a mottled appearance over an impacted wisdom tooth. Computed tomographic examination clearly showed a lowdensity mass containing some cavernous-bone-like radiopacities. The mass was diagnosed to be a mandibular tumor and was removed surgically. The impacted wisdom tooth was then extracted. Histopathological examination of the mass revealed a complex odontoma, which was not suspected before operation. To our knowledge, there have been no previous reports of complex odontoma associated with the features of this case. We therefore describe and comment on this quite rare case.
