Well-circumscribed mixed-density lesion coronal to an unerupted permanent tooth.

The case reported is that of an ameloblastic fibro-odontoma in an 11-year-old male. The radiographic and clinical findings were typical, appearing as a well-defined radiolucent-radiopaque lesion coronal to an erupting permanent tooth. Treatment consisted of surgical removal (enucleation) of the hard and soft tissue mass. Recurrence of the lesion is not anticipated.
