Complex odontoma of the maxillary sinus: report of case.

During a screening examination for orthodontic evaluation and for possible partial anodontia, a large radiopaque mass was found in the right maxillary sinus of a 12-year-old boy. Further radiographic views were used to locate and establish a working diagnosis. The mass was removed with use of a standard Caldwell-Luc approach. It was diagnosed histologically as a complex odontoma.
