Gardner's dento-maxillary stigmas in patients with familial adenomatosis coli.

ABSTRACT

Fifty patients with familial adenomatosis coli (FAC) studied by panoramic tomography (PTG) showed osteomatous jaw changes in 82% as compared with 10% in matched controls. Supernumerary teeth, compound odontomas and/or impacted teeth were seen in 30% of the patients compared with 4% of the controls. A correlation was found between dental abnormalities and the large number of osteomas. The results support the view that both osteomas of the jaws and dental abnormalities are features of FAC. PTG of the jaws may serve as a valuable tool for early detection of FAC by oral surgeons, at least in the case of the most striking changes (about 20%).
