Dental anomalies in familial adenomatous polyposis coli.
Forty-seven Danish and 50 Finnish patients with familial adenomatous polyposis coli (FPC) were studied by panoramic tomography (PTG) of the mandible, which showed dental abnormalities in 17% of the cases. Eleven patients (11%) had supernumerary teeth and/or compound osteomas, and nine patients (9%) had impacted permanent teeth. The frequency of the dental anomalies was statistically significantly higher in FPC patients than in the normal population; it is therefore concluded that this dental abnormality should be included in the list of extracolonic manifestations that may occur in any FPC patient. The frequency of dental anomalies was higher in Finnish than in Danish patients, probably owing to a higher frequency of extracolonic manifestations in the Finnish series.
