Gardner's syndrome: a case report.

Gardner's syndrome is characterised by polyposis coli associated with multiple hard and soft tissue tumours including osteoma and odontoma. The major significance of the condition lies in the gastrointestinal polyposis which usually undergoes malignant change by the fourth decade. Extra-intestinal components may be apparent before those in the bowel, and their early detection may lead to appropriate evaluation and life saving treatment. A case is reported to demonstrate how important it is for general dental practitioners to be aware of the clinical and radiological characteristics of Gardner's syndrome.
