Uncontrolled bleeding during endodontic treatment as the first symptoms for diagnosing von Willebrand's disease. A case report.

Von Willebrand's disease has been established as the most common hereditary hemorrhagic disease. Endodontic treatment, when possible, rather than extraction is the treatment of choice in patients suffering from such a disease. A case is presented in which, during regular endodontic treatment, uncontrollable bleeding occurred, suggestive of a generalized bleeding disorder. A thorough hematologic examination revealed von Willebrand's disease, which the patient was not aware of. The dental surgeon can play an important role in the diagnosis and treatment of such patients.
