Altering anticoagulation therapy: a survey of physicians.

Patients who take antithrombotic medications, such as warfarin sodium or aspirin, are more likely than others to experience bleeding problems after some dental treatments. Withdrawing the medication before treatment, however, may place these patients at risk of medical complications. The authors surveyed physicians about the conditions under which such pharmacotherapies should be altered. They not only found a difference of opinion among the respondents, but also learned that many respondents misunderstood the nature of certain dental procedures and the likelihood that those procedures would cause significant postoperative bleeding.
