Dental Management of Patients Undergoing Antithrombotic Therapy.

Abstract

For more than half a century, oral anticoagulant and antiplatelet therapy has been used to decrease the risk of thromboembolism, prolonging the lives of countless patients. Patients taking antithrombotic agents may be at risk of excessive hemorrhage. Dentists commonly see such patients, and this can pose a challenge, as adequate hemostasis is crucial for the success of invasive dental treatment. Many dentists refer these patients, as they lack understanding or fear uncontrollable bleeding during and after surgery. In this clinical review, we discuss the mechanisms of hemostasis, drugs that can interfere with these pathways and how to safely and effectively manage patients who are taking antithrombotic agents. We include which procedures are considered safe, which are riskier in terms of bleeding, what laboratory tests must be reviewed before treatment, drug interactions with commonly prescribed dental drugs, as well as agents that can aid in hemostasis. Although antithrombotics cause an increase in bleeding, there is general consensus that treatment regimens should not be altered before routine dental procedures when the risk of bleeding is moderate to low. Procedures that require drug alterations include extractions of more than 3 teeth, crown lengthening, open-flap surgery, surgical extractions and periodontal surgery.
