Abstract

Warfarin is an anticoagulant involved in the production of vitamin K dependent blood clotting factors. Dentists should be familiar with the appropriate assessment methods and considerations for the treatment of patients taking warfarin. Dental surgery with the moderate risk of bleeding can be performed without stopping the drug through preoperative examination of the INR(international normalized ratio) value and evaluation. When performing a surgery with a high risk of bleeding, it is necessary to evaluate whether the drug can be discontinued, what the duration is, and the risk of discontinuation. Hemostasis can be obtained by local methods in most cases of postoperative bleeding in patients taking appropriately adjusted doses of warfarin.
