Abstract
In this study, we evaluated the relationships between the doses of an antithrombotic drug during tooth extraction and postoperative bleeding in 45 patients.
Tooth extraction was performed in 19 patients under the maintenance doses of anticoagulants, and in 5 patients under the reduced doses or withdrawal of the drug, and no difficulties in hemostasis were observed. Although bleeding time was within 3 minutes in almost all patients who had taken an antiplatelet drug, only one patient showed a prolonged bleeding time (11 minutes and 30 second). However, no difficulties in hemostasis were observed in the 20 patients under the maintenance doses of an antiplatelet drug, or in 4 patients under the reduced doses or withdrawal of the drug.
Hemostasis could be obtained even in patients in whom tooth extraction was performed under the maintenance doses of an antithrombotic drug, by performing appropriate local treatment procedures such as suture.
In the tooth extraction in patients who had taken an antithrombotic drug, hemostasis was possoble by performing appropriate physical hemostatic procedures, and it was suggested that tooth extraction under maintenance doses was desirable, considering the risk that may be caused by the withdrawal of the drug.
