All of the listed conditions contribute to excessive bleeding during tooth extraction except _______________?
Show answer Hide answer
Answer: C. Anti thrombin – III deficiency
Explanation
Antithrombin III deficiency is a hypercoagulable state predisposing patients to thrombotic events. Deficiency of this anticoagulant protein increases clotting risks rather than bleeding tendencies. Patients suffer from venous thromboembolism instead of excessive bleeding during surgical procedures. Antithrombin III naturally inhibits thrombin and other coagulation factors to prevent clots. Inherited or acquired deficiencies disrupt normal hemostatic balance toward thrombosis. Anticoagulant therapy is required to manage patients with thrombotic diathesis.
Dental extractions in these patients require careful management of thrombosis risks. Clinicians must distinguish between bleeding disorders and hypercoagulable medical states. Understanding coagulation pathways prevents inappropriate administration of bleeding therapies. Hemophilia A involves Factor VIII deficiency which causes severe bleeding during extractions. Hemophilia B results from Factor IX deficiency leading to prolonged surgical bleeding. Von Willebrand disease impairs platelet adhesion and causes excessive mucosal bleeding episodes.
