Background: Warfarin is the most common anticoagulant used worldwide. The present study was conducted to determine post extraction bleeding in patients on anticoagulant therapy. Materials & Methods: The present study was conducted on 260 patients of both genders (males- 120, females- 140) requiring dental extraction. In all patients medical, clinical, and radiographic assessment was performed before extractions. An INR was also done the same day of the procedure or within 24 hours. Patients were prescribed with antibiotics. All patients underwent extractions as following guidelines. Results: Mean INR score in patients with INR < 2.2 was 1.76 and in patients with INR > 2.2 was 2.84. Mean age was 66.4 years and 68.2 years in patients with INR < 2.2 and > 2.2 respectively. Males were 65 and females were 80 with INR < 2.2 and in patients with INR > 2.2 was 55 males and 60 females. Males were 5 and females were 7 with post extraction bleeding episodes. Common medical conditions were myocardial infarction in males (60) and females (75), atrial fibrillation in males (20) and females (30), stroke in males (10) and females (20), venous thromboembolis in males (15) and females (25) and vulvulopathy in males (15) and females (10). Conclusion: Careful assessment of medical condition is required in patients undergoing dental extraction. OACs dose needs to be modified accordingly.
