Relationship between Use of Aspirin and Post-Extraction bleeding Time: A Single Blind Study

Abstract

Background: The purpose of the study was to evaluate the effect of low dose aspirin before tooth extraction. Materials and Method: The study group consisted of 5, patients who were scheduled to undergo dental extractions. All patients were receiving 7, - 15, milligrams of aspirin daily on a regular basis. The authors randomly divided the patients into two groups: those who stopped the aspirin therapy before the procedure and those who continued the aspirin therapy. One hour before the procedures, all patients underwent a bleeding time test. Results: The mean (±Standard Deviation) bleeding time was 1.8±0.4, minutes for patients who stopped aspirin therapy one week before the procedure. For patients who continued aspirin therapy, the bleeding time was 3.1±0.6, minutes. However, both groups were within the normal bleeding time range and in both groups, a local hemostatic method was sufficient to control bleeding. No episodes of uncontrolled intra operative or postoperative bleeding were noted. Conclusion: Low-dose aspirin therapy should not be stopped before oral surgery. Local haemostasis is sufficient to control bleeding.
