Abstract
We evaluated and analyzed the oral management methods for tooth extraction of patients receiving anti-platelet drug therapy who sought medical and dental treatment at our hospital. Generally there is no established guideline, criteria or index to discontinue the administration of antiplatelet drugs for tooth extraction, even though there are values indicated by the TT-INR for Warfarin. On the other hand, there have been recent publications concerned with the risk of complications resulting from the discontinuation of anti-coagulant drugs. Therefore we have extracted tooth without discontinuing the administration of anti-platelet drugs at our institution for some years. From our experiences and retrospective evaluation and analyses of 28 patients (34 teeth) receiving anti-platelet drug therapy who underwent tooth / teeth extractions between April 2004 and October 2005, our findings suggested and revealed how to manage these patients without major post extraction complications. The method of management was as follows. First the bleedings time (Duke method) was determined / measured as the index of anti-coagulant efficacy / ability. Following tooth extraction, sutures were placed and a protector was utilized with a hemostatic drug for wound the wound to heal. With this management method, we had no experience of prolonged bleeding and no complications. From these results, it is suggestive that tooth extraction is possible to be performed for patients receiving anti-platelet drug therapy without discontinuing anti-platelet drug therapy with proper oral management.
