Abstract

The purpose of this study was to evaluate the incidence of postoperative bleeding in patients treated with oral anticoagulant medication who underwent dental extractions without interruption of the treatment and to analyze the incidence of postoperative bleeding according to the International Normalized Ratio (INR) value. The 249 patients who underwent 543 dental extractions were divided into five groups: Group 1 with INRs of 1.5-1.99, Group 2 with INRs of 2-2.49, Group 3 with INRs of 2.5-2.99, Group 4 with INRs of 3-3.49 and Group 5 with INRs>3.5. The INR was measured on the day of the procedure. Local haemostasis was carried out with gelatin sponge and multiple silk sutures. Of the 249 patients, 30 presented with postoperative bleeding (12%): Group 1, three patients presented with bleeding (5%), Group 2, 10 patients (12.8%), Group 3, nine patients (15.2%), Group 4, five patients (16.6%) and Group 5, three patients (13%). The incidence of postoperative bleeding was not significantly different among the five groups. The value of the INR at the therapeutic dose did not significantly influence the incidence of postoperative bleeding. Thus, dental extractions can be performed without modification of oral anticoagulant treatment. Local haemostasis with gelatin sponge and sutures appears to be sufficient to prevent postoperative bleeding.
