Online published on 5 January, 2012. Abstract Introduction Dental treatment performed in patients receiving continuous oral anticoagulant drug therapy is becoming increasingly common in dental offices. For these patients it is imperative to carry out careful anamnesis, as well as a multiprofessional clinical evaluation with regard to the risk and control of hemorrhagic or thromboembolic episodes. Objectives and Material and Methods The aim is to evaluate post-extraction hemorrhagic or thromboembolic episodes in patients who have been on anticoagulant medications for an uninterrupted period of 48 months. Results Among the 108 patients evaluated, 215 extractions were performed in which there was only one case of post-operative bleeding. Warfarin was used by 98 patients, Warfarin associated with salicylic acetic acid by 9 patients, and salicylic acetic acid in only 1 patient. The serologic tests performed, INR (International Normalized Ratio) ranged from 0.8 to 4.9, with a mean of 3.15. Conclusion Extractions in patients on oral anticoagulants must be performed in the least traumatic manner possible. It is not necessary to stop anticoagulant therapy to perform extractions. Local hemostatis techniques, such as obliterative sutures alone are sufficient to prevent hemorrhagic complications. Top Keywords Anticoagulant, Hemorrhage, Tooth Extraction, Hemostasis. Top |
