Certain medical conditions and their respective treatments have often influenced dental treatments. Oral anticoagulant therapy (OAT) has been successfully used to reduce the risk of thromboembolism. Patients using oral anticoagulants often require dental surgical procedures. The pre-operative assessment of these patients submitted to oral surgery is a common and challenging problem. The aim of this study was to evaluate the hemorrhagic complications due to oral surgery in patients submitted to OAT without modifying the therapeutic regimen. The patients included in this study were undergoing OAT and required surgical procedures (extractions, alveoloplasties). A total of 73 interventions in 25 patients were made. The average INR during the pre-operative period was 2.59, ranging from 1.20 to 4.61. Only one patient (4%) presented, on the second day, a light hemorrhage, which was managed with local pressure. Therefore, patients in OAT that require dental extractions should not interrupt or alter the therapeutic regimen due to the low risk of bleeding and the potential risk of developing a thromboembolic accident. The incidence of hemorrhagic complications in this study was of 4%. Dental extractions are safe procedures for patients undergoing OAT, with INR values within the therapeutic interval recommended as ideal for the clinical conditions being treated, as long as they are associated to local hemostatic actions.
