Inclusion Criteria:
- Selection of patients: Both genders, aged over 18 years, regardless of ethnicity, marital status, nationality, naturalness or profession, with non-valvular atrial fibrillation using dabigatran or rivaroxaban or apixaban or warfarin, under medical outpatient treatment or during the hospitalization period.
- Dentistry: Patients with indications of exodontia of one to three permanent adjacent teeth erupted in the maxilla or mandible due to extensive dental caries or periodontal disease.
Exclusion Criteria:
- Clinical: Patients on concomitant use of antiplatelet agents or heparin, pregnant and lactating patients, with coagulation disorders, severe chronic renal insufficiency (CrCl <30), severe hepatopathies and proven to be allergic to lidocaine and / or epinephrine.

Active Comparator
Rivaroxaban
Dabigatran and Apixaban
Warfarin
As the rivaroxaban is ingested 1x/day, the interval between a maximum peak concentration and the other peak is 24 hours. Therefore, the surgery will be performed between two peaks of maximum drug concentration, knowing that the maximum peak concentration is an average of two hours after ingestion. So the surgical procedure should be scheduled 14 hours (2 hours+ 12 hours) after the last medication intake.
As dabigatran and apixaban are taken 2x/day, the interval between two peak concentration is 12 hours.Taking into account the first two hours of maximum peak concentration and half the interval between two peaks (2 hours + 6 hours = 8 hours), the surgical procedure must be programmed eight hours after the last intake of medication.
The control group will consist of patients on chronic use of warfarin. The operation will be scheduled at any time, provided that the patient has INR value between 2.0 and 3.0 and test performed in maximum 15 days before surgery.
