Clinical Trial Summary

The purpose of this study is to evaluate the safety of a protocol which does not suspend the new oral anticoagulants (dabigatran, rivaroxaban and apixaban) in front of dental extractions in patients with non-valvular atrial fibrillation.

Description:

The sample will be divided into three groups according to the pharmacokinetics of the oral anticoagulant: rivaroxaban 1x/day (group 1); dabigatran and apixabana 2x/day (group 2) and warfarin (control group). Extraction of one to three teeth will be scheduled, in the valley of the new oral anticoagulants' concentration, considered the period of smallest haemorrhagic risk without suspension. In group 1 the surgery will be scheduled 14 hours after the last intake, in group 2 the surgery will be scheduled 8 hours after the last intake, while the control group will undergo the procedure with INR values between 2.0 and 3,0. Hemostatic measures with tranexamic acid paste intra alveolar, suture and biological glue GRF® (gelatin, resorcinol and formaldehyde) and post operative care will be associated. The patients will be contacted after the procedure to inform the presence or absence of late bleeding. The patient should return 24 hours later to evaluate the surgical site. This protocol is based on Guidelines and scientific articles, pharmacokinetics and clinical experience of the authors.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	A bleeding event (incidence of postoperative bleeding events)	To evaluate the safety of a protocol regarding the risks of bleeding after dental extractions performed in patients with non-valvular atrial fibrillation in continuous use of the new oral anticoagulants, we compared the incidence of postoperative bleeding events after dental extractions between patients in use of new oral anticoagulants and those treated of warfarin without withdrawal of oral anticoagulant therapy.	7 days
