[Tooth extraction and anticoagulants].

Introduction: The purpose of this study was to show the possibility of extracting teeth without modifying the anticoagulant treatment (anti-platelet and anti-vitamin K agents).

Material And Method: Two hundred patients underwent dental extraction from May 2003 to July 2006 without modifying their anticoagulant treatment; only 137 of them were hospitalized. Most of the teeth were extracted under local anesthesia, and hemostatic pad were inserted in the sockets without suture.
