Microfibrillar collagen (Avitene) as a hemostatic agent in experimental oral wounds.

In dogs with experimentally created oral wounds, Avitene proved to be superior to Gelfoam or Surgicel as a topical hemostatic agent. No postoperative problems were encountered. All sites healed equally well and there was no discernible histological difference between results with Avitene and with the other agents.
