Complete root coverage of denuded root surface using expanded polytetrafluoroethylene membrane in conjunction with tetracycline root conditioning and fibrin-fibronectin glue application: case reports.

A new surgical technique can promote complete root coverage in deep and wide recessions. A root isolation procedure with expanded polytetrafluoroethylene membrane is combined with tetracycline treatment of the root surface and fibrin-fibronectin glue application. Treatment of two patients resulted in the disappearance of the anatomic defect and an increase in the amount of keratinized gingiva.
