Abstract:
Objective: To evaluate the effects of expanded polytetrafluoroethylene (ePTFE) barrier membrane in guided periodontal tissue regeneration(GTR) . Methods:Nine patients with Ⅱ～Ⅲ furcation lesions were treated by guided tissue regeneration using ePTFE membrane. The membrane was retrieved 5 weeks after operation and examined by scanning electron microscopy (SEM) . Results:Large amount of lymphocytes were found on the external upper surfaces of ePTFE, with a little bacteria. The external lower surface of ePTFE was full of fibrocytes, red blood cells and lymphocytes.Conclusion:ePTFE membrane is biocompatible and can close the primary wound over a barrier which stops the downgrowth of junctional epithelium at the early stage of periodontal tissue repair after operation.
