Abstract:
The effects of polytetrafluoroethylene (e PTFE) membrane on periodontal ligament cell (PDLC) growth and periodontal tissues and new cement regeneration were studied, and the prospects of clinical application of e PTFE membrane were discussed. The results showed that PDLC grew well on the e PTFE membrane and no toxicity or inhibition was found. Close adhesion of the cells to the membrane was observed by scanning electron microscope. Histological studies suggested that the peculiar porous structure of e PTFE membrane protects and promotes healing of alveolar bone defect when the membrane edge was sealed perfectly on the crown side,exhibiting inhibition of growth of epithelium towards tooth root. The membrane was beneficial to regeneration of new alveolar bone and cement and establishment of new adhesion,and was regarded as a good substitute of old materials.
