Autologous platelet-rich plasma (PRP) for local application in periodontal regeneration.Ⅰ、the isolation of PRP and its effects on the proliferation of periodontal ligament fibroblasts(PDLFs).;

Safe, effective approaches for periodontal regeneration are the focus of scientists research around the periodontal area.

AIM:To observe and evaluate the effects of cells-scaffolds tissue engineering on the periodontal regeneration,and to estimate the feasibility of the autogenous periodontal ligament cells(PDLCs) and nano-Hap-collagen (nHAC) as the seed cell and the scaffold material for periodontal tissue engineering.

A review of amelogenin on clinincal application study in periodontal tissue regeneration;

Rresearch development of enamel matrix proteins and their effects in periodontal tissue regeneration;

The results showed that periodontal tissue in the wound healing source of the four types of cells, only periodontal ligament cells with the capacity of periodontal tissue regeneration.

Objective To observe clinic curative effect on treating serious periodontitis with BAM artificial bone by periodontal guided bone regeneration(PGBR) technique in one year.

Collagen membrane used for guided periodontal tissue regeneration;

Objective: The objective of the study was to explore the biocompatibility,biodegradability ,hemostatic and biological effects of chitosan-PVA-cm-chitosan membranes(C-CM), for the possibility of using C-CM membrane in guided tissue regeneration.
