The native connective tissue attachment of the periodontium is known to be a complex consisting of gingival fibroblasts, periodontal ligament cells, gingival epithelial cells, cementum, alveolar bone and extensive extracellular matrix (collagen, glycoprotein and proteoglycans). The purpose of this study was to evaluate the effects of natural extracts on DNA, collagen and protein synthesis and inhibition of cytokine production in the gingival and periodontal ligament fibroblasts and gingival epithelial cells. Healthy gingival tissue was obtained from orthodontic treatment patients, and gingival epithelial cells, gingival fibroblasts and periodontal ligament cells were isolated and cultured from the samples. After treated with Ginseng protein, Pluronic F-68, Scutellariae Radix, centella asiatica, PDGF, IGF, DNA synthesis, total protein and collagen synthesis, and cytokine production of gingival epithelial cell, gingival fibroblast and periodontal ligamentcells were measured. MTT method for DNA synthesis, Peterkofsky and Dingerman method for total protein and collagen synthesis, and IL-1 ELISA kit for cytokine production were used. The proliferation of epithelial cells was enhanced in Centella asiatica, Ginseng protein, Pluronic F-68 and Scutellariae Radix. The activities of PDL cells were increased in PDGF, IGF, and Pluronic F-68. Higher collagen synthesis was observed in Scutellariae Radix and total protein synthesis was increased in Scutellariae Radix and PDGF. The inhibitory effects on IL-1, IL-6, $TNF-{\alpha}$ were observed in all exrracts.
