The effects of calcium silicate cement/fibroblast growth factor-2 composite on osteogenesis accelerator in human dental pulp cells

Background/purpose: To examine the effects of fibroblast growth factor-2 (FGF-2)/calcium silicate (CS) cement on material characters and in vitro primary human dental pulp cell (hDPC) behavior. Materials and methods: Setting time and diametral tensile strength (DTS) of CS and CS/FGF-2 composite were measured. PrestoBlue assay was used for evaluating primary hDPC proliferation. Alkaline phosphatase and osteocalcin expression in HDPCs cultured on the specimens were determined by enzyme-linked immunosorbent assay. One-way analysis of variance was used to evaluate the significance of the differences between the mean values. Results: Setting time and DTS of CS were not significantly different (P > 0.05) between CS hydration with H2O or FGF-2. Cell proliferation and osteogenic properties increased significantly (P
