Abstract Objective To compare the effects of titanium-prepared platelet-rich fibrin (T-PRF) and leukocyte platelet-rich fibrin (L-PRF) on osteoblasts. Methods Venous blood samples were collected from ten volunteer patients to obtain T-PRF and L-PRF. The T-PRF group was labelled as Group T, the L-PRF group as Group L, and the control group, which includes only osteoblasts, was Group K. PRF samples were added to cultured osteoblast cells and cell proliferation was assessed using an MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide) assay. The effect of different groups on osteoblast proliferation was observed for 72 h and the results were analysed statistically. Additionally, real-time polymerase chain reaction (RT-PCR) was conducted to evaluate gene expression levels of COL1A1, ALP, OCN, and RUNX2 within 48 h. Results We found that the MTT results at 24 h were significantly lower than those at 48 and 72 h (p = 0.036 and p 0.05). Conclusions In this study, we investigated the effects of T-PRF and L-PRF on osteoblast proliferation over a 72-hour period. Both groups improved osteoblast proliferation, however T-PRF group showed a consistent increase in osteoblast proliferation up to 72 h, in contrast to the L-PRF group. No differences in gene expression were found. However, osteoblastic marker genes can be significantly expressed over longer time periods. Therefore, long-term studies are needed.
