Abstract:

BACKGROUND: Platelet-rich fibrin (PRF) prepared by autologous blood has become the hotspot in regeneration and repair of soft tissues.
OBJECTIVE: To compare the effect of two kinds of PRFs on the proliferation activity of human gingival fibroblasts (HGFs), so as to provide reference for the selection of oral soft tissue regeneration and repair materials in the clinic.
METHODS: Healthy gingival flaps from eight patients were collected when mandibular impacted teeth were removed. HGFs were obtained using tissue explant method, and then identified. The venous blood of the corresponding patients was drawn and made into advanced PRF and PRF, respectively, and passage 5 HGFs were divided into advanced PRF, PRF and blank groups for culture. The cell proliferation activity was detected by cell counting-kit 8 assay at 1, 3, 5, and 7 days.
RESULTS AND CONCLUSION: The HGFs were positive for Vimentin staining and negative for Cytokeratin staining. Two kinds of PRFs were prepared successfully. The advanced PRF exhibited the deeper color, more thick membrane and better flexibility compared with the general PRF. Cell counting-kit 8 assay results revealed that at 1 day after culture, there was no significant difference in the proliferation activity among groups (P > 0.05). At 3 days, the cell proliferation activity in the advanced PRF and PRF groups was significantly higher than that in the blank group (P < 0.05). At 5 and 7 days, the order of cell proliferation activity was as follows: advanced PRF group > PRF group > blank group (P < 0.01, P < 0.05). To conclude, both advanced PRF and PRF can increase the proliferation activity of HGFs, especially the former.
