Background: Platelet products play a fundamental role in the process of healing. The new generation of platelet-rich fibrin (PRF), namely advanced PRF (A-PRF), has different biological and mechanical properties compared to those of leukocyte-PRF (L-PRF). This study aimed to compare the effects of L-PRF and A-PRF on the viability and migration of human gingival fibroblasts (HGFs). Materials and Methods: In this in vitro study, the effects of A-PRF and L-PRF on the viability and migration of HGFs after 24 and 48 h were evaluated using the methyl thiazolyl tetrazolium assay. The viability of the negative control culture medium was considered to be 100%. The mean optical density of the test groups was divided by that of the negative control group and reported as percentage. One-way ANOVA was applied to assess the effects of time and type of PRF on the viability and migration of HGFs. Pairwise comparisons were made using the Tukey's test. Results: At 24 h, cell viability in the L-PRF group was significantly higher than that in the A-PRF group (P < 0.05). However, no significant difference was noted between the two groups at 48 h. At 24 h, L-PRF caused significantly higher cell migration compared to the negative control group, whereas at 48 h, both A-PRF and L-PRF significantly increased cell migration compared to the control group. Conclusion: Within the limitations of this study, L-PRF and A-PRF had significant effects on the viability and migration of HGFs. Further studies on these platelet concentrates are warranted.
