ABSTRACT
Objective: The aim of this study is to evaluate the effects of platelet-rich plasma (PRP) on
the proliferation, migration, and attachment of cultured periodontal ligament (PDL)
cells. Materials and Methods: 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used
to assess number of PDL cells cultured in medium with or without PRP. Cell migration
toward medium with or without PRP was assessed using the Boyden chamber. Cell attachment
was assessed by counting cells on PRP or non-PRP coated dentin specimens. Group differences
were analyzed using two-way ANOVA at 0.05 significance level. Results: In the MTT and cell migration assay, the number of cells in 5% and 10% PRP-treated
groups were significantly higher than that in the non-PRP-treated group (P < 0.05). In the attachment assay, the number of cells on the dentin specimens in
10% PRP-treated group was significantly higher than that in the non-PRP treated group
(P < 0.05). Conclusion: PRP could stimulate proliferation, migration, and attachment of PDL cells.
