BACKGROUND/AIM: Zoledronic acid (ZA) treatment of in vitro cultured osteoblasts (OB) results in reduction in viability, proliferation and differentiation. These effects are slightly attenuated when platelets-rich fibrin and plasma (PRF and PRP) are added. However, it is still unknown whether application of PRP/PRF on ZA-treated OB in a 3D-environment would influence the viability in relation to 2D-cultivation.
MATERIALS AND METHODS: Non-treated and ZA-treated OB were cultivated in 2D conditions or seeded in a 3D collagen scaffold with and without PRP/PRF. MTT test was carried out after 5 days of colonization. 4,6-diamidino-2'-phenylindole, dihydrochloride (DAPI)-staining was performed in OB grown in 3D scaffolds to ensure spatial distribution of OB.
RESULTS: ZA led to a significant reduction in cell viability compared to the control group. Addition of either PRF or PRP to the 3D colonized and ZA-treated OB significantly enhanced their survival and viability in relation to 2D monolayer cultivation.
CONCLUSION: The use of 3D-scaffolds has a positive effect on OB viability, and stimulation by PRF and PRP may provide a therapeutic approach to transfer these results into clinical routine for the treatment of patients with bisphosphonate related osteonecrosis of the jaw (BR-ONJ).
