Abstract

Medication-related osteonecrosis of the jaw is a rare but severe complication with challenging treatment protocols. Cold atmospheric plasma (CAP) has shown promising effects in wound healing, cell proliferation and viability. This study investigated the effect of CAP on osteoblasts in a culture medium containing bisphosphonates. Pilot study was designed to determine the optimal setting of CAP. MG-63 cells were exposed to zoledronic acid at a concentration of 10 micromolar for 72 h. Study groups with the best MTT assay results, were chosen for assessing OPG and RANKL genes by RT-PCR. Cell viability was significantly higher in groups 9 kV.1 mm.90 s, 10 kV.1 mm.60 s, and 12 kV.1 mm.60 s (P < 0.05). Expression of RANKL in these groups was significantly lower than the positive control group (medium culture without zoledronic and plasma treatment) and higher than the BP group (culture with zoledronic without plasma treatment), except for the 12 kV.1 mm.60 s group, which did not differ significantly from the positive control group (P > 0.05). OPG decreased in all test groups compared to BP (p < 0.05), except for the 12 kV.1 mm.60 s group, which did not significantly differ from BP (P > 0.05). RANKL/OPG ratio in groups 9 kV.1 mm.90 s and 12 kV.1 mm.60 s significantly increased compared to BP (P < 0.05).CAP treatment may enhance the viability of osteoblasts exposed to bisphosphonates, increase their activity levels, enhance osteoclast activity, and improve bone turnover rates. © The Author(s) 2024.
