ObjectiveTo evaluate the cytoprotective effects of melatonin (MLT) on zoledronic acid (ZA)-treated human osteoblasts.MethodsHuman osteoblasts were exposed to ZA (1, 5, 10, 50, 100 and 300 μM) and MLT (1, 10, 50, 100 y 200 μM) for 24, 48 and 72 h of incubation, to evaluate their effects on cell viability.ResultsAs ZA concentration increased, greater reductions in cell viability of human osteoblasts were induced whether at 24, 48 or 72 h incubation. At 24 h incubation with MLT, greatest cell viability was obtained when low dose of MLT was applied (without significant differences); 48 and 72 h incubation presented the greatest cell viability with the highest MLT concentrations (100 and 200 μM). MLT at concentrations of 100 and 200 μM would appear to have a certain cytoprotective effect on ZA-treated human osteoblasts with low concentrations of ZA (1 y 5 μM), whether at 24, 48 or 72 h; however, at ZA concentrations â¥10 μM the possible cytoprotective effects of MLT were low at 24 h incubation.ConclusionsMLT has a cytoprotective effect on ZA-treated human osteoblasts and could represent a promising preventative alternative for patients at risk of bisphosphonate-related osteonecrosis of the jaw.
