Objective: To test the ability of Bio‐Oss ® in inducing growth factors and proinflammatory cytokines that may have a role in inflammation after grafting, bone resorption, remodeling and in the homeostasis of osteoblasts. Material and methods: Normal human osteoblasts were seeded in Petri dishes containing granules of Bio‐Oss ® , cells were harvested after confluency and RNA was extracted. Reverse transcriptase polymerase chain reaction was performed using specific primers for osteonectin, bone sialoprotein (BSP), bone morphogenetic protein (BMP)‐2 and BMP‐7, platelet‐derived growth factor (PDGF), interleukin 6 (IL‐6), tumor necrosis factor α (TNF‐α) and integrin β1. Glycerol‐3‐phosphate dehydrogenase was used as the housekeeping gene and normal human osteoblasts grown on Petri dishes without Bio‐Oss ® granules were used as negative controls. Results: Osteoblast grown on Bio‐Oss ® showed a normal RNA expression of osteonectin, integrin β1 and PDGF. However, compared with control osteoblasts it showed a reduced expression of BSP, BMP‐2 and BMP‐7, IL‐6 and TNF‐α. Conclusions: Our findings further support the evidence that Bio‐Oss ® is an excellent biomaterial that does not enhance the production of proinflammatory cytokines. To cite this article:
