In contribution to diverse techniques of bone reconstruction involving biomaterials in contemporary dentistry, this study aimed to evaluate the effect of the bone‐grafting materials Bio‐Oss ® and Cerasorb ® Dental M on the expression of cytokines associated with bone remodeling by human monocytes in vitro . Bio‐Oss ® and Cerasorb ® Dental M were incubated in separate culture media, and their supernatants were added to mononuclear cells of human peripheral blood, some of which had been stimulated with Porphyromonas gingivalis . The frequency of total monocytes and CD14 + monocytes producing cytokines interleukin 6 (IL‐6), IL‐8, IL‐10, IL‐12, and tumor necrosis factor alpha (TNF‐α) were determined by flow cytometry. One‐way analysis of variance with repeated measures, followed by Tukey's post hoc test, revealed that stimulation with P. gingivalis increased the expression of IL‐6 and IL‐8 and reduced the expression of TNF‐α compared to effects demonstrated in the control group ( p < 0.05). Adding biomaterial supernatants did not significantly affect the expression of any cytokine evaluated, however, either in the absence or in the presence of bacterial stimulation. Our data suggest that Bio‐Oss ® and Cerasorb ® Dental M neither stimulate cytokine production in human monocytes nor interfere with mechanisms of cell communication mediated by cytokines evaluated during stimulation with P. gingivalis . © 2016 Wiley Periodicals, Inc.
