Objective: The aim of this study was to investigate the effects of a new Portland Cement formulation (CPM) comparing it to Angelus MTA on cell viability and IL-1b and IL-6 release by mouse fibroblasts. Methods: Poly- ethylene tubes filled with these materials were placed into 24-well cell culture plates with mouse fibroblasts. Empty tubes were used as control. After 24 hours, MTT assay was used to evaluate the cell viability. For cyto- kine assay, mouse fibroblasts were incubated in 24-well flat-bottom plates with set material disks at the bottom or without material, as control. After 24 hours, culture media were collected for cytokine evaluation by using ELISA. Results: CPM and Angelus MTA did not inhibit the cell viability. Both materials induced IL-6 and IL-1b release and the amount was statistically significant com- pared with the control group. Conclusions: Both mate- rials were not cytotoxic in fibroblast culture and induced IL-6 and IL-1b release.
