The aim of this study was to investigate the effects of calcium silicate-based products on cytotoxicity in the 3T3 fibroblast and gelatinolytic activity of matrix metalloproteinases (MMPs). 3T3 fibroblasts were incubated directly with Ortho Mineral trioxide aggregate (MTA), BioAggregate, Biodentine, MTA Plus, MTA Angelus and MTA Cerkamed for 24 hours and seven days. The cytotoxicity was determined using an MTT assay. Supernatants were collected to determine MMP-2 and MMP-9. Data were analysed using IBM SPSS 22. Seventh day extracts of Ortho MTA and Biodentine showed reduced cell viability. Specific characterization of MMPs in cell culture demonstrated that MMP-2 (62 kPa) in the cell culture supernatants by gelatin zymography showed induced expression in four out of seven groups by 3T3 cells. No MMP-9 expression was observed. The cytotoxicity of materials revealed a significant difference in cell viability between the groups on the first and seventh days. The results of this study revealed minor cytotoxic effects for Ortho MTA and Biodentine. This study suggests that endodontic sealers induced production of MMP-2. MMP-9 might be expressed in small amounts when compared with MMP-2.
