“…The MTA Fillapex® endodontic sealer tested in the present study had no genotoxic effect on HGFs. Using a modified micronucleus test without cytokinesis-blocking, no mutagenicity of the cement was also detected in human fibroblast cell lines FG11 and FG15 [31] . Previously, neither regular nor white MTAs were found to be genotoxic in Chinese hamster ovary (CHO) cells or in vitro human peripheral lymphocytes obtained from 10 healthy volunteers.…”
