This study assessed the dose-dependent effect on the cytotoxicity of BioRoot RCS (BR) and Endosequence BC (BC) sealers in human bone marrow mesenchymal stem cells (hMSCs) compared to those of the AH Plus sealer. Cells were exposed to different dilutions of extracts from freshly prepared sealers (1:2. 1:8. 1:32). https://www.bekindtopets.com/hot-mega-Allflex-840-USDA-HDX-EID-Tags-20-Bag-save-big/
