Detection of leachables and cytotoxicity after exposure to methacrylate- and epoxy-based root canal sealers in vitro. -

Abstract Root canal sealing materials may have toxic potential in vitro depending on the cell line, cytotoxicity assay, material chemistry, and degree of polymer curing. The aims of the present study were to detect leaching components from epoxy- or methacrylate-based root canal sealers and to investigate the degree of cytotoxicity after exposure to extracts from […]
