Fracture toughness of two dentin adhesives

Nov 30, 2017 by in Dental Materials Comments Off on Fracture toughness of two dentin adhesives

Abstract Purpose Test the hypothesis that a self-etching adhesive is more likely to fail at the dentin-adhesive interface than an etch-and-rinse adhesive. Materials and methods Forty-eight composite-dentin short rod chevron-notched…

Expression of CYP450-2E1 and formation of 2,3-epoxymethacrylic acid (2,3-EMA) in human oral cells exposed to dental materials

Nov 30, 2017 by in Dental Materials Comments Off on Expression of CYP450-2E1 and formation of 2,3-epoxymethacrylic acid (2,3-EMA) in human oral cells exposed to dental materials

Abstract Objectives Methacrylate-based (co)monomers released from dental composites can be, metabolized in vivo to methacrylic acid (MA). MA can be further oxidized to the toxic 2,3-epoxymethacrylic acid (2,3-EMA) by cytochrome…
