Micropush-out bond strengths of gutta-percha versus thermoplastic synthetic polymer-based systems – an ex vivo study Ureyen Kaya B et al. - To compare the interfacial strength and failure mode of root fillings consisting of different technique–material combinations...The push-out bond strengths of Resilon/Epiphany combinations were lower than those of gutta-percha/conventional root canal sealer combinations. Core materials and sealers may affect the push-out bond strengths of root canal filling materials [more...]
