Abstract

This study evaluated the push-out bond strength of 0%, 0.5%, 1.0%, 2.0% and 3.0% (w/w) casein phosphopeptide-amorphous calcium phosphate (CPP-ACP)-modified calcium silicate-based cements (CSCs). The push-out bond strength of a trial MTA was also compared with two CSCs (Biodentine™ and Angelus® MTA). Three hundred 1 mm thick horizontal root sections were prepared from 60 singlerooted human teeth. The canal space of each section was enlarged and filled with the cements. The sections were stored in a phosphate buffer solution. After incubation for 2 months, the push-out bond strength was measured and the data were analyzed using one way analysis of variance followed by Tukey’s test. The additio..
