Comparative evaluation of push-out bond strength of mta hp, white mta and biodentine - an in vitro study

Various materials have been used in managing perforations. MTA HP (Angelus, Londrina, Brazil), a more recent silicate-based cement material, was developed based on the biological and physical properties of calcium-silicate cements, claiming improved performance compared with traditional MTA. Although several studies have assessed the bond strength of MTA HP to dentin, none of them have evaluated the effect of blood contamination on the dislocation resistance of the new material. Therefore, the present study was designed to investigate the resistance to dislodgment provided by MTA HP. Biodentine (Septodont, St. Maur-des-Fossés, France) and White MTA (Angelus, Londrina, Brazil) were used as reference materials for the comparison.
