HIGHLIGHTSPOBT in endodontic research predicts the clinical behavior of endodontic material s .
Introduction : There is limited literature on the impact of testing variables on the push‐out bond test ( POBT ) .
This review identified design s of the POBT used in the endodontic literature and aim ed to determine which experimental variables may influence the push‐out bond strength ( POBS ) .
Effect of placement technique on the push-out bond strength of calcium-silicate based cements.
The purpose of this study was to evaluate the effects of ultrasonic and manual placement techniques on the push-out bond strength of Biodentine and MTA with and without calcium chloride .  One hundred and twenty mid-root slices from forty freshly extracted single-rooted human m and ibular premolar teeth were instrumented and r and omly divided into six groups ( n=20 ) according to the filling material and placement technique applied , as follows : G1 : MTA-manual compaction , G2 : Biodentine-manual compaction , G3 : MTA+5 % CaCl2-manual compaction , G4 : MTA-ultrasonic activation , G5 : Biodentine-ultrasonic activation , G6 : MTA+5 % CaCl2-ultrasonic activation . The push-out bond strengths were measured using an Instron testing machine . Data were analyzed using twoway analysis of variance ( ANOVA ) with Bonferroni correction . The ultrasonic activation significantly enhanced the bond strength values of the material s. Biodentine presented higher bond strength values than that of MTA groups . The addition of CaCl2 to MTA did not improve the bond strength of the material
