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 ) .
The effect of blood contamination on dislocation resistance of different endodontic reparative materials.
This study evaluated the retention characteristics of ProRoot mineral trioxide aggregate ( MTA ) , RetroMTA , Supra MTA , and Biodentine bio material s used to repair furcation perforations contaminated with blood . Furcal perforations measuring 1.3 mm in diameter and 2 mm in height were created in 96 m and ibular first molar teeth , which were then r and omly divided into the following two groups ( n = 48 ) : contaminated ( + ) or non-contaminated  ( - ) with blood . The groups were subdivided into four groups ( n = 12 ) according to the material used ( ProRoot MTA , RetroMTA , Supra MTA , and Biodentine ) to seal the perforations . The sample s were allowed to set for 14 days and were then subjected to push-out testing . The results were analyzed using ANOVA , and the failure modes were examined using a surgical microscope . ProRoot MTA ( + /- ) and RetroMTA ( + /- ) exhibited superior bond strength values ; in addition , there were no significant differences among these groups ( P > 0.05 ) . Biodentine ( + ) showed intermediate values that were sometimes statistically similar to the ProRoot MTA ( + /- ) and RetroMTA ( + /- ) groups ( P > 0.05 ) and , at other times , the Biodentine ( - ) and Supra MTA ( + /- ) groups ( P > 0.05 ) . The lowest bond strength values were shown by the Biodentine ( - ) and Supra MTA groups ( P > 0.05 ) . " Adhesive failure mode " was the most frequently observed type for all tested material s. Blood contamination did not affect the dislocation resistance of material
