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 novel chelating agents on the push-out bond strength of calcium silicate cements to the simulated root-end cavities.
To compare the effects of different chelating agents on the push-out bond strength of calcium silicate-based cements to the simulated root-end cavities . Root-end cavities were prepared on the roots of fifty extracted maxillary anterior teeth . The specimens were then r and omly divided into 5 groups ( n = 10 ) based on the final irrigation regimen : Group 1 : 17 % EDTA , Group 2 : 7 % maleic acid , Group 3 : QMix , Group 4 : 2.25 % peracetic acid ( PAA ) , Group 5 : 0.9 % saline . Then , the sample s from each group were subdivided into two groups ( n = 5 ) based on the apical filling material . In group 1 , root-end cavities of all sample s were filled with Biodentine and in group 2 , with MTA . Each sample was horizontally sectioned to produce two discs of ∼1 mm thick per specimen . The maximum load required for the dislodgement of 100 retrofillings was recorded . The specimens were examined under scanning electron microscope after debonding to assess the type of bond failure . Data were statistically analyzed using Kruskal Wallis and Mann Whitney U tests . Irrigation with saline result ed in higher bond strength compared to the other irrigants in the retro grade cavities obturated with MTA or Biodentine ( p < .05 ) . In MTA group , there was no significant difference between the test irrigants ( p > .05 ) . EDTA and PAA groups showed higher dislodgement resistance values than the other test irrigants , when Biodentine was used as a filling . The type of irrigation solution influences the bond strength of the root-end fillings
