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 ) .
Drying protocol influence on the bond strength and apical sealing of three different endodontic sealers.
The aim of this study was to evaluate the influence of drying protocol s ( DP ) on the apical sealing ( AS ) and on the bond strength ( BS ) of teeth filled with different  sealers .  The root canals of one hundred and fifty-six roots of maxillary canines were prepared with Reciproc rotary files ( R50 ) . The teeth were r and omly divided into four groups ( n = 39 ) , according to the DP : GI-paper points ; GII-70 % isopropyl alcohol + aspiration with NaviTip points ; GIII-95 % ethanol + paper points ; GIV-EndoVac + paper points . Each group was divided into subgroups , according to the sealer used : AH Plus , Sealapex and MTA Fillapex , using a single-cone technique . Evaluation of AS and BS was performed with fluid filtration ( FF ) and push-out ( PO ) methods , respectively . The PO test consisted of sectioning the roots , and subjecting a single slice from each third to testing and analysis for failure type . The data was su bmi tted to two-way and three-way variance analysis ( ANOVA ) and Tukey ( α = 5 % ) . The AS showed no drying protocol influence . The FF results revealed a statistically significant difference between MTA and Sealapex ( p < 0.05 ) sealers . The BS test values showed that there was no statistical significant difference among the canal thirds ( p > 0.05 ) , but that there was such a difference among the sealers ( p < 0.05 ) , among the protocol s ( p < 0.05 ) , and in the interaction between sealers and protocol s ( p < 0.05 ) . AH Plus revealed the highest BS values among the sealers ; the highest BS results for the sealers occurred with the specimens used with isopropyl alcohol , compared with ethanol and EndoVac
