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 ) .
Influence of endodontic irrigants on resin sealer bond strength to radicular dentin.
The present study evaluated the influence of 2 % chlorhexidine and 2.5 % sodium hypochlorite on the resin sealer/dentin interface bond strength of AH Plus/gutta-percha and Epiphany/Resilon .  Seventy-two extracted bovine incisors were r and omly distributed into 6 groups according to irrigant and sealers : G(S+AH)=physiologic saline solution+AH Plus/gutta-percha ; G(S+Ep)=physiologic saline solution+Epiphany/Resilon ; G(H+AH)=2.5 % sodium hypochlorite (NaOCl)+AH Plus/gutta-percha ; G(H+Ep)=2.5 % NaOCl+Epiphany/Resilon ; G(C+AH)=2 % chlorhexidine (CHX)+AH Plus/gutta-percha ; and G(C+Ep)=2 % CHX+Epiphany/Resilon . After 7 days at 37 ° C and 100 % humidity , the roots were cut transversally on the long axis of the tooth in 0.8 mm (±0.09)-thick slices ; these slices were then subjected to the push-out test . Data were analyzed using a 2-way ANOVA and Tukey tests at 5 % significance . The AH Plus/gutta-percha groups showed significantly higher bond strength than the Epiphany/Resilon groups , regardless of the irrigant used ( p<0.001 ) . Sodium hypochlorite adversely affected bond strength in the AH Plus group , whereas chlorhexidine did not influence the push-out bond strength of either sealer ( p<0.05 ) . Two percent chlorhexidine did not adversely affect the bond strength of the sealers , whereas 2.5 % sodium hypochlorite solution damaged AH Plus/gutta-percha bond strength
