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 ) .
A novel polyurethane-based root canal-obturation material and urethane-acrylate-based root canal sealer-part 2: evaluation of push-out bond strengths.
We have developed a visible-light curable urethane-acrylate/tripropylene glycol diacrylate ( UA/TPGDA ) oligomer to serve as a root canal sealer and a zinc oxide/thermoplastic polyurethane ( ZnO/TPU ) composite to serve as a root canal obturation material . The purpose of this study was to compare the push-out bond strengths of the following 8 groups of material s : ( 1 ) Tubliseal + gutta-percha ( TB/GP ) ; ( 2 ) Tubliseal + Resilon ( TB/R ) ; ( 3 ) Epiphany + gutta-percha ( EP/GP ) ; ( 4 ) Epiphany + Resilon ( EP/R ) ; ( 5 ) EndoREZ sealer + EndoREZ cone ( ES/EC ) ; ( 6 ) EndoREZ sealer + ZnO/TPU ( ES/PU ) ; ( 7 ) UA/TPGDA + EndoREZ cone ( UA/EC ) ; and ( 8) UA/TPGDA + ZnO/TPU ( UA/PU ) .  Eighty 1-mm-thick root slices prepared from extracted human permanent molars were r and omly divided into 8 groups with 10 specimens in each group . Root slices were filled with the above obturation material s , and then push-out test was performed with a universal testing machine . The results showed that the UA/EC and UA/PU groups had significantly higher bond strengths than the other groups
