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 ) .
Evaluation of push-out bond strength of a new MTA-based sealer
Aim To evaluate the push-out bond strength of  MTA Fillapex ( Angelus ) and compare it with ProRoot MTA ( Dentsply ) and AH Plus ( Dentsply ) . Design Thirty extracted single-rooted teeth were selected and prepared using a rotary system . The sample s were divided r and omly into three groups ( n = 10 ) and obturated , respectively , with : ( 1 ) AH Plus + gutta-percha ( DiaDent ) ; ( 2 ) MTA Fillapex + gutta-percha ; ( 3 ) ProRoot MTA . Each root was sectioned into 1-mm-thick slices and 30 sample s for each group were obtained . The sample s were subjected to push-out test . Failure modes were examined under 30 × magnification . The results were analysed statistically by one-way ANOVA and Tukey ’s test . Results Mean push-out bond strength values were ranked as follows : ProRoot MTA > AH Plus > MTA Fillapex . Statistically significant differences were found among all groups ( p < 0.05 ) . Conclusion ProRoot MTA had the highest bond strength , whilst MTA Fillapex displayed the lowest values among the groups
