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 ) .
Effects of various mixing techniques on push-out bond strengths of white mineral trioxide aggregate.
INTRODUCTION The aim of this study was to evaluate the effect of 3 different mixing methods on push-out bond strength of white tooth-colored mineral trioxide aggregate ( MTA ) . METHODS Sixty 2-mm-thick root sections were prepared from 60 single-rooted human teeth and filled with MTA . The sample s were r and omly divided into 3 groups ( n = 20 ) of MTA mixed by ultrasonic , trituration , or conventional methods and then allowed to set for 72 hours in a synthetic tissue fluid environment . Push-out bond strength values of the specimens were measured by a universal testing machine and examined under a stereomicroscope at × 4 to determine the nature of the bond failure . RESULTS The means of push-out bond strength values of white MTA in the ultrasonic , conventional , and trituration groups were 105.67 ± 12.79 , 118.95 ± 12.76 , and 99.60 ± 14.27 MPa , respectively . The differences between the 3 groups were not statistically significant . CONCLUSIONS On the basis of the results of this study , it can be concluded that different mixing methods have no significant effect on push-out bond strength of white MTA
