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 ) .
Effect of irrigation technique for removal of triple antibiotic paste on bond strength of MTA to root dentin.
This study evaluated the bond strength of mineral trioxide aggregate ( MTA ) to root canal dentin after the performance of various irrigation procedures to remove triple antibiotic paste ( TAP ) . A total of 56 single-rooted human m and ibular premolars were instrumented using a rotary system to size 40 and divided r and omly into a control group ( no intracanal dressing ) and three experimental groups ( TAP application for 28 days ) . TAP was then removed by rinsing with 10 mL 2.5 % NaOCl using three irrigation systems ( Vibringe sonic irrigation , CanalBrush , and syringe irrigation ) . The coronal and middle parts of root canals were then obturated with MTA . After storage for 1 week , each specimen was embedded in an acrylic block and sectioned horizontally ( 2-mm-thick slices ) at two levels ( coronal and middle ) . Bond strength of MTA to root canal dentin was assessed in 28 sample s per group via push-out test using a universal testing machine . Data from the four groups were compared using one-way analysis of variance . Tukey 's test was used for multiple comparisons . Push-out bond strength values were significantly higher in the control and Vibringe groups than in the CanalBrush and syringe irrigation groups ( p < 0.001 ) . TAP removal from root canals with the Vibringe irrigation system may increase the push-out bond strength of MTA compared with the use of the CanalBrush or syringe irrigation
