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 the bond strength of root-end placed mineral trioxide aggregate and Biodentine in the absence/presence of blood contamination
Objective : Mineral trioxide aggregate ( MTA ) has been accepted as an appropriate root-end filling material in endodontic microsurgery because of setting ability in the wet environment . The aim of this study was to assess the bond strength of root-end placed MTA and Biodentine ( Septodont , Saint Maur des Fossés , France ) in the absence/presence of blood contamination . Material s and Methods : Forty-eight single-rooted maxillary incisors were used . subsequent to root-end resection and apical preparation using ultrasonic retro-tips , the specimens were r and omly separated into two groups according to the root-end filling material s : MTA ( Cerkamed Medical Company , Stalowa , Pol and ) or Biodentine . The specimens were then separated into two subgroups according to storage condition ( absence/presence of blood ) ( n = 12 ) . After obtaining 2.0 ± 0.1 mm slices , push-out tests were performed . Each slice was examined under a stereomicroscope to evaluate the failure mode . The data were analyzed using two-way analysis of variance and Tukey 's post hoc test for multiple comparisons . The failure modes were analyzed using the Chi-square test ( P = 0.05 ) . Results : The bond strength was significantly affected by the presence of blood contamination and root-end filling material type ( P < 0.001 ) . Biodentine had better bond strength than MTA ( P < 0.001 ) . The most common failure type was adhesive failure . According to the Chi-square test , there were no statistically significant differences among the groups ( P = 0.394 ) . Conclusions : Biodentine had better bond strength values compared to MTA , and the bond strength of both MTA and Biodentine as root-end filling material s was negatively affected by the presence of blood
