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 ) .
Micro-computed tomography and bond strength analysis of different root canal filling techniques.
INTRODUCTION The aim of this study was to evaluate the quality and bond strength of three root filling techniques ( lateral compaction , continuous wave of condensation and Tagger 's Hybrid technique [ THT ] ) using micro-computed tomography ( CT ) images and push-out tests , respectively . MATERIAL S AND METHODS Thirty m and ibular incisors were prepared using the same protocol and r and omly divided into three groups ( n=10 ) : Lateral condensation technique ( LCT ) , continuous wave of condensation technique ( CWCT ) , and THT . All specimens were filled with Gutta-percha ( GP ) cones and AH Plus sealer . Five specimens of each group were r and omly chosen for micro-CT analysis and all of them were sectioned into 1 mm slices and subjected to push-out tests . RESULTS Micro-CT analysis revealed less empty spaces when GP was heated within the root canals in CWCT and THT when compared to LCT . Push-out tests showed that LCT and THT had a significantly higher displacement resistance ( P<0.05 ) when compared to the CWCT .  Bond strength was lower in apical and middle thirds than in the coronal thirds . CONCLUSIONS It can be concluded that LCT and THT were associated with higher bond strengths to intraradicular dentine than CWCT . However , LCT was associated with more empty voids than the other techniques
