Scanning Electron Microscopic Evaluation of the Sealer-Dentine Interface of Three Sealers.

INTRODUCTION: This study aimed to evaluate the dentine-sealer interface in three different sealers using scanning electron microscopy (SEM). METHODS AND MATERIALS: C. Cross sections were prepared from the coronal, middle, and apical sections of the roots. Then SEM images were taken and the width of gaps was measured by software. Sectional images were evaluated by two endodontists. Data were analyzed using two- and one-way ANOVA and Kruskal-Wallis tests. RESULTS: =0.001). CONCLUSION: BC Sealer and AH-Plus had less gaps than Dorifill in coronal area. In addition, BC Sealer had better dentine interface in middle and coronal area compared to AH-Plus, and both performed better than Dorifill. Reverse relationship was observed between the mean gap width and dentine-sealer interface quality.
