摘要: Purpose: The aim of this in vitro study was to compare the interface dentin-sealer two sealers (RealSeal and AH Plus) using magnifications under Scanning Electron Microscope (SEM). Methods: coronal thirds eight extracted molars were removed dentin surfaces grounded with sequential use #180 #320 SIC paper water cooling. samples divided into groups four accordance sealer be used. treated 17% EDTA followed by 5.25% NaOCl. Cylinders from polyethylene tubes applied filled freshly prepared sealers. Following 2h setting storage at 37oC 100% humidity for a week, teeth cut perpendicularly allow visualization area containing hole, thus dentin-sealer. SEM analysis done three areas along interface, 150x and1000x. Results: repeated measures ANOVA showed no significant differences between magnifications. AH-Plus displayed significantly more gaps than RealSeal. (p=0.002). increase magnification, 1000x, did not any additional identification gaps. Conclusion: RealSeal produced less Plus. It could assumed that is good enough show defects
