Eighty-four single-rooted teeth were instrumented until the F4 ProTaper universal rotary file and filled with AH26, AH Plus (Dentsply, DeTrey, Konstanz, Germany), RealSeal (SybronEndo, Orange, CA), and MTA Fillapex (Angelus, Londrina, Brazil) using cold lateral condensation (CLC) and single-cone (SC) obturation techniques. Thereafter, the roots were sectioned longitudinal and prepared for scanning electron microscope evaluation. The maximum and minimum sealers penetration depth into dentinal tubules at the apical, middle, and coronal regions and the average depth of sealer penetration were calculated. The data was statistically analyzed two-way ANOVA and post hoc Tukey and Dunnett tests and independent samplesttest using maximum mean values. There was no statistically difference between the obturation methods (p> .05). When the sealers are evaluated within themselves AH26 was affected by obturation methods significantly (p< .05). Also the results revealed a significant difference between root regions (p< .05). AH26 and RealSeal root canal sealers had the highest penetration values with CLC and SC obturation techniques, respectively. The obturation method did not affect the penetration amount of root canal sealers. RealSeal root canal sealer performed better penetration ability than the other sealers. Apical third of the root in all groups showed lowest penetration depth.eninfo:eu-repo/semantics/closedAccessMTA Fillapexroot canal sealersealer penetrationsingle-cone techniqueArticle83121544155110.1002/jemt.235482-s2.0-8508880894632735400Q1WOS:000553969300001Q1
