Table 1.
Bond strength results (MPa) measured between root canal dentinal walls and root canal filling material, regarding the type of root canal sealer [AH-Plus (AH); EndoSequence BC Sealer (BC)], the final-step irrigation method [syringe-needle irrigation/conventional (IC); passive ultrasonic irrigation (PUI); XP-endo Finisher agitation (XP)], and the root canal thirds (cervical; middle; apical). *Root canal filling material was composed of root canal sealer and gutta-percha
