Means with the same letter are not significantly different from each other; lowercase letters indicate significant differences between groups (P < 0.05); uppercase letters indicate significant differences among systems (P < 0.05) A* = Gutta-percha/Sealer; B* = GuttaFlow; T1 = time to reach WL; T2 = time for complete removal of filling material.
