The aim of this study was to assess by confocal laser microscope the depth of dentinal tubule penetration of two tricalcium silicate‐based sealers promoted by two obturation techniques in curved canals compared with AHPlus. One hundred and twenty canals were divided into six groups (n = 20): BCSC‐Bio‐C Sealer (BC) and single‐cone technique (SC); BCCW‐BC and continuous condensation wave (CW); TFSC‐Total Fill (TF) and SC; TFCW‐TF and CW; AHSC‐AH Plus (AH) and SC; AHCW‐AH and CW. Data were analysed using the three‐way ANOVA and Tukey's test (α = 5%). Penetration depth was significantly greater for TFCW than TFSC and greater for AHCW than AHSC (p < 0.05). There was no significant difference between BCCW and BCSC (p > 0.05). The penetration of TF was significantly greater (p < 0.05). The CW technique promoted greater intratubular penetration, except for the BC sealer.
