The aim of this study was to compare, by micro‐computed tomography (micro‐CT) analysis, the obturation quality of two filling methods: the single‐cone technique with the bioceramic EndoSequence BC sealer and the continuous wave technique with the resin‐based AH Plus sealer. Twenty mandibular molars were divided into two groups (n = 10) according to the sealer used. Only the mesial roots, which are known to have mostly two canals, were used. The specimens were scanned before and after instrumentation and after obturation. Root canal volume after instrumentation and filling volume were calculated to obtain the percentage volumes of filling, voids and gaps. All specimens presented final volumes that were smaller than the initial volumes (P < 0.05). There was no significant difference between groups for filling volume, voids and gaps (P > 0.05). Using two filling methods, EndoSequence BC and AH Plus promoted a similar root filling quality in mesial roots of mandibular molars. Neither sealer was able to fill the root canal system completely.
