Introduction: The ideal endodontic root canal filling should be a compact, homogeneous mass, with adequate adaptation to the canal walls, without voids or irregularities. The aim of the present study was to evaluate the voids of root canals filling of mandibular premolars obturated with two bioceramic sealers (BioRoot RCS and CeraSeal) compared with a resin-based sealer (AH-Plus), with a single gutta-percha cone technique.Methods: Thirty mandibular permanent premolars with a single root canal were selected. The root canals were instrumented with WaveOne Gold system (Dentsply Sirona Endodontics) and irrigated with sodium hypochlorite. The root canal filling was performed with the single-cone technique and the specimens were assigned to three groups (n=10) according to the root canal sealer used: AH Plus Group (AH; Dentsply DeTrey, Germany), BioRoot RCS Group (BR; Septodont, France) and CeraSeal Group (CS; Meta Biomed, Korea). The access cavity of each tooth was sealed with a temporary light-curing Clip plastic resin (Voco GmbH, Cuxhaven, Germany) and the teeth were kept at 37ºC ± 1ºC., with a relative humidity not less than 95% required by IRAM standards, for a period of 180 days. Micro-computed tomographic (micro-CT) imaging was used to scan each specimen and three-dimensional reconstruction was performed using Mimics Innovation Suite V.6. One factor analysis of variance was used with normal distribution data and generalized lineal model for variables with Poisson distribution. Data were analyzed using InfoStat Software (FCA-UNC, Córdoba, Argentina) with statistical significance preset at 5%. Results: In the micro-CT assessment, the mean percentages of volume voids were 0.72% in the Ceraseal group, 1.03% in the BioRoot group and 3.56% in AH Plus group. The difference was statistically significant between the bioceramic sealers and AH Plus (p < 0.05).Conclusions: Most of teeth showed voids in the root canal obturation regardless the root canal sealer used. The Ceraseal bioceramic sealer showed the lower percentage volume and the number of voids than BioRoot RCS and AH Plus in mandibular premolars obturated with a single gutta-percha cone technique.
