ARACENA, D.; BUSTOS, L.; ARACENA, A.; ALVAREZ, P. & HERNÁNDEZ-VIGUERAS, S. Apical sealing efficacy of the bioceramic cements Bio Root and MTA Fillapex: an ex vivo study. Int. J. Odontostomat., 15(2):473-478, 2021. ABSTRACT: The aim of this ex vivo study was to compare the ability of the apical sealing bioceramic cements BioRoot™ RCS (Septodont) and MTA-Fillapex (Angelus). One hundred and eighty-four vestibular canals were selected from ninety-two recently extracted maxillary molars. Canals were instrumented with the mechanized system ProTaper Next and obturated using the single cone technique. The sample was randomly divided into two groups (92): Group 1 was obturated with BioRoot ™ RCS, and Group 2 with MTA-Fillapex. Samples were processed for the leakage test by dye penetration and later cut longitudinally. The data obtained were tabulated and analyzed using Stata 15.0. The degree of leakage from BioRoot ™ RCS was 0.03 mm, and MTA-Fillapex was 0.31 mm p (0.00). BioRoot ™ bioceramic presented an adequate apical sealing, while MTA-Fillapex showed an accentuated leakage.
