Effect of Different Chemo-Mechanical Shaping Protocols on the Intratubular Penetration of a Bioceramic Sealer.

ABSTRACT: Background: This study aimed to evaluate the effect of two shaping systems combined with different irrigant activation methods on the tridimensional distribution of a bioceramic root canal sealer. Methods: Sixty single, round, straight root canals from extracted human teeth were randomized into six groups (n = 10): A1-A3 shaped with RACE NiTi rotary files; B1-B3 shaped with an adaptive XP-Endo Shaper. NaOCl and EDTA irrigation was performed using passive ultrasonic irrigation (PUI, group 1), conventional endodontic needle irrigation (CENI, group 2), or XP-Endo Finisher mechanical activation (group 3). Canals were obturated using the single-cone cold gutta-percha technique with BioRoot RCS bioceramic sealer. Confocal laser scanning microscopy was used to assess sealer p
