Push-out bond strength is affected by irrigation techniques and sealers in root canals, suggesting optimization is needed for better adhesion.
Both the irrigation activation technique and the choice of calcium silicate-based sealer significantly influence push-out bond strength, predominantly in the coronal region. Sonic activation with EDDY in combination with BioRoot RCS yields the most favorable bonding performance. The diminishing effect toward the apical region underscores the need for further optimization of activation strategies to enhance sealer-dentin adhesion throughout the entire root canal system.
