Assessment of Different Removal Techniques for Bioceramic-based Root Filling Material in Long Oval Canals of Mandibular Premolars: A Micro-Computed Tomographic Study
This micro-CT study of mandibular premolars with long oval canals found that no single retreatment technique using ProTaper Universal, solvents, or specific tips was superior in removing bioceramic-based iRoot SP sealer and gutta-perpa, with the apical third retaining the most residual material regardless of the method used.
