The mesio-lingual and mesio-buccal canals were randomly assigned (<em>n</em> = 12) to ProTaper Gold (PG), ProTaper Next (PTN), ProTaper Ultimate (PTU), and B4U instrumentation systems. Pre- and post-shaping micro-CT scans were performed to compare root canal volume and cervical dentin volume. The centroid shift and the percentage and distribution of the dentin removal in correspondence of the mesial canals were analyzed in coronal, middle, and apical points of analysis and below the furcation at the “danger zone.” The residual dentin thickness in the distal and mesial aspects of the mesial canals was measured. A linear elastic model of a mesial root of a mandibular molar was created through the finite element method (FEM) and a 200N perpendicular load was applied on the root canal coronal third.
