Introduction: This study assessed the influence of voxel size and filter application in detecting second mesiobuccal canals (MB2) in cone-beam computed tomography (CBCT) images.
Methods: Using the OP300 CBCT system and three voxel size protocols - 80 μm, 125 μm, and 200 μm -, we scanned 40 first molars: 20 with MB2 canal and 20 without. All molars received silver-palladium pins on the palatal root, while the non-MB2 were also filled with gutta-percha. Read More
