Fig. 4From: The remaining dentin thickness investigation of the attempt to remove broken instrument from mesiobuccal canals of maxillary first molars with virtual simulation techniqueThe means and standard deviations for RDT by different methods. 3D-RDT(=3D remain dentin thickness), Pa-RDT(= remain dentin thickness obtained from parallel technique), An-RDT(= remain dentin thickness obtained from angulated technique), green and blue color were instrument broken 3 mm and 5 mm below the orifice (group 3 mm and group 5 mm)Back to article page
