The 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)
