Schematic representation of the four curved artificial canals with different angles and radii of curvature used in the torsional tests, which allowed instruments to remain flexed during test procedures. (A) SS canal with the radius of curvature of 5 mm and the degrees of curvature of 90°; (B) SS canal with the radius of curvature of 3 mm and the degrees of curvature of 90°; (C) SS canal with the radius of curvature of 5 mm and degrees of curvature of 60°; (D) SS canal with the radius of curvature of 3 mm and the degrees of curvature of 60°.
