摘要：

A laboratory study was performed on machine-driven Canal Master drills to determine their physical dimensions, torsional performance, bending properties, and metallurgical characteristics in fracture, Physical dimensions were determined for each of the available sizes (#50 to #100) of Canal Master drills from the manufacturer that distributes these instruments in the United States, Samples were also tested in clockwise torsion using a Maillefer memocouple, Bending properties of cantilever specimens were measured with a Tinius Olsen stiffness tester, Bending fatigue testing was performed on a unique laboratory apparatus, Scanning electron microscope examination confirmed visual observations that the stainless steel Canal Master drills exhibited ductile torsional fracture, This study is part of a continuing investigation to establish standards for all machine-driven rotary endodontic instruments.
