Abstract

The objectives of the present work are to discuss the role of engineering in developing the instruments applied in root canal therapy. The development includes enhancing the flexibility and elasticity of the materials of files to withstand the stresses that they are subjected to. Based on the research, it was confirmed that the reciprocating motion of files displayed a longer cyclic fatigue life compared to complete rotation. It is proposed to apply single-use files to prevent cross-contamination, where the number of cycles of the files to failure is lower than the limits of cyclic fatigue failure. Besides, the manufacturer of the instruments should supply the users by the specifications of the materials such as the mechanical properties that include tensile and compressive stresses as well as hardness. Finally, further studies are proposed to determine the speed and rotating angles of the reciprocating motions of the endodontic files.
