%X For accomplishment of this study, three automated pieces were selected: M4 (Kerr Corporation), Endo-Gripper (Moyco Union Broach) and NSK TEP-E10R (Adiel Super Endo), all with nearly one year of use. Tests were performed at speeds of 6000, 8000 and 10000 rpm, with observation of their influence on the angular pathway of the systems. Recording of the tracing of angles was achieved by integration of an apparatus comprising endodontic fi le, plastic rod and graphite, connected to the automated handpiece, so as the end of the graphite was in contact with a millimeter paper. After statistical analysis, the results achieved revealed that none of the automated pathway indicated by the manufacturer, i.e 45o for Endo-Gripper an NSK, and 30o for M4, having a total pathway of 90o and 60o, respectively; moreover, the pathway of oscillating movements was related to the system and speed employed.
