Abstract
The surface condition of four Ni-Ti rotary file systems after using them to shape premolar root canals ten times are of interest. Laboratory tests through SEM showed substantial surface deterioration because pitting dramatically increased after ten procedures (p < 0.001). The Twisted File system remained in the best condition with the minimum amount of surface damage and second place went to ProTaper Next and V Taper 2H ranked after them and Mtwo showed the maximum wear. The surface wear observed in Mtwo exceeded that of all the other tested Ni–Ti rotary file systems. The assessment of file surfaces aids in minimizing clinical failures of instruments.
