Abstract/Artist Statement

Nickel-Titanium (NiTi) files are widely used during endodontic root canal procedures. NiTi files possess unique properties that increase the difficulty of visually determining the futigue and consequently the failure of the files by the dentist during the root canal procedure. Our BENG 195 Senior Design project, performed under the sponsorship of the American Dental Association 1 , seeks to improve upon existing methods for testing rotary NiTi endodontic files. An Endodontic File Fatigue Tester (EFFT) was designed to allow for the continuous filing of an Artificial Dental Canal (ADC) until breakage occurred. The EFFT provides for precision testing of the files over a range of angles (30', 45', and 60') while being bent to various radii of curvature (2mm and 5mm). The ADC's were composed of Aluminum Alloy 6061 and Copper Alloy 101. Preliminary observations suggest that the lifetime of endofiles decreases as the angle and radii of curvature increases. 1 S.J.
