Assessment of cyclic fatigue resistance of Ni-Ti reciprocating rotary files- Wave One Gold and Reciproc- An in-vitro study
Narendeep Ashutosh, Sanjeev Chauhan

Background: Reciproc and Wave One Gold are a new generation single-file systems that have recently been introduced and used in the market. Both file systems have reciprocating motion. This study assessed the cyclic fatigue resistance of two different Ni-Ti reciprocating rotary files Wave One Gold and Reciproc. Materials & Methods: This in-vitro study was conducted in the department of Endodontics. Group I comprised of wave one gold files size 25 taper 0.07, and group II had reciproc files size 25 taper 0.04. Each file rotated continuously with 350 rpm speed and 2.5Ncm torque until the file was fractured. The time elapsed during rotation until fracture was recorded. Results: Group I comprised of wave one gold files and group II had reciproc files. The time required fracturing file system in group I was 10.5 seconds and in group II was 9.4 seconds. The difference was non- significant (P> 0.05). Conclusion: Authors found no difference in time requiring in achieving fracture of their file system in both groups. Key words: Fatigue resistance, Reciproc files, Wave one
