In vitro Evaluation of Cyclic Fatigue Resistance of Reciprocating and Rotary Single-file System
نویسنده
چکیده
Aim: In vitro study evaluation of the cyclic fatigue resistance of reciprocating and rotary single-file system [Wave One Gold (WOG), Reciproc, Hyflex electrical discharge machining (EDM) file systems] utilizing cyclic fatigue testing device. Materials and methods: Three nickel–titanium rotary systems (Hyflex EDM size #25, 0.06 taper and Reciproc and WOG size #25, 0.06 taper) were used in this study. Ten files were used in each file system, which are 25 mm long and tested with cyclic fatigue and torsional resistance tests. Results: Each file was tested in the simulated root canal until instrument fracture occurred. Hyflex EDM has high mean and standard deviation of 116.23 ± 4.41, followed by WOG (64.85 ± 3.34) and Reciproc (35.28 ± 2.32). Conclusion: Within the limitations of this study, Hyflex EDM exhibited the greater cyclic fatigue resistance when compared with other rotary and reciprocating files.

Comparison of cyclic fatigue and torsional resistance in reciprocating single-file systems and continuous rotary instrumentation systems.
As compared with continuous rotary systems, reciprocating motion is believed to increase the fatigue resistance of NiTi instruments. We compared the cyclic fatigue and torsional resistance of reciprocating single-file systems and continuous rotary instrumentation systems in simulated root canals. Eighty instruments from the ProTaper Universal, WaveOne, MTwo, and Reciproc systems (n = 20) were s...

Introduction: The purpose of this study was to evaluate surface topography of WaveOne Gold (WOG) and WaveOne (WO) files using SEM before and after use. Methods: Twelve primary files from each system were scanned for surface defects before instrumentation at 100x and 750x. Each file was planned ti be used to instrument six root canals and then examined under SEM after preparing one, three and six...
