“…Many studies have tested CF in metal devices with different designs including constricting the file into a curvature delimited by stainless steel pins (31,32) or using different types of simulated canals (10,14,24,33,34). The device used in this study allowed for the selection of the exact point at which CF resistance was to be tested (5 mm).…”

“…The thermal treatment of NiTi (9,13,14), cross-section of files (15,16), speed in continuous rotation (17,18), and manufacturing methods (5,9,19,20) are parameters that are known to influence the CF resistance of files. Testing the CF resistance of these 3 different systems allows for analysis of the relative importance of these parameters that supposedly influence the behavior of NiTi rotary files in clinical situations because each of these systems has characteristics that make it different from the others but, at the same time, somewhat comparable.…”

“…[11,16] In many reports, a simulated canal in a steel block was used to evaluate the cyclic fatigue of NiTi instruments. [17][18][19] Similarly, in the present study a simulated canal in a steel block was used for the cyclic fatigue testing. Plotino, Grande [20] reported that the convex cylinder contacts the tapered instrument in a nonpredictable way so that the instrument may fit loosely and radius and angle of curvature may not be repeatable .…”

“…On the other hand, some studies [35][36][37] proposed that the cross-sectional design was a significant determinant. In a supplementary examination using SEM, the cross-section of each instrument was captured at 5 mm away from the tip, and the area was measured using ImageJ software (http://rsbweb.nih.gov/ij).…”
