Resumen:
Background: The aim of this study was to analyze the e ects of the time of use (TU)
and sterilization cycles (SC) of endodontic reciprocating files on cyclic fatigue resistance. Methods:
One-hundred-and-twenty (120) Procodile NiTi endodontic reciprocating instruments were selected
at random and distributed into the following study groups: A: 0 sterilization cycles/0s time of use
(n = 10); B: 0/60 (n = 10); C: 0/120 (n = 10); D: 1/0 (n = 10); E: 1/60 (n = 10); F: 1/120 (n = 10); G: 5/0 (n = 10);
H: 5/60 (n = 10); I: 5/120 (n = 10); J: 10/0 (n = 10); K: 10/60 (n = 10); and L: 10/120 (n = 10). A dynamic
cyclic fatigue device was designed using computer-aided design/computer-aided engineering
(CAD/CAE) technology and created with a 3D printer to simulate the pecking motion performed
by the clinician. Failure of the endodontic rotary instrument was detected by a light-emitting
diode-light-dependent resistor (LED-LDR) system controlled by an Arduino driver complex and
management software. The results were analyzed using the ANOVA test. Results: All pairwise
comparisons presented statistically significant di erences between the time to failure, number of
cycles to failure and number of cycles of in-and-out movement for the time of use study groups
(p < 0.001), but not in the number of sterilization cycles (p > 0.05). Conclusions: The time of use of
NiTi endodontic reciprocating files negatively a ects dynamic cyclic fatigue resistance. Dynamic
cyclic resistance is not a ected by the number of sterilization cycles.
