dc.descriptionPurpose: To analyze the influence of the pecking motion frequency on the cyclic fatigue resistance of endodontic rotary files. Material and Methods: Sixty PlexV 25.06 endodontic rotary files were selected and distributed into three groups: 30 movements/min (n = 20), 60 movements/min (n = 20), and 120 movements/min (n = 20). A dynamic cyclic fatigue device was designed using Computer Aided Design/ Computer Aided Engineering (CAD/CAE) technology and manufactured by 3D impressions to simulate the pecking motion performed by an operator. Failures of the endodontic rotary files were detected by a Light-Emitting Diode (LED)/Light-Dependent Resistor (LDR) system controlled by an Arduino-Driver complex and management software. Endodontic rotary files were tested on an artificial root canal manufactured by wire electrical discharge machining (EDM),withsimilar dimensionstothoseoftheinstrumentunderexamination. Endodonticrotaryfiles were used following the manufacturer¿s recommendations. The results were analyzed by ANOVA and Weibull statistics. Results: All pairwise comparisons revealed statistically significant di erences in all three variables, except for the di erence in the number of cycles between the groups with 60 and 120 movements/min (p = 0.298). The scale distribution parameter of Weibull statistics showed statistically significant di erences in all three variables, except for the di erences in the number of cycles between groups with 30 and 60 movements/min (p = 0.0722). No statistically significant di erences in the three variables were observed for the shape distribution parameter. Conclusion: Alowfrequency of pecking motion is recommended to reduce the risk of failure of endodontic rotary f iles associated with cyclic fatigue.es_ES
