Abstract
Abstract
Introduction: File separation within the root canal during canal preparation is a significant concern for dentists. Systems like ProTaper Gold, Pronix Gold, and Pronix Blue are relatively new systems that have been developed by improving NiTi alloys through heat treatment. The aim of this study is to determine the cyclic fatigue resistance of Pronix Blue, Pronix Gold, and ProTaper Gold files.
Methods: In this experimental laboratory study, conducted in the 2023 in the Isfahan Dental Research Center ,45 rotary files of Pronix Blue, Pronix Gold, and ProTaper Gold size F2 in3 group was used .All files were inserted and removed from the canal until fracture, using the same torque and speed. Statistical analysis was performed using SPSS software version 26, with a 5% error level using one-way ANOVA test and Tukey HSD to examine pairwise differences between groups.
Results The mean number of cycles to failure (NCF) was 165.40 for the ProTaper Gold group, 178.60 for the Pronix Blue group, and 141.20 for the Pronix Gold group. Tukey's test revealed significant differences in the mean number of cycles to failure between the Pronix Gold and Pronix Blue files and ProTaper Gold (P<0.001).
Conclusion The results of this study indicated that the lowest failure resistance was observed in the Pronix Gold rotary file group, while the highest failure resistance was found in the Pronix Blue group.
