| Abstract | ||
| This research aimed to evaluate and contrast the cycle fatigue resistance of protaper universal, V-taper gold, and AF Blue R3 endodontic files in an S-shaped canal. In this study, cyclic fatigue assessment, thirty NiTi files were used (n=10) for each group ( A, B, C), group A; ProTaper Universal files, group B; V-Taper gold \ and group C; AF Blue R3. The files undergo testing in double curvature custom-made artificial canals; the Time taken for the file fragmentation and length of the broken fragment were measured, and the fatigue duration of each file was determined. After that, a statistical analysis was conducted on the data using ANOVA, and a post hoc Tukey's test was performed. The NCF of AF Blue R3 files (753.59±109.09) was statistically significantly higher than V-taper Gold and pro-taper universal (p<0.001). At the same time, the NCF of V-taper gold (427.52±44.80) was greater than protaper universal (252.90±50.00) (p<0.001). | ||
