Objectives: Evaluation of the changes to the initial simulated root canal anatomy when comparing the preparation made by three different rotary systems: ProTaper Universal, ProTaper Next and ProTaper Gold. Methods: The quantitative analysis was made by measuring the canal width of 36 S-shaped canals, distributed by three groups of twelve samples each (Group A - ProTaper Universal, Group B - ProTaper Next, Group C - ProTaper Gold). To measure canal width, pre and post instrumentation images were superimposed and studied using Rhinoceros Software. The statistical analysis was obtained using Kolmogorov-Smirnov test, Mann-Whitney post hoc multiple comparisons U test and One-Way ANOVA, with a significance of p < 0.05. Results: Considering the inner side of both apical and coronal curvatures, differences between files were statistically significant (p < 0.05). ProTaper Universal system was responsible for a bigger widening, while ProTaper Gold presented the smaller mean value. Conclusions: ProTaper Gold was the rotary system that most respected the initial S-shaped canal anatomy. ProTaper Universal was the system that originated the greatest modification of the initial canal, presenting a significant tendency to straighten the apical curvature.
