INTRODUCTION:the objective of this in vitro study was to compare the degree of transportation of root canals using three rotary systems: HERO Shaper, ProTaper Universal, and Race. METHODS:a sample of thirty buccal root canals of upper molars with curvatures between 25 and 35° was divided into three random groups of ten canals each, which were then instrumented by using the rotary systems HERO Shaper, ProTaper Universal, and Race respectively, all to a diameter # 30 to the working length, using the motor NSK Endo-Mate TC to control torque and speed. Radiographs were taken before and after mechanical instrumentation, and they were scanned with DuoScan Agfa T1200 scanner at a resolution of 2400 dpi gray scale. Afterwards, by the method of lineal morphometry and using the computer system for digital images NIH imageJ, a total of 12 measurements per root canal were done: 4 for the total root width, 4 for the concave wall and 4 for the convex wall, all at 1, 2, 4 and 6 mm respectively from the radiographic apex of the canal. The data were analyzed by using the Mann Whitney Rank Sum and Kruskal Wallis nonparametric statistical analysis for independent samples. RESULTS:Transportation was observed from the root canal to the concave wall when the ProTaper Universal system was used, being statistically significant (p = 0,01). CONCLUSION:the ProTaper Universal rotary system produced the greatest number of transportations when compared with HERO Shaper and RaCe systems.
