INTRODUCTION: The aim of the study was to evaluate apical transportation of root canals after the use of RaCe (FKG Dentaire, La-Chaux-de-Fonds, Switzerland) and ProFile (Dentsply Tulsa Dental, Tulsa, OK) 40/.04 rotary files. METHODS: A double-digital radiographic technique was used to compare apical transportation between the RaCe and ProFile systems. Mesial canals from 80 extracted mandibular molars were instrumented using each rotary system. The central axes of the file imaged before instrumentation (#15 K-file) and the master apical rotary file (#40/.04) were superimposed digitally. AutoCAD was used to measure apical transportation at 0.5 mm from the working length (1.5 coronal to the major foramen). The data were analyzed using the Student's t test, and significance was set at P < .05. RESULTS: The mean amount of apical transportation at 0.5 mm was 0.17 ± 0.01 mm for the ProFile group and 0.16 ± 0.01 mm for the RaCe group. No statistically significant differences in apical transportation were found between the 2 groups. CONCLUSIONS: Under the conditions of the study, no statistically significant differences in apical transportation were observed between ProFile and RaCe rotary files.
