Aims: The aim of the present study was to compare the effect of saline, ethylenediaminetetraacetic acid (EDTA) 17% solution and EDTA paste on root canal transportation. Subjects and Methods: Moderately curved mesiobuccal roots of 24 maxillary molars were standardized in length and randomized into one control and two experimental groups. All teeth were scanned by cone beam computed tomography (CBCT) to determine the root canal shape and measure the parameters required for comparison before instrumentation. The canals were instrumented with 0.06 taper rotary files to size #25. All groups were irrigated with saline. Group 1 was prepared with RC-Prep (Premier Dental, Philadelphia, PA, USA) and in Group 2, EDTA 17% solution (Pulpdent Corp., Watertown, MA, USA) was used. After preparation, postinstrumentation scan was performed. Pre- and post-instrumentation images were obtained at three levels, 3 mm from the apical end of the root (apical level) and 3 mm below the orifice from the coronal level (15 mm from the apex) and the mid-root level (8 mm from the apex) were compared using CBCT software. The amount of canal transportation was assessed. Statistical Analysis Used: The data were analyzed with one-way analysis of variance (α = 0.05) and the Tukey post hoc test. Results: Less canal transportation was observed in experimental groups than the control group. Group 1 showed significantly less canal transportation than Group 2 and control group. Conclusions: EDTA preparation had a significant effect on canal transportation.
