Aim: This research investigated the transportation and centering ability of Race Evo (RE), Edge File X7 (EX7), Fanta AF F-one, and 2Shape (2S) file systems in artificial curved canals at various levels. Methods: Forty-eight simulated root canals divided into four groups of 12 specimens were tested. Each NiTi-prepared group: RE, EX7, Fanta AF F-one, and 2S system used for consistently preparing the canals, the blocks were photographed, then using Photoshop, before and after images of the preparation were superimposed. The measurement was done at five levels (level 1 was assessed at 5 mm from the orifice, level 2 at 7 mm from the orifice, level 3 at the curve’s beginning, level 4 at its highest point of curvature, and Level 5 at 1 mm from the apex). The Image Analysis Software (Digimizer) and SPSS 21 were used for statistical analysis. P ≤≤ 0.05 was chosen as the statistical significance level. Results: Regarding the levels at which canal transportation and centering ratio were measured a statistically significant difference (P < 0.05) was observed, with the exception of level 1. The Fanta AF F-one system demonstrated the highest values of canal transportation and centering ratio at Levels 3 and 4. Whereas the 2S system exhibited the highest value at Levels 2 and 5. In contrast, the RE system recorded the lowest value at Levels 4 and 5, while the EX7 system had the lowest value at Levels 2 and 3. Conclusion: All file systems result in some degree of canal transportation and do not provide perfectly centered preparation. However, canal transportation was within acceptable ranges in the apical part of all tested groups. In the central and apical regions of the canal, the RE and EX7 systems outperformed the Fanta AF F-One and 2S systems in terms of preserving canal curvature.
