Abstract

Aim: This ex vivo study compared the shaping characteristics of Edge Endo, Mani Silk, Hyflex EDM, and FKG 3D Shaper file systems using cone-beam computed tomography (CBCT). Methodology: Eighty extracted human permanent mandibular first molars with mesial roots curvature angles ranging within 20–30° were assigned into four groups (n = 20 each). Teeth were imaged (90 micron resolution) with CBCT
imaging software CS9300 equipment set at 84Kv, 5mA, 10.8 s exposure, and a slice thickness of 76 um to obtain a pretreatment outline of the root canals. All the scans were reoriented with respect to x, y, and z axis. The canal transportation and volume of root canals were evaluated at 1.0, 2.0, 3.0, 4.0, and 5.0 mm intervals. Results: Hyflex EDM Files did the least modifications in canal anatomy as compared to other groups
(P < 0.05). Conclusion: Hyflex EDM maintained the original canal anatomy.
