Purpose: The present study investigated the shaping ability of the WaveOne Gold (WOG) in torque generation with and without establishing different glide paths.
Materials and Methods: Endo-training resin, blocks were divided into three groups: two glide-path groups (ProGlider (PG), WaveOne Gold Glider (WGG)), and a no-glide-path group. Each group was subdivided into two subgroups for the shaping instrument WOG and the ProTaper Next (PTN) as the control. The shaping time and torque generation were calculated, and the canal centering ability was compared between the different glide paths and the no-glide-path group.
Results: The shaping time and total generated torque for the WOG were significantly reduced by a glide path (p<0.05). The WOG generated a higher maximum torque than the PTN regardless of the glide path (p<0.05). The canal centering ratio of the WOG for both glide paths was significantly lower than that for the no-glide-path group, although that of the PTN for both glide paths was not different.
Conclusions: The establishment of a glide path (PG, WGG) and the mechanical properties of the WOG significantly affect the shaping time, torque generation and canal centering ability.
