Comparison of shaping ability of ProTaper Next and 2Shape nickel–titanium files in simulated severe curved canals. Analisi sperimentale della preparazione endodontica in canali artificiali con curvature complesse: ProTaper Next Vs. 2Shape
Aim
To evaluate the centering ability of ProTaper Next (PTN) and 2Shape (TS) nickel–titanium (NiTi) instruments in terms of maintaining the original root canal configuration in a simulated tooth with severe curvature.
