Root canal preparation is an important process in endodontic therapy. Root canals can be shaped in continuous motion by rotary instruments using a crown-down technique and a single lenght technique (simultaneous technique) as well. Most rotary systems require a crown-down approach to minimize torsional loads and to reduce the risk of instrument fracture. The most known of these are ProTaper Universal and ProTaper Gold (Dentsply Sirona). On the other hand, there are also on the market rotary systems that shape the canal in a single lenght technique. These are ProTaper Next (Dentsply Sirona) and Mtwo (VDW). These instruments are used without early coronal enlargement and are lead up to the working length without apical pressure. This work has the aim to compare the ability of two techniques to prepare uniform tapered the root canals and to maintain the original shape of curved canals during preparation.
