In the tip region, the cross section presented radial lands, while in the middle part and near the shaft, the cross-sectional diameter changed from a modified triangular/convex cross section with radial lands to a neutral rake angle with a triangular/convex cross section (Brklein, et al., 2012). Data were statistically compared using MannWhitney U-test and the independent t-test, with a confidence interval of 95%. It has been suggested, however, that the use of a glide path is beneficial for improving the performance of reciprocating instruments. This will usually include larger diameter, relatively straight root canals. J Endod. 2006;32(1):61-65. The counterclockwise (CCW) movement of 150 degrees is capable of advancing the instrument apically as the dentin on the root canal wall is engaged and cut. Recently, a large variety of nickeltitanium (NiTi) rotary systems with improved cutting efficiency and flexibility have become commercially available. This optimizes efficiency for clinicians and decreases total shaping time by up to 40% versus a traditional continuous-motion rotary technique (data on file, DENTSPLY Tulsa; www.waveonefile.com).

Reciproc and WaveOne reciprocating file systems are made by the same new M-wire NiTi alloy but have different cross sections, S-shape, . The WaveOne Gold primary file (Dentsply Sirona) is 50% more resistant to cyclic fatigue, 80% more flexible, and 23% more efficient than the conventional WaveOne primary instrument (Ruddle, 2016; Webber, 2015). WaveOne Gold large file (white ring) (Figure 5) tip of the file is ISO 45, and the first 3 mm of the file (D1-D3) has a continuous taper of 5%. The tip sizes match ISO standard sizing in 020, 025, 035 and 045 and the smaller maximum fluted diameters help conserve coronal dentin. This movement is followed by a 30-degree clockwise (CW) movement, which ensures that the instrument disengages before excessive torsional stress is transferred onto the metal alloy and before the instrument can bind (taper lock) into the root canal. . So go ahead take on the next root canal case with confidence. What is the difference between WaveOne Gold and ProTaper Gold? In the majority of cases, a single file can be used to complete root canal preparation with adequate resistance form to ensure exchange of irrigation solutions for adequate disinfection prior to root canal obturation in single or multiple root canal systems (Figure 7). Gauging the apical foramen with a corresponding nickel-titanium hand file is another alternative (Ruddle, 2016).
