They found that WaveOne Gold had significantly reduced torque created if an Endo glide path had been established the older version generated a higher maximum torque than did WaveOne Gold regardless of the establishment of a glide path (Tables 1 and 2, see below). The blocks were instrumented with the files while the authors carefully monitored the torque applied to each file. To compare the newer file design and heat-treated alloy, the authors measured 2 types of WaveOne files (Dentsply/Maillefer): the older version WaveOne and the newer version, WaveOne Gold (Figure 1). An additional 15 blocks did not have glide paths. Kwak et al from Pusan National University, South Korea, investigated the effect of glide paths on new reciprocating NiTi files by establishing glide paths in 15 resin endodontic training blocks using rotating files specifically designed to create such a path (ProGlider, Dentsply/Maillefer Figure 1, see above). ![]() It is not clear, however, whether the new and improved NiTi files, particularly those that reciprocate within the canals rather than rotate 360°, need a glide path prepared as do the older NiTi files. Creating a glide path of sufficient size before introducing the initial rotary NiTi file into the canal has been shown to significantly reduce the risk of file breakage. Over the years, research has discovered that one way to reduce the risk of torsional failure is to establish am Endo “glide path” down to the apical area of the tooth prior to using the motor-driven shaping NiTi files. These improvements, however, have come at some cost to the torsional strength. Many manufacturers of NiTi files have, with some success, actively developed new file designs and heat treatments of the NiTi alloy to improve cyclic fatigue and flexibility of the NiTi files, thereby reducing the risk of file breakage when they are used inside the canals. If the torque control of the motor does not sense this, the file will break, leaving the tip firmly engaged inside the canal. Torsional failure occurs when the tip of the file engages inside the canal such that it does not rotate anymore, but the motor continues to rotate the rest of the file.Cyclic fatigue occurs when the file has been bent too many times repeated tension and compression stresses cause fatigue crack propagation, and the file simply breaks.NiTi files principally break for 2 reasons: The likelihood of a successful therapy can thereby be greatly diminished. If a file breaks inside a canal, it is usually very difficult, if not impossible, to retrieve it, and it is not possible to further instrument and irrigate beyond it. However, they do come with one important disadvantage: a higher risk of file separation or breakage compared with stainless steel hand files.

The E-COM Cordless Endodontic Motor made by woodpecker is one of the best priced endo motors in the market with features that eclipse its more expensive rivals.The E-COM can be used for both standard rotary and reciprocating systems however what sets it apart from most is that it comes with all leading file systems pre set into its memory. WaveOne Gold brings to the endodontic procedure a metallurgically advanced single-le technique for shaping canals. WAVEONE® GOLD is the latest generation of reciprocating file technology developed by DENTSPLY MAILLEFER in collaboration with four endodontic key opinion leaders (Drs. Endodontic Rotary / Reciprocating Files.
