Improved Root Canal Instrumentation to Reduce Dental Work Complications

Doctors suggest that the " adaptive " motion of nickel-titanium rotary files used for root canal procedures decreases the instrument ' s torque generation, thereby reducing the risk of tooth damage and file fracture YANGSAN, South Korea, Oct. 7, 2019 /PRNewswire/ -- Reducing dental work complications is in best interest of dentists as well as patients. To improve clinical performance of root canal instruments, a research team, led by Dr. Sang Won Kwak from Pusan National University, South Korea, tested instrumentation with specially designed rotary movements. Their study, published in Journal of Endodontics, suggests that adaptive movement of nickel-titanium (NiTi) files improves the success rate of root canal treatment by lowering the torque generation of the instruments. A lower torque will help reduce the risk of tooth damage and file fracture.As shown in this infographic, adaptive movement of the NiTi files was better than continuous rotary movement; this was reflected in lower total torque (Ncm) and shorter preparation times (seconds)Over the years, root canal dental work has been improved with the use of engine-driven NiTi files. Compared with stainless-steel manual files, NiTi instruments offer better flexibility and cutting efficiency, in addition to reduced iatrogenic errors. However, the NiTi files may have cyclic fatigue and torsional failure problems during the root canal procedure. To reduce the risk of file fracture, ...
