Miscellaneous endodontic instruments. From left: Lentulo spiral, reamer, K-file and H-file. Hand files can provide tactile sensation when cleaning or shaping root canals. This allows the dentist to feel changes in resistance or angulation, which can help determine curvature, calcification and/or changes in anatomy, in which two dimensional radiographs may not always identif
As the speed of a handpiece increases, its torque subsequently decreases (slow-speed handpieces have high torque, whereas high-speed handpieces, like the air turbine system, have a low torque) The free running speed of 1:5 gear ratio electric handpiece is the same as its cutting speed; thus, 40,000 motor speed x 5 = 200,000 rpm burr speed.
Root canal procedure: unhealthy or injured tooth, subsequent creation of an access cavity with a dental handpiece, cleaning and shaping the root canals with an endodontic file, and restoration with gutta-percha filling and a crown Removing infected pulp during a root canal procedure
