Different Motions of Rotary Instruments

Abstract

The introduction of rotary instruments has been a major breakthrough in endodontics. This is in part, due to the NiTi composition of these instruments; which allows for successful cleaning and shaping of the root canal. The success of these instruments is primarily achieved through the different motions of the rotary instruments. These motions include the rotary and reciprocating technique which allows for lowered fatigue resistance, lowered compressive and tensile stress; improving the predictability and effectiveness of endodontic treatment
