Cutting efficiency of ProDesign R, Reciproc Blue and WaveOne Gold reciprocating instruments

This study aimed to evaluate, in vitro, the cutting efficiency and time spent for instrumentation of three different heat-treated reciprocating systems simulated straight canals. Forty-five acrylic blocks with a root canal 21 millimeters length were initially weighed (P1). After weighing divided into groups (n = 15) each group prepared following systems: ProDesign R 25.06 (Bassi/Easy, Belo Horizonte, Brazil), Reciproc Blue25.08 (VDW, Munich, Germany) Wave one Gold (Dentsply Sirona, Ballaigues, Switzerland). The total preparation block was recorded. instrumentation, they subjected final (P2). difference between P1 P2 determined amount material removed (cutting efficiency) by mechanized system. statistical analysis performed ANOVA test variables, multiple comparisons means turkey used. As time, it can be seen that showed longer (P <0.5) compared Blue Gold. Regarding efficiency, there no (P> 0.5). In canals, type instrument influences instrumentation; however, shows similar efficiency.
