Objective: This study sought to assess the influence of cervical preflaring and reuse after resterilization, on fracture strength and plastic deformation and/or surface cracking in reciprocating nickel-titanium [NiTi] endodontic instruments after root canal instrumentation of extracted human teeth.
Materials And Methods: Forty engine-driven reciprocating NiTi instruments (20 Reciproc [RC], VDW; 20 WaveOne [WO], Dentsply) were used in root canal instrumentation of extracted human molars. A total of 485 human upper molars with similar anatomical features were selected and randomly distributed across four groups according to the instrumentation procedures performed (G1 and G3: RC; G2 and G4: WO).
