Effect of EDTA, NaOCl, and HEDP-based irrigants on the mechanical properties of heat treated NiTi endodontic instruments
No significant differences were found in maximum bending or torsional torque across irrigant groups. However, EDTA exposure resulted in increased angular deflection at fracture, followed by distilled water. NaOCl showed the lowest angular deflection, while NaOCl-HEDP exhibited intermediate behavior. Heat-treated instruments, particularly S.Wire, consistently showed superior mechanical performance across all test conditions.
