Mechanical and Metallurgical In Vitro Evaluation of Electropolished Versus Non-Electropolished Rotary and Reciprocating Instruments.

ABSTRACT:

Aim

To evaluate the effect of electropolishing on the mechanical properties of One RECI and One Curve mini nickel-titanium (NiTi) instruments by comparing electropolished and non-electropolished versions of each instrument type.

Methodology

Electropolished and non-electropolished One RECI (reciprocating) and One Curve mini (rotary) NiTi instruments, all manufactured with identical geometry and heat treatment, were evaluated. Instrument design was analysed by light microscopy and scanning electron microscopy, while metallurgical characterisation was performed using energy-dispersive X-ray spectroscopy (EDS) and differential scanning calorimetry (DSC). Mechanical performance was assessed through torsional resistance, bending and buckling load, surface microhardness, and cuttin
