Abstract

The inhibition potentials of five toothpastes (Vicco, Dant Kanti, Sparkle Fresh, Emoform R and Colgate Visible White) was investigated by evaluating the corrosion behaviour of orthodontic wires made of 18 ct gold, SS 316 L, 22 ct gold, SS 18/8 and NiTi shape memory alloy immersed in artificial saliva solution containing 1% toothpaste. Linear polarization resistance, corrosion current, charge transfer resistance, double layer capacitance and impedance were utilized to evaluate the corrosion resistance and adsorption properties of the toothpaste. UV-visible absorption spectroscopy, Fourier transform infrared spectroscopy, fluorescence spectroscopy, scanning electron microscopic studies, electron dispersive X-ray spectroscopy and atomic force microscopy provided the confirmatory evidence of improved surface condition due to adsorption for the corrosion protection. The impedance measurement has shown that the change in the impedance parameters like charge transfer resistance with the addition of extract is due to the adsorption of active molecules leading to the formation of a protective layer on the surface of the orthodontic wire. NiTi shape memory alloy has shown highest percentage of inhibition efficiency (η% of 98% and 97%) in the electrochemical analysis in the presence of Colgate Visible White toothpaste. Sparkle Fresh toothpaste has offered highest corrosion resistance to three of the alloys namely SS 316L, 22ct gold and SS 18/8
