he 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
