Abstract

Metals used in dentistry in various forms such as metallic curative materials in the mouth, all metals may have the tendency to undergo tarnish or corrosion. The percentage of corrosion varying from metal to metal. Stainless steel and many other types of metal alloys are being used for the orthodontic treatment, which undergo chemical or electrochemical reaction with the oral environment. Here, polarization and alternating current impedance spectrums have been investigated for inhibiting corrosion of stainless steel in presence of fake saliva with and without green tea. Polarization investigation shows that the value of a linear polarization resistance is enhanced, the value of corrosion is decreased and the value of the alternating current impedance is increased by the amount of the CDL. Atomic force microscopic techniques reveals that the decrease in average roughness value on the stainless steel surface in artificial saliva + Green tea medium. The present survey shows that the persons cut with stainless steel orthodontic wire may drink oral green tea without concern.
