Abstract: Corrosion resistance of orthodontic wire made of SS 316L alloy in artificial saliva in the absence and presence of five tablets namely, Limcee-500mg, Shelcal-500mg, Ferikind, Cefixime-200mg, Biogenetic (Aluminium Hydroxide And Magnesium Trisilicate), has been evaluated by polarisation study and AC impedence spectra. It is observed that in the presence of the tablets Ferikind and Biogenetic (Aluminium Hydroxide and Magnesium Trisilicate) the corrosion resistance of SS 316L alloy increases. On the other hand in the presence of the tablets Limcee- 500mg, Shelcal-500mg and Cefixime-200mg the corrosion resistance of SS 316L alloy decreases. Hence it is recommended that people implanted with orthodontic wires made of SS 316L alloy need not hesitate to take the tablets Ferikind and Biogenetic (Aluminium Hydroxide and Magnesium Trisilicate) orally. People having implanted with orthodontic wire made of SS 316L should avoid taking tablets Limcee-500mg, Shelcal-500mg and Cefixime-200mg. The increase in corrosion resistance or decrease in corrosion resistance of SS 316L alloy in the presence of these tablets in artificial saliva is due to the ingredients present in tablets.

Keywords: orthodontic wires, artificial saliva, tablets, corrosion resistance, polarisation study and AC impedence spectra.
