【 摘 要 】

The aim of present study is to investigate corrosion resistance of orthodontic wiremade of Ni-Ti Super Elastic Shape Memory alloy in artificial saliva in the presence ofLimcee-500 mg and Shelcal-500 mg has been evaluated by polarization study and ACimpedance spectra, artificial saliva taken as control. It is observed that in presence of theLimcee-500 mg the corrosion resistances of Ni-Ti SESM alloy increases. On the other hand inthe presence of the Shelcal-500 mg the corrosion resistances of Ni-Ti SESM alloy decreases.Corrosion resistance increases due to linear polarisation resistance increases and corrosioncurrent values decreases. It is suggested that people implanted with orthodontic wire made ofNi-Ti SESM alloy need not hesitate to take Limcee-500 mg but Shelcal-500 mg should avoidorally. The increase or decrease in corrosion resistance of Ni-Ti SESM alloy in presence ofthese tablets in artificial saliva is due to the ingredients present in tablets.
