Orthodontic wire of many alloys and metals are used by dentists. These wires may undergo corrosion in the oral environment and in presence of food items we take orally. The corrosion resistance of thermo active Ni-Ti Super elastic shape memory alloy vs. 22 K Gold alloy in Artificial Saliva (AS) in presence of Jamun (Naaval pazham or Syzygium cumini) Fruit Extract (FE) has been evaluated by Polarisation study. When corrosion resistance increases linear polarization resistance value increases and corrosion current decreases. It is observed that for thermoactive alloy, the LPR value decreases in the following order: AS>AS+FE (10 ml)>AS+FE (20 ml)>FE. For 22 K Gold system, the LPR value decreases in the following order: AS+FE (20 ml)>FE>AS+FE (10 ml)>AS. In Artificial Saliva Thermoactive alloy is more corrosion resistant than 22 K Gold. In FE 22 K Gold is more corrosion resistant than Thermoactive alloy. In AS+FE (10 ml) 22 K Gold is more corrosion resistant than thermoactive alloy. In AS+FE (20 ml) 22 K Gold is more corrosion resistant than thermoactive alloy.
