SUMMARY
The electrochemical behavior of 18 carat gold in the presence of artificial saliva with and without Aceclofenac100 mg Tablet has been evaluated by AC impedance spectra and Polarization studies. Usually orthodontic wires made of many metals and alloys. After treatment of many food items such as glucose, rasam, sambar,buttermilk etc are taken orally. Many tablets are also orally taken. Aceclofenac100 mg is non-steroidal and anti-inflammatory drug. It is used to treat pain, and inflammation. In the oral environment these orthodontic wires undergo many types of corrosion. In the present study the corrosion behavior of 18 carat gold orthodontic wire in presence of artificial Saliva with a tablet namely, Aceclofenac100 mg orally taken has been investigated by AC impedance spectra and polarization study. Nyquist plots and Bode plots have been drawn. Charge transfer resistance (Rt), double layer capacitance (Cdl) and Impedance values have been calculated. It is observed from electrochemical studies, the corrosion resistance of 18 carat gold electrode increases in presence of artificial saliva with Aceclofenac100 mg. So, people having orthodontic wire made of 18 carat gold need not hesitate to take Aceclofenac100 mg tablet.
