The inhibition and surface protection of inhibitors (Limcee, Shelcal) on 22karat gold bracket evaluated by polarisation and AC-Impedance spectra. The electrochemical test analysis showed corrosion resistance increases incidence of Limcee tablet due to LPR (Linear Polarisation Resistance), Rct (Charge transfer resistance) values increases and corrosion current (I-corr) density, Cdl (Double layer capacitance) values decreases. But corrosion resistance decreases incidence of Shelcal tablet due to LPR, Rct values decreases and I-corr, Cdl values increases (compare with artificial saliva). Decrease or increase inhibition efficiency of 22karat gold brackets is due to the presence components of tablets (Limcee, Shelcal). Polarisation test reveals, Limcee and Shelcal perform is mixed (anodic & cathodic) type inhibitors. Its result of studies suggest corrosion resistance of 22karat gold bracket in artificial saliva order is Limcee > AS > Shelcal.
