Abstract: Untreated orthodontic problems can lead to significant dental public health issues and by means of practitioner’s point of view children and adult patients especially female in the 26 to 40 age can most likely to treat their problems. Orthodontic wires are devices made of a various metal composition used as an anchor to rectify tooth positioning abnormalities. These materials have a longer history than fixed orthodontic procedures, and they have unique characteristics. In the present study Electrochemical analysis by polarization, AC impedance, and surface analysis by atomic force microscopy (AFM) are used to evaluate the corrosion resistance behaviour of Ni-Ti arch wire in artificial saliva (AS) in the presence and absence of vegetable extracts such as Carrot Juice(CJ), Beetroot Juice(BJ) and fruit extract as Pomegranate Juice(PJ) with and without adding sugar(S) has been evaluated which led to the conclusion that the corrosion resistance of the alloy present in various medium decreases in the following order: AS + PJ + S < AS+ PJ < AS + BJ + S < AS + BJ < AS < AS + CJ +S< AS + CJ
