The fixed orthodontic appliances are subjected to corrosive damage which acts to degrade the physical properties and increase the potential for failure. The oral environment because of its enzymatic phenomenon is an ideal climate for corrosive attack of orthodontic appliances. This gradual destruction of materials resulting from chemical reactions can have several adverse effects such as the release of elements from metals‚ roughening of wire surface‚ and weakening of appliances‚ which can lead
