    Author(s): Heba Abdul Jabbar Nema* and Shaymaa Shaker Taha

    Introduction: Nickel titanium orthodontic archwires are widely used due to their favourable characteristics mainly in levelling and alignment stage. Gingivitis and enamel demineralization are commonly encountered side effects of fixed orthodontic treatment. Mouthwashes are prescribed as adjunct aids for good oral hygiene but their prolonged use may result in corrosion of orthodontic appliances. Aim: The current study was designed to evaluate corrosion of Rhodium coated and conventional nickel titanium orthodontic archwires in different commercially available mouth washes. Materials and methods: Samples of rhodium coated and un-coated nickel titanium wire were immersed in four media (Listerine cool mint, Listerine total care zero, silca and distilled water as a control group) for two months. The atomic force microscopy .. Read More»
