Introduction: The first phase of orthodontic therapy depend on flexible archwires, usually ''Nickel-titanium'' alloy to relate. The substantially load during movement of the tooth. Copper has been additional to nickel-titanium arch wires, subsequent made an alloy with potential clinical benefit. Also, the surface, characteristics, for instance roughness surface, hardness of orthodontic arch wires, and topography are essential determinants of the efficiency of archwire-guided movement of the tooth. They besides affect the potential of corrosion and the aesthetics components of orthodontic.
Aims and objective: This in vitro study was planned to assess the roughness of Copper Nickel Titanium arch wires from altered brands in dry and wet condition (acidic and neutral artificial saliva).
Materials and methods: Three types of CuNiTi orthodontic archwires from different brands were used: CuNiTi (Ormco brand), CuNiTi (IOS brand) and CuNiTi (Orthotechnology brand).
