    Introduction: Friction plays a role in reducing the efficiency of orthodontic tooth movement, so it is necessary to understand the effect of friction and the amount of force needed to overcome its impact on biological tissue response and archwireguided tooth movement. Aim: the purpose of this study is to compare between two different wires: NiTi, Blue NiTi and CuNiTi by measuring the sliding friction and surface roughness. Materials and Methods: specimens were divided into nine groups (six specimens each) the groups were classified according to the type of the wire and treatment condition (as received, thermocycling of 5000 cycle, distilled water aging for 1month). The groups were tested for sliding friction in dry condition. Surface roughness of five samples of each group was examined by means of atomic force microscope. The data.. Read More»
