Özet

In this study, effect of fluoride added artificial saliva solution on NiTi and beta-Ti alloys used for orthodontic wires was investigated. The orthodontic wires were immersed into fluoride added artificial saliva solution of pH 4.8 at 37A degrees C. The characterization of metal surfaces after ten days of immersion was carried out using scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). It is concluded that fluoride has an important effect on corrosion behavior of experimental wires that can be described as a type of wear. EDS analysis denotes the existence of a thin oxide film layer in addition to the Ti based oxide one on the surface of the metals.
