Abstract:
Objective: To study the corrosion resistance of the ortho do ntic magnets with titanium nitride (TiN) coating. Methods: The m agnets coated TiN film were immersed into artificial saliva at 37 ℃ for two mon ths. During the immersion, the concentration of iron ion in the artificial saliv a was analyzed with atomic absorption spectrophotometry(AAS). After immersion, t he weight change of the magnets was measured.The magnets coated with nickel film and without coating were used as the controls.Results: In all t he groups, iron ion concentration in the artificial saliva increased with the in crease of immersion time(P
