The effect of food simulating liquids on the static frictional forces and corrosion activity of different types of orthodontic wires

Four-week storage in citric acid had the highest deleterious effect, as it significantly increased the static frictional force values of SS, TMA, and NiTi archwires. SS has the highest corrosion activity and thus its frictional force values are affected by 4-week storage in both citric acid and ethanol.
