Some instruments such as stereomicroscopy and scanning electron microscopy are used to observe corrosion of endodontic files which are complicated and dependent on preparation methods. Having knowledge of the corrosion and ion release of endodontic files can help in drawing firm deductions as to which files would perform better in the clinical scenario. Therefore, we have used energy dispersive <jats:styled-content style=\"fixed-case\">X<\/jats:styled-content>\u2010ray analysis and an atomic absorption spectrophotometer to track oxygen on the surface and iron in the exposed media to observe the oxidative rate of the media. In this study, corrosion by blood was higher than other biological fluids, but less than with sodium hypochlorite (<jats:styled-content style=\"fixed-case\">N<\/jats:styled-content>a<jats:styled-content style=\"fixed-case\">OC<\/jats:styled-content>l). Observations of energy dispersive <jats:styled-content style=\"fixed-case\">X<\/jats:styled-content>\u2010ray analysis and atomic absorption spectrophotometer results demonstrated that after exposure the amount of oxygen on the surface and surrounding areas increased. Therefore, the files should be rinsed as soon as possible during and after use to hinder the oxidation rate, but blood may produce a different behavior and it might be considered as a decreased risk of broken stainless steel files remaining in the root canal after treatment.
