Clinical progress and outcome may be impacted by changes in the mechanical 
characteristics of the materials used in orthodontic appliances, which could also have 
an impact on the appliances' operational characteristics. This paper aims to
investigate the effect of sodium fluoride and chlorhexidine mouthwashes on 
corrosion and surface topography of stainless steel (SS) archwires. In this paper,
three groups were created from the orthodontic archwires collected from patients
who were chosen for inclusion: the control group, which consisted of patients who
maintained good oral hygiene; the fluoride group, which consisted of patients who
used fluoride for intensive prophylaxis; and the chlorhexidine group, which
consisted of patients who used chlorhexidine. Scanning Electron Microscope (SEM)
was used to evaluate representative samples, and after that, high-resolution SEM
pictures were analyzed with Image J software to ascertain surface roughness and
gather data for additional statistical analysis. A significant difference was found 
between the control and the two other groups and a non-significant difference
between the sodium fluoride (NaF) and chlorhexidine (CHX) groups. As a result,
mouthwashes containing sodium fluoride demonstrated more significant surface 
alterations than the control and CHX groups.
