CORROSION RESISTANCE OF SS18/8 ALLOY, GOLD 18CARAT, GOLD 22 CARAT AND SS316L ALLOY, IN ARTIFICIAL SALIVA IN THE ABSENCE AND PRESENCE OF VITAVION FORT (VITAMIN B COMPLEX) TABLET 500MG

ABSTRACT
Corrosion resistance of orthodontic wire made of SS18/8 alloy, Gold 18 carat, Gold 22 carat and SS316L alloy in
artificial saliva (AS) in the absence and presence of Vitavion Fort tablet 500 mg has been evaluated by
electrochemical study such as polarization study. Polarization study leads to the conclusion that corrosion
resistance of Gold 18 carat and Gold 22 carat decreases in the order: AS + Vitavion Fort > AS. Hence, people
clipped with orthodontic wire made of Gold 18 carat and Gold 22 carat can take Vitavion Fort tablet orally without
any hesitation. For SS18/8 alloy and SS316L alloy polarization study leads to the conclusion that corrosion
resistance of SS18/8 alloy and SS316L alloy decreases in the order: AS > AS + Vitavion Fort. So, people clipped
with an orthodontic wire made of SS18/8, SS316L alloys should avoid taking Vitavion Fort tablet orally.
Keywords: Corrosion resistance, polarization study, orthodontic wire, SS18/8 alloy, SS316L alloy, Gold 18 and 22 carat, Vitavion Fort.
