摘要

The Orthodontic Wire has a stainless steel metal content that can undergo corrosion on the inside of the mouth. Corrosion can be influential, bad for the human body and can release ions that can affect the process of corrosion. Stainless steel wire can release chromium ion and ways to reduce the rate of corrosion of materials by using inhibitors. Inhibitors can be extracts from natural materials and are not harmful to the environment. One of them is the extract of star fruit wuluh that has active content can stabilize ions of chromium on the surface of the stainless steel wire and can form a passive layer so that corrosion can be inhibited. To know the ability of inhibition the star fruit wuluh extract power to prevent corrosion on Stainless Steel wire. Materials used artificial saliva and fluid extract of star fruit wuluh. The research was conducted in experimental laboratories with 4 sample treatment group using the extract of star fruit wuluh and 4 sample control group using artificial saliva fluids. The release of chromium ion Atomic Absorption Spectrophotometric instruments used. Cr metal ion release Occurs with the amount of discharge varies from the treatment group and the control group on day 1, 3, 7 and 14 days. An increase in the amount of deposition of chromium ion on each sample research. The release of chromium ion from Stainless Steel wire that is soaked in the extract of star fruit wuluh less than immersed in artificial saliva. Extract of starfruit wuluh have corrosion inhibition against stainless steel wire.
