The Effect of Banana Peel Extract (Musa Paradisiaca) in Inhibiting The Corrosion Rate of Orthodontic Wire and Stainless Steel Bracket

Abstract

Orthodontic treatment is a long-term treatment using a device with the main components are orthodontic brackets and wires which are generally made of stainless steel. These components can undergo a process of corrosion in the oral cavity. Banana peel contains antioxidants which can be used as natural inhibitor ingredients in inhibiting the corrosion process. This study aimed to determine the effect of banana peel extract (musa paradisiaca) in inhibiting the corrosion rate of orthodontic wire and stainless steel bracket. This research is a laboratory experimental study with a post test with control group design design using orthodontic wire and stainless steel bracket with a sample size of 5 with a wire diameter of 0.016 mm. This sampel was divided into 5 groups with media in the form of artificial saliva, namely 1 group without treatment and 4 groups with concentrations of banana peel extract 4500 ppm, 5000 ppm, 5500 ppm and 6000 ppm. The measurements of the release of Fe, Cr and Ni ions were carried out using Atomic Absorption Spectrophotometry (AAS). The results showed the addition of banana peel extract had a significant effect (p<0.05) in inhibiting the release of orthodontic wire nickel ions and stainless steel bracket. The release of metal ions (Fe, Ni, Cr) has a negative correlation, meaning that the higher the ppm, the lower the level of metal ions released. Banana peel extract has an effect in inhibiting the corrosion rate of orthodontic wire and stainless steel bracket.
