Pengaruh Obat Kumur Daun Sirih Hijau (Piper betle Linn) terhadap Laju Korosi dan Pelepasan Ion Kromium Kawat Ortodonti Stainless Steel

Abstract

The stainless steel wire used in orthodontic treatment may potentially undergo corrosion and release ions, which can have negative effects on both the wire and the human body. Betel leaf (Piper betle Linn) can inhibit corrosion because it contains antioxidant compounds. The purpose of this study is to determine the effect of betel leaf mouthwash (Piper betle Linn) on the corrosion rate and chromium ion release when immersed for 1, 7, and 14 days. This study is a laboratory experimental research. The research samples are 45 pieces of American Orthodontics® stainless steel orthodontic wires with a diameter of 0.016 inches and a length of 6 cm, immersed in soaking solutions, namely artificial saliva, 0.2% chlorhexidine, betel leaf mouthwash (Piper betle Linn) at concentrations of 1%, 2%, and 3%. The samples are stored in an incubator (37°C). The wire samples undergo corrosion rate calculation using the weight loss method, and the solution samples undergo chromium ion (Cr) release testing using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) equipment. The Kruskall-Wallis test results for the corrosion rate, as well as the One-Way ANOVA and Kruskall-Wallis test results for chromium ion (Cr) release in the 5 research groups, show significant differences (p<0.05). The conclusion of this research is that there are differences in the corrosion rate and chromium ion (Cr) release in stainless steel orthodontic wires after immersion in betel leaf mouthwash (Piper betle Linn) at concentrations of 1%, 2%, and 3% for 1, 7, and 14 days.
