Pengaruh Sediaan Obat Kumur Ekstrak Daun Sirih Merah (Piper crocatum) terhadap Laju Korosi dan Kekasaran Permukaan Kawat Ortodonti Nikel Titanium

Abstract

Fixed orthodontic treatment involves orthodontic appliance fixation to the teeth so that it is always in contact with the oral cavity. The condition of the oral cavity is always changing due to internal and external factors, including when gargling. This condition is an ideal environment for corrosion and causes pores in orthodontic wires. Red betel leaf extract (Piper crocatum) has a corrosion inhibitor effect so it is hoped that it can be used as an alternative mouthwash. The purpose of this study was to determine the rate of corrosion and surface roughness of nickel titanium orthodontic wire after immersion in artificial saliva, 0,2% chlorhexidine, red betel leaf (Piper crocatum) mouthwash concentration 1% and 3% for 7, 14, and 21 days. This type of research is a laboratory experimental study. The sample was nickel titanium orthodontic wire with a diameter of 0.016 with a length of 5 cm wich were divided into 12 soaking groups, which is artificial saliva, 0,2% chlorhexidine, 1% red betel leaf mouthwash, and 3% red betel leaf mouthwash, each of it was soaked for 7, 14, and 21 days. Corrosion rate measurements were calculated using the weight loss method and surface roughness measurements were performed with a profilometer. The results of research showed that the highest average corrosion rate and surface roughness was in the 0,2% chlorhexidine group and the lowest average is in the artificial saliva group. The conclusion of this research is 3% red betel leaf (Piper crocatum) mouthwash was superior as a substitute for 0.2% chlorhexidine mouthwash in reducing the rate of corrosion and surface roughness of nickel titanium orthodontic wires.
