Pengaruh Sediaan Obat Kumur Ekstrak Daun Sirih Merah (Piper crocatum) dalam Menghambat Pelepasan Ion Nikel pada Kawat Ortodonti Stainless Steel

Abstract

Orthodontic treatment takes a long time, cause wire contact with the oral environment, causing corrosion. One factor that triggers corrosion is the use of mouthwash. Red betel leaves (Piper crocatum) contain secondary metabolites, one of which is tannin, which functions to inhibit the corrosion process. This type of research is laboratory experimental. The sample for this study was a round stainless steel orthodontic wire with a diameter of 0.016 inches and a length of 5 cm. The samples were divided into 4 groups, orthodontic wire immersed in artificial saliva (group 1), chlorhexidine 0.2% mouthwash (group 2), Total Care mouthwash (group 3), and red betel leaf extract 2% mouthwash (group 4). All wires immersed in all groups of solutions were stored in an incubator at a temperature of 37oC. The aim of this study was to determine the amount of nickel ions released from stainless steel orthodontic wires in group 1, group 2, group 3, and group 4 for subgroups with soaking times of 7, 14, and 21 days. The amount of nickel ion release was measured using the ICP-OES. The results showed that the entire group had significant One-way ANOVA and Posthoc LSD test results on the effect of ingredients and time (p≤0.05). The highest ion release was in group 2 for all subgroups with mean ion release of 0.0617±0.00115, 0.0579±0.00017, and 0.0552±0.00077. It can be concluded that the amount of release of nickel ions immersed in group 4 is lower than group 2 and group 3.
