Pengaruh Obat Kumur Daun Sirih Hijau (Piper betle Linn) terhadap Daya Lenting Kawat Ortodonti Stainless Steel

Abstract

Stainless steel orthodontic wire is a type of orthodontic wire commonly used in orthodontic treatment. Stainless steel orthodontic wirehas the potential to corrodeand release of constituent metal ions due to the influences of changes in temperature and pH in oral cavity, which result in the a decrease in the quality of the wire so that the resilience of the wire also decreases. This study aimed to determine the resilience of stainless steel orthodontic wires after immersion in artificial saliva, chlorhexidine 0,2%, green betel leaf (Piper betle Linn) mouthwash 1%, 2%, and 3% for 1, 7, and 14 days. This research is a laboratory experimental research. The sample of this research is stainless steel wire (American Orthodontics®) 0,016 inches with a length of 6 cm as many as 75 sample were immersed in 5 groups of immersing solutions, namely artificial saliva, chlorhexidine 0,2%, green betel leaf (Piper betle Linn) mouthwash 1%, 2%, and 3%. The samples were put into an incubator (37oC) for 1, 7, and 14 days and then tested for resilience with a Universal Testing Machine at a speed of 0.5 mm/sec. The results of the One-way ANOVA and Kruskal-Wallis statistical test showed that there was a significant difference between all immersion groups (p<0,05). Post-hoc LSD and mann-Whitney test results showed significant differences (p<0,05) between all pairs at at immersion times of 1, 7, and 14 days. This study concluded that there were differences in the resilience of stainless steel orthodontic wires after immersion in artificial saliva, chlorhexidine 0,2%, green betel leaf (Piper betle Linn) mouthwash 1%, 2%, and 3% for 1, 7, and 14 days.
