Perbandingan Penurunan Kekuatan Elastomeric Chain Ortodonti dalam Perendaman Obat Kumur Chlorhexidine, Fluoride, dan Daun Sirih Hijau (Piper betle Linn) pada Interval Waktu yang Berbeda

Abstract

The use of elastomeric chains in patients with fixed orthodontic appliances will always be in contact with oral cavity conditions such as saliva, temperature and changes in pH which can cause a reduction in the force of the elastomeric chain. The aim of this study was to determine the reduction in elastomeric chain strength after immersion in artificial saliva, chlorhexidine 0,2%, fluoride 0,05%, green betel leaf (Piper betle Linn) 1%, 2%, and 3% mouthwash for 1, 7, 14, 21, and 28 days. This research is a laboratory experimental research. The sample of this study was a American Orthodonti® brand elastomeric chain as many as 90 samples cut along 5 lumens with a withdrawal length of 18mm and immersed in sartificial saliva, chlorhexidine 0,2% , fluoride 0,05%, green betel leaf (Piper betle Linn) 1%, 2%, and 3% mouthwash were put into an incubator (37⁰) for 1, 7, 14, 21, and 28 days, then measured the strength of the elastomeric chain using a force gauge brand Soonda®. The results of the Kruskal-Wallis statistical test showed that there were significant differences between all immersion groups for 1, 7, 14, 21, and 28 days (p<0.05). The conclusion of this study is that there are differences in the reduction in elastomeric chain strength after immersion in artificial saliva, chlorhexidine mouthwash 0.2%, fluoride 0.05%, green betel leaf (Piper betle Linn) 1%, 2%, and 3% for 1, 7, 14, 21, and 28 days.
