| dc.description.abstract | Stainless steel orthodontic wire is a commonly used type of wire in orthodontic
treatments. The use of mouthwash is recommended by doctors to help control the
accumulation of plaque and bacteria, however mouthwash can affect the corrosion
process of stainless steel wires so it needs to be inhibited with a mouthwash that has
inhibitors during use. The objective of this research is to determine the efficacy of
mouthwash extracted from ethanol of red betel leaves (Piper crocatum) in inhibiting
the corrosion rate and microstructure changes of stainless steel wire after immersion
for 7, 14, and 21 days. This study is an experimental laboratory research with a posttest
only control group design. The samples used are 0.016-inch diameter and 5 cm
long stainless steel wires. The samples are divided into four groups: Group 1,
orthodontic wire immersed in artificial saliva solution; Group 2, immersed in 0.2%
chlorhexidine; Group 3, immersed in Total Care green betel leaf mouthwash; and
Group 4, immersed in mouthwash with 2% ethanol extract of red betel leaves (Piper
crocatum). Corrosion rate testing is conducted using the weight loss method, and the
analysis of microstructure changes in the wire is performed using a Scanning Electron
Microscope (SEM). The average corrosion rate results show a significant difference
between artificial saliva solution, 0.2% chlorhexidine mouthwash, Total Care green
betel leaf mouthwash, and 2% ethanol extract of red betel leaf (Piper crocatum)
mouthwash for 7, 14, and 21 days (p<0.05). SEM analysis results reveal differences in
the microstructure on the surface of stainless steel wire after immersion in artificial
saliva solution, 0.2% chlorhexidine, Total Care green betel leaf mouthwash, and 2%
ethanol extract of red betel leaf (Piper crocatum) mouthwash for 7, 14, and 21 days. | en_US |
