Abstract: Teeth that are well-aligned are viewed as attractive, but some individuals have naturally irregular teeth alignment. To correct this, orthodontists use wires. After the wires are placed, patients eat various foods, drink beverages, and take tablets orally, which can pose a risk to the wires. Moreover, the wires can corrode upon contact with saliva. This research investigated the corrosion resistance of orthodontic wires crafted from thermo-active alloy in artificial saliva, with and without the addition of Rexidin SRS mouthwash, through a polarization study. The corrosion properties of the Ni-Cr alloy were assessed for the following systems: Artificial Saliva system and Artificial Saliva + Rexidin SRS mouthwash system. The experiment included the measurement of Linear Polarization Resistance (LPR) and corrosion current values. The research yielded the following findings. The hierarchy of corrosion resistance in Ni-Cr alloy orthodontic wire is ranked as follows: Artificial Saliva > Artificial Saliva combined with Rexidin SRS mouthwash. This suggests that individuals utilizing Ni-Cr Orthodontic wire should refrain from using Rexidin SRS mouthwash.
