“…Results in several published papers have shown similar biocompatibility of austenitic and austenitic-ferritic steel. The replacement of austenitic stainless steel with austenitic-ferritic in orthodontic treatments reduces costs and nickel hypersensitivity in patients [9][10][11][12][13][14].…”

Anodic and spontaneous corrosion of different types of stainless steel (AISI 304L, AISI 316L and 2205 DSS) in phosphate-buffered saline solution (PBS, pH = 7.4) at 37 °C (i.e., in simulated physiological solution in the human body) were examined using open circuit potential measurements, linear and cyclic polarization, and electrochemical impedance spectroscopy methods. After the anodic and spontaneous corrosion, the surface of the tested samples was investigated by light and scanning electron microscopy (SEM) with EDS analysis. It has been established that the tendency of the examined steel materials towards local corrosion decreases in the order: AISI 304L < AISI 316L < 2205 DSS. Namely, the possibility of repassivation and the resistance to local corrosion increases in the same order. The corrosion resistance of steel samples at open circuit potential is a consequence of forming a natural oxide film with a bi-layer structure and consists of an inner barrier and an outer porous film. The inner barrier film has a small thickness and extremely high resistance, while the outer porous film is much thicker but also has significantly lower resistance. The inner barrier layer mainly prevents corrosion of examined steel samples in order: AISI 304L < AISI 316L < 2205 DSS. Light microscopy and SEM/EDS analysis after pitting and spontaneous corrosion showed damage on the AISI 304L and AISI 316L surface, while the surface of 2205 DSS was almost undamaged by corrosion.

“…Corrosion resistance of various metals and alloys in artificial saliva in the presence and absence of various tablets, food additives etc have been investigated. Metals and alloys such as Titanium Alloy, stainless steel, SS 316L have been studied [1][2][3][4][5][6][7][8][9][10]. El Kouifat et al have investigated the fretting-corrosion of orthodontic arch-wire/ bracket contacts in saliva environment.…”

The corrosion resistance of SS 316L alloy in artificial saliva, in the absence and presence of Amlodiphine-2.5 mg has been evaluated by polarization study and AC impedance spectra. Polarisation study reveals that in the presence of Amlodipine-2.5 mg, LPR value increases and corrosion current decreases. In presence of Amlodipine-2.5 mg mg, the corrosion resistance of SS 316L alloy in artificial saliva increases. AC impedance study reveals that in the presence of Amlodipine-2.5 mg, R t value increases and C dl decreases. In the presence of Amlodipine-2.5 mg the corrosion resistance of SS 316L alloy in AS increases. From the present study it is concluded that people clipped with orthodontic wire made of SS 316L alloy need not hesitate to take Amlodipine-2.5 mg orally.
