“…Additional release of metal ions above saliva after exposure to oral antiseptics is reported earlier, higher in those based on alcohol and fluorides than chlorhexidine, and least in aqueous solutions of herbal extracts . Ion release could be also related to microstructure of the alloy . In addition to nickel allergies, newer studies have reported allergies to titanium .…”

The aim was to explore the influence of the interaction of oral antiseptics and various coatings on the corrosion behavior of nickel‐titanium (NiTi) orthodontic alloys. NiTi archwires with uncoated, rhodium‐coated, and nitride‐coated surface were exposed to artificial saliva pH 4.8 at the temperature of 37 °C, and to saliva with the addition of three commercial oral antiseptics (Curaspet, Gengigel, and Listerine). Electrochemical impedance spectroscopy and cyclic polarization were performed. Released nickel and titanium ions after a period of 7 days were measured by inductively coupled optical emission spectroscopy. Results demonstrate that the rate and degree of corrosion mainly increase with the addition of antiseptics. Electrochemical impedance spectroscopy indicates the biggest corrosion resistance in Gengigel. Rhodium‐coated NiTi demonstrates higher corrosion rate in saliva and in all antiseptics than uncoated and nitride‐coated NiTi. The highest tendency toward localized corrosion is seen in rhodium‐coated NiTi in all media, and least in nitride‐coated NiTi. The release of titanium ions mainly supports findings of general corrosion rate. These results indicate that both antiseptics and coating modify corrosion.

“…For Briceno et al [17], the presence of martensite improves corrosion resistance and decreases the release of nickel into the saliva at 37°C. Because of the number of involved factors, it is difficult to see this in the present study.…”

Most of orthodontic alloys contain nickel. The consumption of acidic drinks may have an impact on these alloys in particular with respect to corrosion resistance. The corrosion is accompanied by nickel ion release that can generate hypersensitivity reactions. This study will quantify the release of nickel ions from orthodontic wires of stainless steel and nickel-titanium submitted to a bending constraint after a static immersion in acidified medium. Wire segments from Nickel-Titanium and stainless steel of which some are submitted to a bending constraint are immersed in acid media and then immersion solutions are analyzed using the inductive coupling plasma mass spectrometer (ICP-MS) with a detection threshold of 0.5ppb (μg/L). Nickel ions were detected in all analyzed samples. The results range from 2.4ppb to 9404ppb. Even with constraint, the release of nickel would be well below the level of daily food intake. The corrosive behavior depends on the properties of material, the manufacturing process, the environment, the pH values and the constraints. The surface condition is an important factor for corrosion. More the surface is rougher and the more likely it is to be attacked by corrosion especially by injection corrosion. The manufacturers should take this issue into account.
