Abstract

Stainless Steel Alloys for Dental Application: Corrosion Behaviour in the Presence of Toothpaste Vicco

Author(s): Renita D Souza, Amit Chattree, Susai Rajendran

Stainless steel 18/8 and 316L have been widely used in orthodontic implants. The patients are recommended to pay attention to oral hygiene by prescribing the toothpastes to improve oral health. People face problems of corrosion of the material due to the use of various toothpastes. Our study was aimed at evaluating the corrosion behaviour of orthodontic wires made of SS 18/8 and SS316L in the absence and the presence of toothpaste Vicco. The electrochemical studies such as potentiodynamic polarization and AC impedance spectra were used to know the corrosion parameters such as corrosion potential (Ecorr), corrosion current (Icorr), Linear Polarization Resistance (LPR), charge transfer resistance (Rct) and double layer capacitance (Cdl). In the presence of toothpaste Vicco, both the alloys under investigated showed high corrosion resistance. The decrease in the corrosion resistance of SS 18/8 and SS316L alloy in various solutions was in the following order: artificial saliva+toothpaste>toothpaste>artificial saliva. In the presence of artificial saliva containing 1% toothpaste the corrosion resistance of SS 18/8 was greater than SS 316L alloy. This was due to the co-ordination of stainless steel metal ion with the active principles of the ingredients of the toothpaste forming a protective layer on the surface of the metal and thus resisting corrosion.
