AbstractTo evaluate, for the first time, the effect of the Moroccan Miswak (Salvadora persica) extract on the corrosion behavior of Ni-Cr dental alloy in artificial saliva, the electrochemical techniques, such as Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES), surface analysis, and metal release were investigated. Data extracted from the obtained electrochemical corrosion tests demonstrated that the resistance to corrosion of Ni-Cr alloy was improved in presence of Miswak extract at various concentrations, due to the protective action created by the adsorption of Miswak extract on the Ni-Cr alloy surface; the concentration of 1000 ppm presents a corrosion inhibition efficiency of 87%. In presence of the Miswak extract, the SEM-EDS and XRD studies confirm the formation of a film on Ni-Cr dental alloy surface and revealed a reduction in the relative dominance of Ni and Cr on the alloy surface. Also the release of Ni, Cr, and Mo ions has been obviously decreased.
