Sažetak
Dental materials such as orthodontic archwires should be corrosion resistant to saliva but also to other compounds that can come in contact with them like agents for oral hygiene. Lately, it has been recommended that, in addition to improved oral hygiene, orthodontic patients should use probiotic supplements to decrease the incidence of caries and gingivitis as the most frequent side effects of long-term orthodontic therapy. For this reason, the objective of this work was to examine how the use of probiotic supplements affects corrosion stability of orthodontic archwires made of nickel-titanium alloy (NiTi). Studies have been conducted in artificial saliva and in saliva with dissolved tablets of commercial oral probiotic. Electrochemical measurements (electrochemical impedance spectroscopy, potentiodynamic polarization) showed that probiotic tablets increase the possibility of localized corrosion. However, it was not clear if the localized corrosion was caused by microorganisms or due to the deposits of insoluble tablet components. For that reason samples were exposed to artificial saliva containing Lactobactilus reuteri. After 2 weeks of exposure they were characterized by electrochemical methods and electron microscopy in order to evaluate the impact of studied microorganisms on their corrosion stability.
