[Influence of corrosion products of the dental alloys on the excitable tissues].
The surface of dental alloys in contact with well conducting electricity solutions are electrochemically corroded. This phenomenon is determined by a proper electric wave generated by electrochemical phenomena present at the limit between the two phases. Because during dental treatments similar conditions with the generation of corrosion waves are present, we decided to study the electrochemical behaviour of the most commonly used dental alloys. The method used in our study is based on the anodic and catodic reactions developed simultaneously, represented by the global curve of polarization that gives informations on the intensity of corrosion waves. We have also studied the influence of corrosion products on the excitable tissues. The results demonstrate the significant influence of metallic ions on the excitable tissues.
