title: [Determination of the corrosion resistance of dental alloys with a new measurement method].
abstract: A corrosion sensor newly developed by the Swiss Society for Corrosion, modified for a potential application in the oral cavity, was tested in vitro. By measuring the impedance with a special sensor in the size of a bur handpiece, it allows a quick determination of the corrosion resistance. For the evaluation of the method, measurements were done on six conventional dental alloys (two precious alloys, one Pd-based alloy and three non-precious alloys) which had been tested in crevice corrosion by the authors in an earlier stage. Qualitatively the results are quite in concordance with the ones got with the usual tests. On the base of the present results the use directly in the oral cavity of this corrosion test method appears to be very promising.
