title: [The effect of the aeration status on the corrosion behavior of Ni-Cr alloys].
abstract: Using in vitro tests, the influence of aeration cells that develop in narrow crevices of dental restorations, on the corrosion behaviour of two Ni-Cr alloys (Wiron 88 and Rexillium III) was investigated. The results revealed a 1.6-fold higher ion release in the deaerated part of the electrolyte compared with the aerated one, whereas the ion release was 18-fold higher with Rexillium III. The total analyzed substance loss was 11.1 (S.D. 5.7) and 181.9 (S.D. 48.0) micrograms/cm2, respectively.
