[Corrosion of NiCr- and CoCr-containing dental alloys in cellulose-based artificial saliva under in vitro conditions].

It was found that the CoCr alloy is more resistant to the corrosive effects than NiCr alloy. The artificial saliva developed at our clinic increased the passivation range of the both alloys. The higher value observed in the case of the CoCr alloy makes it more suitable for use in patients with xerostomia or an increased risk of allergy.
