Аннотация

The Ni-Cr and Co-Cr alloys used in dental practice were evaluated for in vitro corrosion resistance in different environments: artificial saliva and fluoridated artificial saliva with pH = 5.2, acidified artificial saliva and fluoridated acidified artificial saliva with pH = 2.5. The environments were chosen to mimic the oral environment with content and pH variations mainly due to the food intake and hygiene products used. The results showed that NaF additions or decreasing the pH value led to a marked decrease in corrosion resistance of both alloys.
