[Nickel solubility and metallic taste]

Main causes for metal taste may be deficiency diseases (especially deficiency of zinc), medication or dental restorations. Saliva of probationers with partial dentures was analyzed for their nickel contents. The solubility behavior in saliva of the alloys studied was related to metal taste and burning sensation. For most alloys the frequency of metal taste was in accordance with the nickel solubility in saliva.
