title: [Metals and alloys--corrosion, toxicology, sensitivity reactions 1].
abstract: Alloys used in dentistry should not compromise the health of patients and of dental personal. All aspects of biocompatibility, such as corrosion, toxicity and allergic sensitization should be considered when base metal alloys or low gold alloys are used. In regard to health legislation, alloys should considered to be 'drugs'. Hazardous alloys should not be recommended, if the primary concern is cost. However, there is no or only little evidence to show, that either of the alloy systems used would rise health risks, exempting the beryllium containing alloys. They should not be used any longer. Probably, dental technicians are endangered by beryllium more than patients are. Some of the Ni-Cr-alloys were shown to corrode. There is less evidence of allergic senzitization caused by nickelcontaining dental alloys, than suspected first.
