ABSTRACT

The reliability of the method for analysis for arsenic in dental cements according to the international standard ISO 2590 has been reinvestigated using nuclear tracer techniques and intercomparison of results obtained for the arsenic content of various cements by means of three different methods, i.e. the silverdiethyldithiocarbamate photometric method, neutron activation analysis and atomic absorption spectrophotometry. By means of the two methods first mentioned, results in rough agreement were obtained while the third method, i.e. atomic absorption spectrophotometry revealed lower contents. The interference of antimony in the analysis of arsenic in dental cements was quantitatively assayed.
