Abstract

The article presented data on the role of selenium in the human body, was shows the significance of its deficiency in the occurrence of various pathologies, including inflammatory periodontal diseases. The perspective of salivadiagnostics was shown. The experience of selenium determination in biological objects was generalized. Data were provided on the main methods for the determining trace elements, including selenium, in biological substrates are given, and their comparative analysis was carried out. General methodological approaches to the determination of chemical elements in biological environments were discussed. The fluorimetric method for the determination of selenium in biological objects is considered as the preferred method, taking sensitivity, selectivity and cost into account.
