Abstract

A method for concurrent determination o f potassium, total calcium
and chloride concentrations by ion-selective electrodes is described in
this paper. A sample o f whole saliva from the bottom o f the mouth cavity was diluted ten times with magnesium acetate solution (16 mol/
L), which- lead to calcium ionization. This method corresponded well
with reference methods and may be used to determine electrolyte concentration in saliva due to its simplicity. Among three groups of subjects aged 7 - 12 years, the highest calcium concentrations were fo und in the group of subjects affected by dental caries. Concentration variability is highest in calcium concentration, whereas it is lower in other respective electrolytes.

Keywords
