AbstractThe objective of the current study was to investigate the release of Ag and Hg ions from filing. Four commercial fillings were used in the experiments, all fillings samples, disc with diameters of 10 mm and thickness 3mm were used, made by the manufacturer.Four samples of carbonated beverages (Pepsi, Seven – up, Merinda, and Sinalco) were used for each tested filling and tasted with times.
The ion release from above tasted filling in the above mentioned carbonated beverages was measured over 4 time intervals, i.e. after 0, 1 , 24 hours and 7 days respectively. Carbonated beverages were analyzed by atomic absorption spectrophotometer. Results show that Ag and Hg filling released great amounts of Ag and Hg ions in all four carbonated beverages so that on the very first time of measurement these amounts exceeded the approved daily dietary intake of this elements. Gradually, the amount of the released Ag and Hg ions increased with great variability in all carbonated beverages.
