| Popis: | The objective of this study was to determining the level of released chloride ions from conventional glass-ionomer cements incorporated with two different types of antimicrobial agents - cetylpyridinium chloride and benzalkonium chloride, as well as to see the influence of incorporated antimicrobial agents on the process of chloride ions releasing. Two conventional glass-ionomer cements ChemFlex and Fuji IX were incorporated with a different percentage of the antimicrobial agents. The specimens were prepared according to the British Standards Institution Specifications for Dental Glass Ionomer Cements. 84 samples in total (4 mm × 6 mm) were prepared - by six specimens of the conventional glass-ionomer cements Fuji IX and ChemFlex with various concentrations of antimicrobial agents added - 1%, 2% and 3%, i.e. six samples for each antimicrobial agent and each concentration level, as well as, by other six samples of the same cements without any antimicrobial agents, to be used as a control group. The measurements were performed at 14 successive time intervals started in zero time and finished after seven days. The results obtained speak of a continual release of chloride ions from both analysed glass-ionomer cements with the addition of antimicrobial compounds, as well as with no antimicrobial compound incorporated. |
