Sažetak
Cytotoxicity is in direct correlation to the level of ion release, with non-precious alloys having higher ion release than that of precious alloys. The most often used non-precious dental alloy is Ni-Cr alloy.
The aim of the investigation was to determine the type and quantity of ions released from Ni-Cr alloy (Wiron 99(r), Bego, Germany), in acid solutions with different pH values, and to determine the influence of the type of acid solution, its pH value, and duration of interaction on ion release. The overall sample consisted of 180 pieces of
Ni-Cr alloy, 60 samples submerged in each of three different solutions (buffered phosphate solutions pH 3.5 and pH6, and lactic acid solution pH 3.5). Quantity of ion release was measured on solution samples taken at 10 different time intervals by means of the ICP-AES method. Average release of Ni ions in lactic acid solution was
432.42 μg/L, while the highest average Ni+ ions release of 541.67μg/L was measured in buffered phosphate solution pH 6.0. MANOVA demonstrated significant influence of the type of solution on Ni ion release (p<0.01), while the time of exposure was not a significant factor (p=0.23). Zn ions demonstrated the lowest average ion release (88.95 μg/L, phosphate solution pH 3.5). Statistically
significant influence of the type of solution and pH value on ion release was determined, except for chromium ions (p<0.05). Dentobacterial plaque acidity is sufficient to start corrosion of Ni-Cr dental alloys.
