Sažetak
In a moist environment electrochemical conditions lead to release of metal ions into the patient's saliva. The aim of this study was to examine and compare the types and quantities of metal ions released from two alloys: AuPt alloy and Co-Cr-Mo alloy under in vitro conditions, imitating artificial saliva. We soaked ten sets of Au-Pt
alloy pieces having 133 mm2 exposure surface and ten sets of Co-Cr-Mo alloy (WironitR, Bego, Germany) pieces having 497 mm2 exposure surface for 1, 2, 3, 4, 5, 6, 7, 14, 21 and 30 days (six pieces each set) in phosphate buffered saline (pH 6.0) to mimic dental saliva. TE in the phosphate buffered saline (saliva) were assessed by ICP-AES (JY 50P, Jobin-Ywon, France) with the detection
limit of 10 mg/L. We found detectable amounts (mg/L) of TE (Mean SD) released from Au-Pt alloy (Mean SD): Zn 124 (51), Cu 53 (63), Fe 15 (11) and Cr 18 (25) and detectable amounts of TE released from Co- Cr-Mo alloy (Mean SD): Co 337 (170), Fe 21 (15) Zn
87 (56), Ni 41 (68), and Cr 49 (42). The manufacturer did not indicate the presence of Zn and Fe in the Au-Pt alloy and the presence of Fe, Zn, and Ni in the Co-Cr- Mo alloy. Significantly higher amount of Zn was released from high noble AuPt alloy than from Co-Cr-Mo alloy (p<0.05) and a significantly higher amount of Cr was
released from Co-Cr--Mo alloy than from Au-Pt alloy. There was no significant difference in the amount of Fe ions released between the two alloys (p>0.05). We must keep in mind that the amount of released TE may be much higher than the reported values after laboratory procedures (casting, polishing, etc.) and, moreover, other TE may become detectable.
