两种镍基口腔修复合金在漱口水中镍离子析出的比较
Comparative study on nickel release of two dental nickel alloys in mouth wash
摘要
Abstract
Objective This study aims to investigate the release of nickel from two nickel alloy specimens for dental prosthesis in a commercial mouth wash through a constant immersion experiment. Methods Standard samples were casted from two different alloys and ground to achieve the same roughness. For our experimental group, one-half of the samples are immersed in a solution composed of artificial saliva and commercial mouthwash. For our control group, the other half of the samples are placed in a solution containing artificial saliva and distilled water. This procedure is performed at (37± 1) °C for 96 h. The amount of Ni ion released after the 96 h immersion test and the changes in the surfaces of the alloys as-received and upon immersion are then determined by using an inductively coupled plasma optical emission spectrometer (ICP-OES) and a scanning electron microscope. Results The amount of released Ni ion is below the minimum detection limit of ICP-OES in the blank solution without the alloys. More ions are released from the Ni-casted alloy than from the Ni-Cr porcelain fused to a metal in the experimental group and the control group. The ions released from each alloy are also significantly different in the two solutions. Conclusion The tested commercial mouthwash accelerates the release of Ni ion from the two nickel alloys. This phenomenon is more significant in the nickel-casted alloy than in the other alloy type.关键词
