| 摘 要： | 目的通过对不同材料的烤瓷冠修复后龈沟液（gingival crevicular fluid，GCF）内肿瘤坏死因子-α（tumor necrosis factor-α，TNF-α）水平的测定，探讨内冠材料对牙周的影响。方法选择临床病例24例，采用镍铬合金烤瓷冠和金铂合金烤瓷冠修复，分别在修复前、修复后6个月进行临床检查和取GCF，进行GCF量和TNF-α水平的测定。结果6个月时镍铬合金组与金铂合金组在指标上均有明显差异。结论非贵金属对牙周组织有不利影响。

| Abstract: | Objective： To investigate the effect of different inner crown materials on periodontal tissue by means of measuring the level of TNFα in gingival crevicular fluid（GCF） after PFM restoration.Methods： The anterior teeth of 24 patients selected by random were restored by Ni-Cr alloy PFM and Au-Pt alloy PFM.GCF was collected from labial and lingual of mesial site and distal site before the tooth preparation by filter paper.At the point of 6 month after cementation,GCF was collected at the same sites.The level of TNF-α was detected by enzyme-linked-immunoadsorbent assay（ELISA）method,and analyzed the variation between the pre-restoration and post-restoration.Results： Compared with pre-restoration,all indexes had significant difference between the Ni-Cr alloy group and the Au-Pt alloy group after 6 month.Conclusion： Non-noble metal has bad effect on the peirodontal tissue. |
