摘 要:目的:探讨3种不同材料的全冠修复体对基牙龈沟液(GCF)中的天冬氨酸转氨酶(AST)和碱性磷酸酶(ALP)水平的影响。方法:选择临床病例30例,分为3组,分别采用钴铬合金烤瓷冠、纯钛烤瓷冠、全瓷冠修复。在修复前、修复后1、3、6个月分别进行GCF量和AST、ALP总量的测定及分析。结果:修复前及修复后1个月时,3组之间各检测指标无明显差异;修复后3、6个月时钴铬合金烤瓷冠组的GCF、AST、ALP值均高于纯钛烤瓷冠和全瓷冠组;而纯钛烤瓷冠组与全瓷组的GCF、AST、ALP值无显著变化且2组之间各项指标无明显差异。结论:临床合格的钴铬合金烤瓷冠可导致GCF量及其成分变化,对牙周组织有一定的不利影响,而纯钛烤瓷冠和全瓷冠对牙周组织健康的影响相对较小。Objective:To further investigate the effects of three kinds of material on the level of aspartate aminotransferase (AST) and alkaline phosphatase (ALP) in gingival crevicular fluid (GCF). Methods: The anterior teeth and the premolar teeth of 30 patients were divided into three groups randomly fur Co-Cr alloy PFM, Ti PFM and all ceramic crown. Before tooth preparation, 1, 3 and 6 months after cenlentation, GCF was collected at the same sites. The levels of AST and ALP were detected by automated chemical analyzer, and analyzed the variation hetween the pro-restoration and post-restoration. Resuits:Betore tooth preparation and 1 month after cementation, all indexes showed no difterencc among three groups. The level of GCF, AST and ALP of Co-Cr alloy group showed conspicuous difference with Ti PFM and all ceramic crowns after 3 months and 6 months, ftowever, the levels of GCF, AST and ALP of Ti PFM group showed no dift)rence with all ceramic crowns. Conclusion:Co-Cr based PFM crowns which clinically accepted have lead to changes of the levels of GCF, AST and ALP. Co-Cr based PFM crowns have negative intluenees on periodontal tissue. The Ti PFM and all ceramic crown may affect periodontium less than the Co-Cr PFM in observation period of this study.
