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.
