摘要(Abstract)：

目的:研究非贵金属烤瓷全冠对牙周组织所造成的影响。方法:经过特殊设计,造成实验性牙龈炎,在192个位点上作了0~6月时间的纵向观察,分别于戴冠后0、1、3、6月分别检测不同位点上共670个部位的龈沟液(GCF)中的天冬氨酸转胺酶(AST)水平记录牙周指标菌斑指数(PLI)、牙周探诊深度(PD)、龈沟出血指数(SBI)的变化。结果:GCF中的AST位点活性随着牙周组织的不断破坏加剧而呈逐步上升的趋势,PLI、PD、SBI也相应发生加重的变化。结论:非贵金属烤瓷冠边缘对牙周组织有一定的刺激作用,会形成牙龈炎等牙周病变,GCF中的AST表达水平与牙龈炎有密切的关系,检测GCF中的AST含量可作为了解牙龈炎严重程度的参考指标。
Objective: To study the effect of base metal ceramic crown on beagle canine tooth and its periodontium.Methods: Experimental gingival inflammation was made up artificially and following-up observation on it was carried out at 192 sites for 0～6 months.Aspartate aminotransferase(AST) levels in gingival crevicular fluid(GCF) at up to 670 positions were detected to see the developmental changes,in 0 month,1 month,3 months and 6 months after putting on porcelain crown.The periodontium indexes including plaque index(PLI),periodontial depth(PD),and sulcus bleeding index(SBI) were recorded simultaneously,and the changes were analyzed.Results: AST activity in GCF gradually increased following the intensification of destroy in periodontium.PLI,PD,and SBI correspondingly aggravatedly changed too.Conclusions: The margin of base metal ceramic crown has some irritative effect to periodontium and can cause cementopathia such as gingivitis etc.Since AST level in GCF is closely related with the severity of gingivitis,it can be used as reference index to show the severe degree of gingivitis.
