目的：研究使用不同合金烤瓷冠修复后龈下菌斑中牙龈卟啉单胞菌的变化。方法：选择门诊患者行下颌第一磨牙全冠修复共60例，随机分入两组不同合金烤瓷冠组，分别在戴入前，戴入后1个月、3个月检查龈沟出血指数，并且采用荧光定量聚合酶链反应测定龈下菌斑中牙龈卟啉单胞菌的变化。结果：比较修复前，钯银合金组的龈沟出血指数在修复后1个月、3个月无明显升高（P＞0.05）；而钴铬合金组的龈沟出血指数在修复后1个月、3个月有较明显升高（P＜0.05）；与修复前比较，钯银合金组的牙龈卟啉单胞菌相对定量值在修复后1、3个月无明显增加（P＞0.05）；钴铬合金组在修复后1个月、3个月的牙龈卟啉单胞菌相对定量值有明显增加（P＜0.05）。结论：两种合金材料的烤瓷冠修复后对患者牙龈有一定的影响；其中钴铬合金影响明显大于钯银合金。

Objective To investigate the variation of P.gingivalis influenced by different alloy porclain crown. Methods A total of 60 patients,need restoration treatment of mandibular first molar by PFM crown,they were all randomly chosen to participate in two groups-sliver-palladium alloy porclain group or cobalt-chromium alloy porclain group that each one is 30 petients.We used Polymerace Chain Reaction to have quantitative determination for P.gingivalis,and check up the SBI before and after restoration one and three months. Results Compared with those before restoration.The SBI of one and three months after restoration in the cobalt-chromium alloy porclain group is higher(P<0.05)while in the sliver-palladium alloy porclain group is not changed(P>0.05).Also the same results turn out in the quantities of P.gingivalis after Poly-merace Chain Reaction. Conclusion PFM crowns may have some effects on variation of P.gingivalis.The sliver-palladium alloy porclain is better than the cobalt-chromium alloy porclain.So the sliver-palladium alloy is an ideal substrate material of PFM crown.
