摘　　要：目的：探讨氧化锆全瓷和钴铬合金冠修复对基牙牙周指数及致病菌的影响。方法：142例行全冠修复患者随机分为氧化锆组和钴铬合金组,分别于修复前（T0）、修复后6月（T1）、修复后12月（T2）和修复后24月（T3）时,记录患者牙龈颜色、牙龈出血指数（BI）、牙周探诊深度（PD）和菌斑指数（PLI）,利用PCR技术对龈下菌斑标本中伴放线嗜血杆菌（Aa）、具核酸杆菌（Fn）、牙龈卟啉单胞菌（Pg）、中间普氏菌（Pi）、福赛斯坦纳菌（Tf）和齿垢密螺旋体（Td）进行检测。结果：与T0相比,两组患者T1~3时BI和PD均增加,氧化锆组患者T1~3时BI和PD均小于钴铬合金组,差异均有统计学意义（P〈0.05）;修复后12个月时,氧化锆组患者龈下菌斑标本致病菌Aa、Fn、Pg、Tf和Td检出率均低于钴铬合金组,差异均有统计学意义（P〈0.05）。结论：相比于钴铬合金全冠修复,氧化锆全瓷全冠修复对患者牙周影响较小,且龈下菌斑中致病菌检出率较低。Objective：To investigate the effect of zirconia crowns and cobalt-chromium alloy crown restoration on abutment periodontal index and pathogens.Methods：One hundred and forty-two cases of total crown restoration patients were randomly divided into Zirconia group（n=75）and Cobalt-chromium alloy group,respectively（n=67）.At different time points：before restoration（T0）,6months after restoration（T1）,12 months after restoration（T2）and 24 months after restoration（T3）,the gingival color,gingival bleeding index（BI）,probing depth（PD）and plaque index（PLI）were recorded.H.actinomycetemcomitans（Ha）,Fusobacterium（Fn）,Porphyromonas gingivalis aeromonas（Pg）,Prevotella intermedia（Pi）,Tannerella forsythensis（Tf）and Treponema denticola（Td）in subgingival plaque samples were detected using polymerase chain reaction（PCR）method.Results：Compared with T0,BI and PD were increased at T1~3in both groups,BI and PD in Zirconia group were significantly less than those in Cobalt-chromium alloy group at T1~3（P〈0.05）.Twelve months after restoration,the detection rates of Aa,Fn,Pg,Tf and Td in subgingival plaque samples in Zirconia group were significantly lower than those in Cobalt-chromium alloy group（P〈0.05）.Conclusion：Compared with cobalt-chromium alloy restoration,zirconia crown restoration is beneficial to abutment periodontal index and pathogens.
