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。

Abstract: 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), 6 months 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 T1~3 in 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.
