摘　　要：目的探讨镍铬合金烤瓷冠修复对牙周组织的影响。方法选择2005年9月至2006年4月在南京军区福州总医院476临床部口腔科采用镍铬合金烤瓷冠进行上颌切牙修复的19例患者,共23颗镍铬合金烤瓷冠修复的上颌切牙,以患牙对侧的同名健康牙为对照牙,在镍铬合金烤瓷冠戴入6~9个月后复诊,进行牙周临床检查,分别采集患牙及对照牙的龈沟液进行定量,并对龈沟液中的C-反应蛋白(CRP)和肿瘤坏死因子-α(TNF-α)进行检测。结果符合临床合格要求的镍铬合金烤瓷冠修复后,患牙的菌斑指数没有明显改变,但龈沟液量、探诊深度、龈沟内出血指数、龈沟液内CRP、TNF-α增高。结论镍铬合金烤瓷冠对患牙的牙周组织有一定的不良影响。Objective To detect the effects of Ni-Cr based porcelain-fused-to-metal(PFM)crown on the periodontal tissue.MethodsTwent-three maxillary incisors in 19 patients with Ni-Cr based PFM crowns were included in this study.The contralateral homonymy natural teeth were healthy and treated as control teeth.The patients were followed up 6 to 9 months after crowns placement.The gingival crevicular fluid(GCF)samples were collected and weighed.Then the clinical parameters such as plaque index(PLI)、probing depth(PD)and sulcus bleeding index(SBI)were recorded for the test and control groups.CRP and TNF-α levels of GCF were detected.ResultsAfter the placement of Ni-Cr based PFM which was clinically accepted,although the changes of and PL1 were insignificant,the concentration of CRP、TNF-α、PD 、SBI and GCF volume increased.ConclusionNi-Cr based PFM crowns clinically accepted have negative influences on periodontal tissue.
