摘要：

目的 探讨钴铬合金烤瓷全冠修复对患牙牙周组织的影响。方法 选择2007年4月至2008年10月来沈阳市沈河区牙病防治所应用钴铬合金烤瓷全冠修复的患者39例（106颗患牙），修复前和修复后6、12个月分别进行常规龈沟出血指数（SBI）检查，龈沟液（GCF）称量，GCF中白细胞介素-1β（IL-1β）和肿瘤坏死因子-α（TNF-α）质量浓度的检测。结果 修复前牙的患者患牙SBI、GCF质量、GCF中IL-1β和TNF-α的质量浓度修复前与修复后6个月比较差异无统计学意义（P > 0.05），与修复后12个月比较差异有统计学意义（P < 0.05）;修复后牙的患者患牙SBI、GCF质量修复前与修复后6个月比较差异无统计学意义（P > 0.05），与修复后12个月比较差异有统计学意义（P < 0.05）;修复后牙的患者患牙GCF中IL-1β和TNF-α的质量浓度修复前与修复后6个月和修复后12个月比较差异均无统计学意义（P > 0.05）。结论 采用钴铬合金烤瓷全冠修复前牙，修复时间超过12个月时，对SBI、GCF质量和GCF中IL-1β和TNF-α的质量浓度有显著影响;修复后牙，修复时间超过12个月时，对SBI、GCF质量有显著影响，而对GCF中IL-1β和TNF-α的质量浓度无明显影响。

Abstract:

Objective To detect the effect of Co-Cr PFM on periodontal tissue of the restored teeth with. Methods One hundred and six teeth with Co-Cr PFM of thirty-nine patients were involved in the study. The patients were examined before，6 and 12 months after，the placement of the Co-Cr PFM.The gingival crevicular fluid（GCF） sample were collected by filter paper strips. The weight of GCF and the concentration of GCF IL-1β and GCF TNF-α were detected.Then the following clinical parameters were recorded for the sulcus bleeding index（SBI）. Results In front teeth group，there were no significant differences in the weight of GCF ， SBI and the levels of IL-1β and TNF-α after placement of crowns at the 6th month（P < 0.05）， but there were significant differences in the weight of GCF ， SBI and the levels of IL-1β and TNF-α after placement of crowns at the 12th month（P < 0.05）. In posterior teeth group，there were no significant differences in the weight of GCF and SBI after placement of crowns at the 6th month（P > 0.05）， there were significant differences in the weight of GCF and SBI after placement of crowns at the 12th month（P < 0.05）.In both groups， there were no significant differences in the levels of IL-1β and TNF-α after placement of crowns（P > 0.05）. Conclusion Co-Cr PFM in front teeth has influence on the weight of GCF， SBI and levels of IL-1β and TNF-α in GCF after 12 months. Co-Cr PFM in posterior teeth has influence on the weight of GCF and SBI after 12 months， but doesn’t have influence on the levels of IL-1β and TNF-α in GCF after 12 months.
