摘要：

目的 评价贵金属烤瓷全冠修复体对患牙牙周组织的影响。方法 选择2007年4月至2008年12月于沈阳市沈河区牙病防治所行贵金属烤瓷全冠修复的患者25例（患牙77颗），于修复前和修复后6、12个月分别进行常规龈沟出血指数（SBI）检查、龈沟液（GCF）称量及GCF中白细胞介素-1β（IL-1β）和肿瘤坏死因子-α（TNF-α）检测。结果 肩台设计为龈下的前牙SBI在修复后12个月与修复前比较差异有统计学意义（P < 0.05）， GCF质量及GCF中IL-1β和TNF-α含量在修复前与修复后6个月、12个月比较差异无统计学意义（P > 0.05）;肩台设计为龈上的磨牙SBI、GCF质量及GCF中IL-1β和TNF-α含量在修复前与修复后6个月、12个月比较差异无统计学意义（P > 0.05）。结论 贵金属烤瓷全冠修复体对患牙的牙周组织影响较小，有利于牙周健康。

Abstract:

Objective To detect the effect of noble-PFM on periodontal tissue of the restored teeth. Methods Seventy-seven teeth with noble-PFM of twenty-five patients were involved in the study. The patients were examined 6 and 12 months after the placement of the noble-PFM. The gingival crevicular fluid（GCF）sample was 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 significant differences in the SBI after placeing the crowns for 12 months（P < 0.05）;there were no significant differences in the weight of GCF and the levels of IL-1β and TNF-α after placeing the crowns（P > 0.05）. In posterior teeth group，the weight of GCF，SBI and the levels of IL-1β and TNF-α were of no significant differences（P > 0.05）. Conclusion Patients with noble-PFM have no apparently negative influences on gingival health of the restored teeth.
