镍铬、金合金烤瓷牙修复后不同时期龈沟液IL-8含量水平探讨

摘要

Objective To investigate the effect of gold alloy and Ni Cr porcelain dental restoration on periodontal tissue. Methods in our hospital in 2011 during the May 5 to June 2012 80 cases of anterior teeth defect patients. According to the dif-ferent crown materials within the repair will be the group of gold alloy, Ni Cr alloy was observed in different periods of aspartate aminotransferase (AST) and IL-8 levels, gingival crevicular fluid amount (GCF), phosphorus, alkaline acid (ALP). Results after treatment, 1 weeks, two kinds of alloy porcelain compared with the previous repair in gingival crevicular fluid volume, to-tal IL-8, with statistical significance;3, 6 months after the repair, the gold alloy group the index decreased significantly, to 6 months and gradually returned to the level before the repair. Ni Cr alloy group the index at 6 months in the repair and restoration of the former comparison was statistically significant, gold alloy group in the repair of the 3 and 6 months, the index was signifi-cantly lower than that of Ni Cr alloy group, the difference was significant;the content of IL-8, two kinds of alloy porcelain only significant differences in the repair of 3 months, repair at 6 months, two kinds of metal ceramic were restored to the level before the repair;Ni Cr alloy group repair at 6 months of AST, ALP and repair before there was significant difference, and gold The AST level was significantly increased in the alloy group at 6 months, and the difference was not significant between the gold al-loy group and the healthy teeth at 6 months after the repair of the ALP. Conclusion the irritation of the gold alloy to the gums is small, and it is an ideal material for the porcelain fused to metal crown.%目的：探讨金合金、镍铬烤瓷牙修复对牙周组织的影响。方法：选取我院2011年5月～2012年5月期间的80例前牙缺损患者，根据修复内冠材料不同将其分为金合金组、镍铬合金组，观察不同时期天冬氨酸转氨酶（AST）、IL-8水平、龈沟液量（GCF）、碱性磷酸（ALP）。结果：修复后1周，两种合金烤瓷在龈沟液量、IL-8总量上与修复前比较，具有统计学意义；修复后3、6个月时，金合金组上述指标明显下降，至6个月时逐渐恢复至修复前水平，而镍铬合金组上述指标在修复6个月时与修复前比较，具有统计学意义，金合金组在修复3、6个月时，上述指标明显低于镍铬合金组；在IL-8含量上，两种合金烤瓷仅在修复3个月时有统计学差异，修复6个月时，两种金属烤瓷均恢复至修复前水平；镍铬合金组修复6个月时AST、ALP与修复前比较均存在明显差异，而金合金组在修复6个月时，AST水平也比修复前显著提高，在ALP上，修复6个月时，金合金组与健康牙差异不大。结论：金合金对牙龈的刺激较小，是烤瓷压内冠的理想材料。
