【摘要】：目的探讨不同种金属烤瓷冠(PFM)对老年人基牙龈沟液(GCF)总量及碱性磷酸酶(ALP)水平的影响。方法把下颌单侧游离端缺失附着体义齿修复老年患者30例60颗基牙,按患者志愿选择的附着体基牙烤瓷冠金属材料不同随机分成镍铬合金(N)组、钴铬合金(G)组、金合金(J)组,以对侧同名牙作对照组(D),在修复前和修复后6个月检测基牙及对侧同名临床指标、GCF总量及GCF中ALP含量,做每组修复前后及组间临床指标、GCF总量及GCF中ALP的比较。结果修复前各组及对照组临床指标、GCF总量、ALP水平比较均无明显差异(P0.05),修复后各组临床指标、GCF总量及ALP水平均有升高,N组升高最多,J组升高最低,N组和G组与修复前及对照组比较均有显著差异(P0.05)。J组与修复前及对照组比较无明显差异(P0.05),三个实验组间比较均有明显差异(P0.05)。结论非贵金属烤瓷冠对基牙牙周组织的刺激程度明显高于贵金属烤瓷材料。
[Abstract]:Objective to investigate the effect of PFM on GCFCs and ALP levels in aged patients with gingival crevicular fluid (GCF). Methods A total of 30 cases (60 abutments) with unilateral free end attachment denture were randomly divided into three groups: Ni-Cr alloy (N) group, Cobalt-Chromium alloy (G) group, and gold alloy (J) group. The contralateral teeth with the same name were used as the control group. Before and 6 months after repair, the total amount of GCF-GCF and ALP content in GCF of abutment and contralateral homonym were measured, and the clinical indexes of GCF were compared before and after repair. Results there was no significant difference in the levels of ALP and GCF in each group and control group before and after repair (P 0.05). After repair, the total clinical index and the level of ALP were all increased in group N and group J with the lowest elevation in group N and group G in group G and repair. There was no significant difference between the former and the control group (P 0.05). There was no significant difference between group J and the control group (P 0.05), but there was a significant difference among the three experimental groups (P 0.05). Conclusion Non-precious metal porcelain crown can stimulate the periodontal tissue of abutment teeth more than that of precious metal porcelain.
