牙周非手术治疗对龈沟液MMP-8及其抑制剂TIMP-1水平的影响

目的: 比较慢性牙周炎患者非手术治疗前、后龈沟液MMP-8、TIMP-1水平的变化。方法: 选择慢性中重度牙周炎30例, 治疗前、后临床检查牙龈出血指数(SBI)、菌斑指数(PLI)、探诊深度(PD), 采集龈沟液, 采用双抗体夹心ABC-ELISA法检测MMP-8、TIMP-1的含量。采用SSPS 19.0软件包对数据进行配对样本t检验和多元相关分析。结果: 治疗后MMP-8、TIMP-1水平显著下降, MMP-8/TIMP-1 比率治疗前、后无显著差异。多元相关分析各变量间相关性, 发现MMP-8和龈沟液重量呈正相关关系。结论: 牙周非手术治疗能显著降低龈沟液MMP-8、TIMP-1水平, 从而减轻牙周组织损伤。

The influences of non-surgical periodontal treatment on gingival crevicular fluid levels of MMP-8 and tissue inhibitor of TIMP-1

PURPOSE: To compare the levels of MMP-8 and TIMP-1 in the gingival crevicular fluid (GCF)of chronic periodontitis(CP) patients before and after non-surgical periodontal therapy. METHODS: Sulcus bleeding index (SBI), plaque index (PLI) and probing depth (PD) were detected before and after therapy. GCF was collected from CP patients before and after therapy. MMP-8 and TIMP-1 were determined by enzyme-linked immunoabsorbent assay. The data was analyzed using paired-sample t test and multi-correlation analysis with SSPS 19.0 software package. RESULTS: The levels of MMP-8 and TIMP-1 decreased after therapy, and there was no significant difference in the MMP-8/TIMP-1 ratio. Correction analysis showed that a significant correction was found between MMP-8 and GCF weight. CONCLUSIONS: MMP-8 and TIMP-1 decrease after non-surgical periodontal therapy.
