Matrix metalloproteinases (MMPs) stimulate alveolar bone loss in chronic periodontitis.
To evaluate the salivary and gingival crevicular fluid (GCF) levels of MMP-8 in patients with moderate to severe chronic periodontitis.
42 participants were divided into two groups: a case group (21 patients with generalized moderate to severe chronic periodontitis) and a control group (21 healthy periodontal subjects). GCF and saliva samples were obtained from both groups. Salivary and GCF MMP-8 levels of each subject were detected using the ELISA method.
Mean±SD values of salivary MMP-8 levels of the control and case groups were 1.52 ± 0.65 ng/ml and 6.06 ± 1.18 ng/ml, respectively, and statistically significant difference was observed (p=0.0001). Also, mean±SD values of GCF MMP-8 levels of the control and case groups were 0.87 ± 0.26 ng/ml and 2.92 ± 0.64 ng/ml, respectively; which was statistically significant (p=0.0001).
Our results demonstrate an increased concentration of salivary and GCF levels of MMP-8 in the patient group.
基质金属蛋白酶（MMPs）可刺激慢性牙周炎中的牙槽骨丢失。
评估中重度慢性牙周炎患者的唾液和龈沟液（GCF）中 MMP-8 的水平。
将 42 名参与者分为两组：病例组（21 名患有广泛中重度慢性牙周炎的患者）和对照组（21 名健康牙周受试者）。从两组中获取 GCF 和唾液样本。使用 ELISA 法检测每位受试者的唾液和 GCF MMP-8 水平。
对照组和病例组的唾液 MMP-8 水平的平均值±标准差分别为 1.52 ± 0.65ng/ml 和 6.06 ± 1.18ng/ml，差异具有统计学意义（p=0.0001）。同样，对照组和病例组的 GCF MMP-8 水平的平均值±标准差分别为 0.87 ± 0.26ng/ml 和 2.92 ± 0.64ng/ml，差异具有统计学意义（p=0.0001）。
我们的结果表明，患者组的唾液和 GCF 中 MMP-8 的浓度升高。
