Importance of MMP-8 in Salivary and Gingival Crevicular Fluids of Periodontitis Patients.

Background: Matrix metalloproteinases (MMPs) stimulate alveolar bone loss in chronic periodontitis.

Objective: To evaluate the salivary and gingival crevicular fluid (GCF) levels of MMP-8 in patients with moderate to severe chronic periodontitis.

Methods: 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).
