Aim Periodontitis is a chronic inflammatory disease, characterized by irreversible destruction of tooth‐supporting tissue including alveolar bone. We recently reported mucin 4 ( MUC 4) and matrix metalloproteinase 7 ( MMP 7) as highly associated with periodontitis in gingival tissue biopsies. The aim of this study was to further investigate the levels of MUC 4 and MMP 7 in saliva and gingival crevicular fluid ( GCF ) samples of patients with periodontitis. Materials and Methods Saliva and GCF samples were collected from periodontitis patients and healthy controls. The levels of MUC 4, MMP 7, and total protein concentrations were analysed using ELISA or Bradford assay. Results MUC 4 levels were significantly lower in saliva and GCF from periodontitis patients relative to healthy controls. MMP 7 levels were significantly higher in saliva and GCF from periodontitis patients. Multivariate analysis revealed that MUC 4 was significantly associated with periodontitis after adjusting for age and smoking habits and, moreover, that the combination of MUC 4 and MMP 7 accurately discriminated periodontitis from healthy controls. Conclusions MUC 4 and MMP 7 may be utilized as possible novel biomarkers for periodontitis.
