OBJECTIVE: This study aimed to investigate the difference in salivary protease expression in patients with chronic periodontitis and normal individuals.
METHODS: The stimulating saliva in patients with chronic periodontitis and normal individuals were collected. Protein chip technology was adapted to analyze salivary protease spectrum.
RESULTS: Among the 34 proteases in the chip, disintegrin and metalloproteinase (ADAM)8, matrix metalloproteinase (MMP)-8, MMP-12, neprilysin/CD10, and uridylyl phosphate adenosine/urokinase showed a significantly increased concentration in the saliva of chronic periodontitis patients compared with those in the saliva of normal individuals (P<0.01). By contrast, the concentrations of ADAM9, a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS)1, ADAMTS13, cathepsin B, E, L, V, X/Z/P, kallikrein 6, 7, 11, 13, MMP-9, proteinase 3, presenilin-1, and proprotein convertase 9 sharply decreased (P<0.05).
CONCLUSIONS: The results demonstrated that protease spectrum in the saliva of chronic periodontitis patients and normal individuals significantly differed. Analysis of salivary protease spectrum is a potential clinical method to examine, diagnose, and monitor chronic periodontitis.
