The analysis of matrix metalloproteinase-8 in gingival crevicular fluid and periodontal diseases

Abstract Background Pathologically elevated levels of matrix metalloproteinase-8 (MMP-8) and Lactoferrin in oral fluids have been associated with the presence of gingivitis/periodontitis. This study aimed to assess the origin of MMP-8 and Lactoferrin in periodontitis patients and to identify the degree to which conventional clinical parameters correlate with their presence. Methods A total of ten periodontitis and ten healthy patients were included in this study. Whole saliva (stimulated and unstimulated), parotid/sublingual glandular fluid and gingival crevicular fluid from pockets and sulci were tested for MMP-8 and Lactoferrin and protein concentrations were quantified using an ELISA assay. Clinical parameters were checked for potential associations with MMP-8 and Lactoferrin levels. Results Periodontal patients presented higher concentrations of MMP-8 and Lactoferrin in pockets than other sources (P = 0.03). Lactoferrin measurement was higher in the parotid compared to sublingual glandular fluid in periodontitis patients (P = 0.03). Increased probing pocket depth was positively correlated with high MMP-8 and Lactoferrin levels. Conclusions Periodontal pockets appear to be the major source of active matrix metalloproteinase and Lactoferrin, which also may also enter the oral cavity through the salivary glands. Since clinically healthy sites in periodontitis patients also had elevated biomarker levels, gingival crevicular fluid biomarker testing may be more predictive of future tissue breakdown than conventional clinical parameters.

Aim. Cathepsin C is the activator of the polymorphonuclear leukocyte-derived proteinase 3, which contributes to inflammatory processes. The aim of the present study was to investigate gingival crevicular fluid (GCF) proteinase 3 and cathepsin C levels in periodontal diseases.Design. Eighteen patients with chronic periodontitis (CP), 20 patients with generalized aggressive periodontitis (G-AgP), 20 patients with gingivitis, and 18 healthy subjects were included in the study. Periodontal parameters including probing depth, clinical attachment level, papilla bleeding index, and plaque index were assessed in all study subjects. GCF proteinase 3 and cathepsin C levels were analyzed by ELISA.Results. GCF proteinase 3 total amount was significantly higher in diseased groups compared to control group, after adjusting ageP<0.05. No differences were found in GCF cathepsin C levels among the study groupsP>0.05. Periodontal parameters of sampling sites were positively correlated with GCF proteinase 3 total amountsP<0.01but not with cathepsin C total amountsP>0.05.Conclusions. Elevated levels of GCF proteinase 3 in CP, G-AgP, and gingivitis might suggest that proteinase 3 plays a role during inflammatory periodontal events in host response. However, cathepsin C in GCF does not seem to have an effect on the pathogenesis of periodontal diseases.

Technological Improvements

With the recent description of 12 different forms and sub-forms of periodontitis by the World Workshop in Clinical Periodontics (1989), increased emphasis has been placed on diagnosis. Dr. Ranney's review addressed the specificity and sensitivity of current diagnostic tests with respect to their ability to differentiate between health and disease and between the individual disease states. Although considerable microbiologic and immunologic data have been accumulated in the past decade, very little of this information has proved to be sufficiently sensitive to be of use in differential diagnosis. Clinical measurements provide us with an insensitive, retrospective analysis of what has already occurred but allow us to diagnose disease based on its natural history. Measures of attachment levels, by use of conventional probes, are only sufficiently sensitive indicators of periodontitis when as much as 20-30% of attachment has already been lost. Current technological improvements in probing measurements and radiographic assessment may increase sensitivity in this area. Future improvements in diagnostic techniques will occur with the advent of sensitive biochemical analyses of gingival crevicular fluid. These assays will provide a more objective analysis of inflammation and, in time, will provide sufficient sensitivity to allow for differentiation between and among the various forms of periodontal disease. Future directions in diagnosis will focus on the identification of disease-susceptible individuals and the prediction of future periodontal breakdown.
