Abstract
- Kraft-Neumärker M, Lorenz K, Koch R, Hoffmann T, Mäntylä P, Sorsa T, Netuschil L. Full-mouth profile of active MMP-8 in periodontitis patients. J Periodont Res 2012; 47: 121-128. © 2011 John Wiley & Sons A/S Background and Objective: MMP-8 in gingival crevicular fluid is considered as a protease with high destructive potential because of its ability to degrade collagen in periodontitis-affected patients. The aim of this study was to investigate whether there was a relationship between clinical diagnostic parameters and the concentration of active MMP-8 (aMMP-8) in gingival crevicular fluid in a site-level full-mouth analysis. Based on these data, the prognostic value of aMMP-8 levels in relation to pocket depth may be evaluated. Material and Methods: Clinical measurements of pocket depth, bleeding on probing (BOP), plaque index (PlI) and gingival index (GI), as well as samples of gingival crevicular fluid, were obtained from four sites of each tooth of nine healthy female patients with chronic generalized periodontitis. The aMMP-8 concentration in gingival crevicular fluid was quantified by ELISA using specific monoclonal antibodies. Multiple linear regression models for the single measures of aMMP-8 and pocket depth were calculated with GI and BOP as additional variables. Results: Between 92 and 112 recordings were obtained for each parameter in each patient. Mean values of between 31.5 and 88.8% were calculated for pocket depths of ≥ 4 mm. Mean pocket depths ranged from 3.11 to 4.73 mm, the mean BOP values ranged from 34.0 to 96.7% and the mean full-mouth gingival crevicular fluid aMMP-8 concentration ranged from 3.2 to 23.7 ng/mL. Conclusion: In this sample of female periodontitis patients, a broad range of intra-individual and interindividual aMMP-8 values was found. Although the explained variance was rather weak, a statistically significant relationship between aMMP-8 and pocket depth was proven. [ABSTRACT FROM AUTHOR]
