The Porphyromonas gingivalis fimbriae level was examined in the gingival crevicular fluid (GCF) from adult human subjects using an immunoblot assay with a monoclonal antibody. The cytokines, interleukin-1 alpha (IL-1 alpha), IL-1 beta, IL-6 and tumor necrosis factor-alpha (TNF-alpha) levels in the GCF were quantified by enzyme-linked immunosorbent assay (ELISA). The reactivity of the GCF samples with the monoclonal antibody against P. gingivalis fimbriae was related to the IL-2 beta, IL-6 and TNF-alpha levels. Moreover, the fimbriae content was associated with the gingival index (GI). In contrast, no significant correlation was seen between the fimbriae content and IL-1 alpha level. These results suggest that there are possible associations between P. gingivalis fimbriae and IL-1 beta, IL-6 and TNF-alpha in the gingival crevicular fluid.
