IL‐12 and IL‐18 levels in serum and gingival tissue in aggressive and chronic periodontitis

Abstract

Our results showed higher levels of IL-12 in gingival tissue and serum of patients with aggressive periodontitis, and IL-18 was elevated in the serum of CP patients. The patterns of IL-12 and IL-18 are different in chronic and aggressive periodontitis; this finding suggests distinctive mechanisms of immunopathogenesis between these forms of periodontitis.
