The role of the Delta Neutrophil Index (DNI) in the pathogenesis and follow-up of periodontal disease has not been comprehensively documented. The study included 70 systemically healthy individuals, as a test group of 35 patients with Stage 3, Grade A periodontitis and a control group of 35 individuals with no periodontal disease. Blood samples were taken for the examination of DNI, white blood cells (WBC), immature granulocytes (IG), procalcitonin, C-reactive protein (CRP), lymphocyte count and neutrophil count. For the patients with periodontitis, blood sample assays were repeated 3 months after NSPT.
