Background: “Aggressive periodontitis (AgP) is a destructive disease characterized by the following: The involvement of multiple teeth with a distinctive pattern of periodontal tissue loss; a high rate of disease progression; an early age of onset; and the absence of systemic diseases.’’ Chronic low-level bacteremia and systemic inflammatory response have been suggested as a pathogenic link between periodontal disease and systemic disease. The present study was aimed to assess the levels of systemic inflammatory markers in patients with AgP. Methods: A sample of 50 systemically healthy patients comprised two groups, based on full mouth periodontal examination: Group I healthy individuals, includes 25 periodontally healthy subjects with fully functioning dentition. Group II includes 25 patients diagnosed clinically as AgP. Laboratory blood investigation included white blood cell (WBC) count, neutrophil count, lymphocyte count, and platelet count. Serum protein parameters included total protein (TP), albumin (ALB), and globulin (GLB). Periodontal clinical parameters including plaque index, gingival index, probing pocket depth, and clinical attachment level were recorded. Results: Data analysis shows an increase in WBC, neutrophil, lymphocyte, and platelet count and a decrease in TP, ALB, and GLB in AgP patients when compared to healthy individuals. Conclusion: Results of the present study shows an increase in blood parameters and decrease in serum protein parameters in AgP. Hence, AgP could be considered as one of the risk factors associated with the cardiovascular diseases as assessed by changes in the level of systemic inflammatory markers observed.

Background: Host response to periodontal disease includes the release of different enzymes from stromal, epithelial or inflammatory cells. The enzymes which are produced from these cells are associated with cell injury and cell death like: Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Alkaline phosphatase (ALP) and Blood urea nitrogen (BUN). Normal enzymatic activity of these enzymes is necessary for healthy functioning of gingiva and periodontium. The aim of the study is to estimate the levels of enzymes AST, ALT, ALP and BUN and to correlate the level of estimated enzymes with that of clinical parameters in the saliva of Healthy subjects, Gingivitis patients and patients with chronic periodontitis. Methods: The study included a total of 40 male subjects within the age group of 21 to 50 years, and examined the activity of enzymes AST, ALT, ALP and BUN in saliva spectrophotometrically and compared their values between healthy subjects, gingivitis and chronic periodontitis patients. Clinical parameters like OHI – S (Oral hygiene index - Simplified, SBI (Sulcus Bleeding Index), PPD (Probing Pocket Depth), CAL (Clinical Attachment Level), and PI (Periodontal Index) were recorded. Results: Obtained results showed statistically significant increases of activity of AST, ALT, ALP, and BUN in saliva from patients with periodontal disease (p
