Introduction: Alanine Aminopeptidase (ALAP) and dipeptidylpeptidase (DPP IV) are proteolytic enzymes released in the periodontal tissues from leukocytes, host cells and microorganisms. Both enzymes play an important role in collagen degradation and destruction of periodontal tissues. Therefore, detection of these enzymes might be useful in the diagnosis of periodontal disease. Aim: To assess the salivary levels of ALAP and DPP IV in periodontally healthy and those with chronic Periodontitis and to correlate the enzyme levels with the severity of disease. A prospective comparative case control study was done on 60 systemically healthy patients in the age group of 25-55 and was divided into four groups with 15 patients in each as Periodontally healthy, Mild, Moderate and Severe Periodontitis. Methodology: Parameters like Plaque index, Gingival bleeding index, Probing pocket depth and clinical attachment loss were recorded at baseline and unstimulated whole saliva was collected from each patient and quantified for levels of ALAP and DPP IV using spectroscopic quantification method. Statistical analysis used ANOVA, Students t test and Pearsons correlation coefficient analysis was used. Results: The salivary levels of ALAP and DPP IV were found to be higher in patients with Periodontitis than p healthy controls and were higher in severe (42.34±8.96) (8.41±1.44) and moderate group) (25.46±6.79) (5.17±1.31) than mild Periodontitis group) (15.83±4.54) (3.69±1.00) which was statistically significant. Discussion and Conclusion: ALAP and DPP IV were higher in saliva of patients with chronic Periodontitis and positive correlation existed between the levels of these enzymes with the severity of Periodontitis.
