Evaluation of Effect of Melatonin on Hematological Parameters in Patients of Periodontitis

Introduction: Considering the immunity enhancing property of melatonin, a study on the evaluation of the effect of melatonin on the hematological parameters in patients suffering from Periodontitis.  Methods: This study was conducted in the Department of Periodontics, Rural Dental College, Loni. Patients of chronic Periodontitis, of age between 18 to 65 years of either gender ready to give informed consent to participate in the study were included. Postoperative patients, patients having night duties, drivers and those using heavy machinery, pregnant women, lactating mothers, patients with any clinically significant systemic disease and patients on any other drugs were excluded from the study. Patients were divided into two Groups. Group B received scaling and root planning (SRP) and melatonin 3 mg per day were compared to Group A which received SRP only. The Total Leukocyte count, Differential Leukocyte count and Erythrocyte sedimentation rate of each patient was studied at a baseline, 1^st (30 days) visit, 2^nd (60 days) visit and 3^rd (90 days) visit. Results: Both the groups consisted of 80 subjects each. Group A consisted of 71.25% male and 28.75% female patients. There were 56.25% male and 43.75% female patients in Group B. With respect to visit 3, the TLC was statistically lower in Group B. The neutrophil count of Group B was significantly lower during visit 3 as compared to Group A. The lymphocyte count of Group B was significantly lower than that of Group A during the visit 1, and also significantly higher during visit 3 on comparison with Group A. There was no statistically significant difference in the groups with respect to eosinophil and basophil count. The Monocyte count of Group B was statistically lower when compared to that of Group A. There was no statistically significant difference between ESR of Group A & Group B.  Conclusions: It can be concluded that melatonin has a positive effect on TLC and differential count of patients of periodontitis, conferring a new facet to the management of periodontitis and an attempt to impede the disease progression.
