Effect of Scaling and Root Planing on Erythrocyte Count, Hemoglobin and Hematocrit in Patients with Chronic Periodontal Disease

Abstract

Purpose: Anemia of chronic disease, a cytokine–mediated anemia, is a frequent complication of many chronic inflammatory conditions. The present clinical trial was aimed to evaluate the effect of chronic periodontal disease on erythrocyte count, hemoglobin and hematocrit and the changes produced in these parameters after the provision of periodontal therapy.

Methods: 40 systemically healthy non–smoker male subjects in the age group of 25 to 50 years suffering with chronic periodontal disease were selected and categorized into 2 groups. Group A was categorized as chronic generalized gingivitis, and Group B was categorized as chronic generalized periodontitis on the basis of clinical findings. The clinical parameters Gingival Index (GI), Probing Pocket Depth (PPD) and Relative Attachment Level (RAL) and laboratory blood investigations viz erythrocyte count (EC), hemoglobin (Hb), hematocrit (HCT) and red cell indices (MCV, MCH, MCHC) were recorded at baseline. Complete oral prophylaxis was performed for all patients. Patients were recalled after 3 weeks and 3 months. The clinical and hematological parameters were re–evaluated to analyze the changes after provision of phase I therapy.

Results: The mean values of EC, Hb and HCT were significantly lower in Group B in comparison to Group A, and showed a significantly greater increase at 3 months of observation. However, the values of MCV, MCH and MCHC showed a non significant change during the same observation period in both the groups.

Conclusion: Lower values of EC, Hb and HCT in Group B showed that mild anemia is associated with chronic generalized periodontitis, which tends to improve after provision of periodontal therapy. Minimal changes in MCV, MCH and MCHC indicated that the lower values are not due to any vitamin and mineral deficiencies, but secondary to the chronic inflammatory changes associated with chronic periodontal disease.
