Context: Anaemia and chronic periodontitis are among the most common diseases worldwide. Various studies since 20th century suggested conflicting reports regarding association between anaemia and chronic periodontitis. Aims: To evaluate the association between anaemia in patients with and without chronic periodontitisin Indian population. Settings and Design: We conducted a study where we compared haematological parameters of anaemia like number of erythrocytes, mean corpuscular volume, haemoglobin concentration, haematocrit, mean corpuscular haemoglobin, and mean corpuscular haemoglobin concentration in periodontally healthy subjects with chronic periodontitis patients. Methods and Material: In this cross-sectional study, 60 systemically healthy male subjects participated and patients with chronic periodontitis were included in study group and periodontally healthy subjects in control group. Periodontal parameters such as Plaque Index, Gingival Index, Gingival Bleeding Index, Periodontal Probing Depth and Clinical Attachment Loss were assessed in all participants. Radiograph was taken to confirm clinical diagnosis. Venous blood sample of 5ml were collected and sent for complete haemogram. Inter-group comparison done for clinical parameters of periodontitis and haematological parameters of anaemia. Statistical analysis used: Unpaired t test. Results: Periodontal parameters were significantly higher in study group in comparison with control group (p<0.05) but haematological parameters showed no significant difference between two groups (p>0.05) in the present study. Conclusions: Within the limits of this cross sectional study we conclude that blood parameters of anaemia are not affected by presence or absence of chronic periodontitis. This conflicting association must be further evaluated in long term study to validate any report.
