Evaluation of Correlation Between Periodontitis and ABO Blood Grouping- A Clinical Study

Background: Periodontal disease comprises a heterogeneous group of infectious disease that lead to pathologic destruction of the periodontium. This disease affects the gingiva and cause gingival inflammation and with involving the supporting fibers and bone, the tooth becomes loose and finally the tooth is lost. The present study was conducted to determine whether there was a relationship between periodontal diseases and ABO blood groups. Materials and Methods: This study was conducted on 1000 subjects based on periodontal condition, blood group, and medical history. The subjects were divided into three groups as those with gingivitis, periodontitis, and the healthy ones. Results: Results showed that higher percentage of B group patients were found in both gingivitis group and periodontitis group. Conclusion: Author concluded that ABO blood subgroups and Rh factor may constitute a risk factor on the development of periodontal disease.
