Introduction: Peripheral artery diseases (PAD) and chronic periodontitis share common pathophysiology of chronic inflammatory diseases. Periodontal pathogens may play a role in the development and progression of atherosclerosis leading to vascular disease.So the present study was aimed to identify periodontal pathogens in atheromatous plaque  and in sub–gingival plaque in patients with PAD .

Methodology : 30 patients with PAD were divided into Group A(15): PAD with healthy periodontium and Group B(15): PAD with chronic periodontitis. Subgingival plaque and atheromatous plaque samples were collected and subjected to Polymerase chain reaction analysis for the presence of pathogens.

Results :Group B samples reported higher levels of  P.gingivalis (60%) in sub gingival samples and (46.7%) in atheromatous plaque .

Conclusion : Higher counts of P.gingivalis were reported in patients with chronic peridontitis and PAD thereby supporting the association between chronic periodontitis and PAD.
