Periodontitis-atherosclerosis syndrome: an expanded model of pathogenesis.
The early reports of a linkage between periodontitis and atherosclerosis have garnered further support by additional data generated by several investigative teams in many different countries. The evidence continues to suggest that periodontitis may be an important risk factor or risk indicator for cardiovascular pathology for some individuals. The term periodontitis-atherosclerosis syndrome (PAS) is proposed as a new diagnostic term to describe this condition in these individuals. Current evidence, albeit preliminary in nature, which describes a cluster of clinical signs and symptoms that are associated with this condition, is presented. It is clear that this syndrome will require considerable study and refinement before a definitive diagnosis and treatment plan can be formulated. Potential mechanisms by which systemic inflammation and infectious challenge of periodontal origin may serve as a potential modifier of cardiovascular disease are discussed in the context of a detailed working model of pathogenesis. This hypothetical model embraces many cellular and molecular components of atherogenesis and thromboembolic diseases from the perspective of periodontitis pathogenesis. Many aspects of the hypothetical model remain unproved; however, it is our opinion that only through the clarification of the mechanisms of pathogenesis can we ultimately construct a knowledge framework for accurate diagnoses and successful therapies. The concept of diagnosing and treating a periodontal patient to minimize the deleterious effects of this chronic infectious and inflammatory condition on the cardiovascular system represents an unprecedented challenge to our profession.
