WHERE IT ALL STARTEDWHERE IT ALL STARTED
• MATTILA & OTHERS (1989)– First to link dental health and the heart– Myocardial infarction patients– Caries, Periodontal Disease, or both?– Classic risk factors?
• MATTILA (1993)– Pathogenic mechanism

THANK YOU DR CHOW!THANK YOU DR CHOW!
• JADA EDITORIAL (1998)– “Research has identified periodontal disease as
a major risk factor for cardiovascular disease and stroke.”
– “Practitioners, get ready!”
• DR CHOW– “I really want to know more.”

PATHOGENISIS REVIEWPATHOGENISIS REVIEW
• Pathogenesis is still hypothetical
• Bacteria produce destructive toxins– gram negative = lipopolysaccharide– gram positive = mucopeptide complex
• Toxins attract White Blood Cells
• Accumulation is inflammation
• Inflammation is destructive as well

PERIODONTIUMPERIODONTIUM
• The soft tissue is in intimate contact with the tooth and plaque.
• The junctional epithelium is non-keratinized with exposed intercellular spaces.
• The tissue is highly vascularized and plaque products have access to it.
![Page 7: Cardiac Imp Of Perio Ds](https://reader033.vdocuments.mx/reader033/viewer/2022060118/558c6d3dd8b42a82298b463c/html5/thumbnails/7.jpg)
PERIODONTIUMPERIODONTIUM
• The plaque products provoke increased permeability and exudation.
• Inflammatory components and mediators are present in the gingival crevicular fluid.
• Periodontal disease appears to involve preferential diffusion through the junctional epithelium.
