The Relationship Between Periodontal Infection and Systemic and Distant Organ Disease in Dogs

Infection in the mouth causes systemic and distant organ changes in dogs. This article summarizes the information available. Reported changes include an increase in liver-generated acute-phase proteins in response to the infectious insult to the body and evidence of microscopic changes in renal, hepatic, and cardiac tissues. Treatment of periodontal infection results in a decrease in the acute-phase protein concentration, which supports the hypothesis that a cause-and-effect relationship exists between periodontal infection and distant organ changes.
