Periodontal Disease - Causes

(Page 2)

Studies suggest that this inflammatory response may have damaging effects not only in the gums but also in organs throughout the body, including the heart.

Viral Causes

Certain herpes viruses (herpes simplex and varicella-zoster virus, the cause of chickenpox and shingles) are known causes of gingivitis. A 2000 study found that other herpes viruses (cytomegalovirus and Epstein-Barr) may play a role in the onset or progression of some types of periodontal disease, including aggressive and severe chronic periodontal disease. All herpes viruses go through an active phase followed by a latent phase and possibly reactivation.

Some experts theorize that these viruses may cause periodontal disease in different ways, including release of tissue-destructive cytokines, overgrowth of periodontal bacteria, suppressing immune factors, and initiation of other disease processes that lead to cell death.
