It has long been assumed that all chronic periodontitis is the same no matter where one lives in the world.  But some scientists have wondered whether the bacterial composition of the oral biofilm – the sticky, mat-like microbial communities that form on our teeth and cause chronic periodontitis – might vary geographically.  In the November issue of the Journal of Clinical Periodontology, NIDCR grantees and their colleagues report for the first time that this is indeed the case.  In a study of more than 300 patients with chronic periodontitis from Sweden, the United States, Brazil, and Chile, they found clear geographical differences in the bacterial content of dental plaque obtained from the periodontal lesions.  To hear more about this important paper, the Inside Scoop recently talked with lead author Anne Haffajee, B.D.S., and Sigmund Socransky, D.D.S., the senior author. Both are scientists at The Forsyth Institute in Boston.

There are over 600 species of periodontal biofilms that have been DNA sequenced. Over the last seven months, the Frequency Foundation has worked out detailed frequencies for over 50 of the most common ones. Some are based on the lyme borellia spirochete and cause elevated blood pressure. All can go systemic in the body and cause a wide variety of symptoms and disease outcomes. For the first time it is possible to work on getting rid of the root cause of gum disease. 

Frequencies are posted on the subscribers site.
