The American Academy of Periodontology estimates that 64.7-million Americans suffer from an advanced form of periodontal disease. In an effort to reduce that number the SIU School of Dental Medicine is taking part in a nationwide study entitled "Biomarkers of Periodontal Disease Progression".  Dr. Nathalia Garcia, a periodontist at the SIU SDM says they are currently seeking volunteers to participate in the study.

Applicants must be at least 25 years old, have at least 20 natural teeth, not counting wisdom teeth and be tobacco free for at least a year.

Dr. Garcia explains how the study will work.
