Saliva test may spot gum disease early

This study looked at three proteins in saliva—IL-6, IL-8, and LIGHT—to see if they can tell the difference between healthy gums, gingivitis (mild gum inflammation), and periodontitis (serious gum disease). Researchers measured these proteins in 60 non-smoking, healthy adults (20 with healthy gums, 20 with gingivitis, and 20 with periodontitis). The goal was to find out if these proteins could be used as a simple, non-invasive diagnostic tool for gum disease.
