NCT ID NCT07669233
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether certain amino acids in saliva differ between people with healthy gums, gingivitis, and periodontitis. Researchers also tracked how these amino acids changed after standard non-surgical gum treatment in 32 periodontitis patients. The goal is to see if saliva tests could help diagnose or monitor gum disease.
