The goal of this clinical study was to evaluate whether non-surgical treatment for severe periodontitis (gum disease) could improve body-wide inflammation and blood fat levels in young adults with severe periodontitis. The main questions it aimed to answer were: Did non-surgical periodontal treatment improve gum health in young adults with severe periodontitis? Did non-surgical periodontal treatment change body-wide inflammation and blood fat levels after treatment? Researchers compared participants with severe periodontitis to healthy participants without periodontitis. Participants with severe periodontitis: * Received oral hygiene instructions, deep cleaning below the gumline, root surface cleaning, and removal of teeth that could not be saved * Had full-mouth gum examinations * Provided blood samples at the start of the study and again at 2 and 6 months after treatment Healthy participants: * Had gum examinations * Provided blood samples for comparison at the start of the study

Non-surgical periodontal treatment consisted of oral hygiene instruction, subgingival scaling, root planing, and extraction of unsalvageable teeth under local anesthesia. Treatment was completed within 1 week. Clinical periodontal measurements and blood samples were obtained at baseline and repeated at 2 and 6 months after completion of treatment.
