Multi‐Omics Signatures of Periodontitis and Periodontal Therapy on the Oral and Gut Microbiome

Journal of Periodontal Research, EarlyView.
This multi‐omics study integrates shotgun metagenomics and NMR metabolomics to reveal coordinated microbial and metabolic signatures of periodontitis across the oral–gut axis. Non‐surgical periodontal therapy partially restored ecological and functional balance, supporting oral health as a modifiable driver of systemic microbial homeostasis.
