Salivary Microvesicle Methylome and Microbiome Profiles in Periodontitis: An Exploratory Study
Saliva-based biomarkers can now distinguish advanced gum disease with high accuracy, advancing liquid biopsy methods potentially applicable to oral and systemic diseases.
This exploratory study identified 1,196 differentially methylated regions in salivary microvesicle DNA that distinguish stage III/IV periodontitis from health and gingivitis with AUC>0.9, alongside microbiome profiles from bacterial outer membrane vesicles. While focused on periodontitis rather than malignancy, the study advances salivary liquid biopsy methodology with potential applicability to oral cancer and systemic disease detection.

Why it surfaced
Exploratory salivary liquid biopsy study — methodologically interesting for cfDNA methylomics application but not cancer detection per se; relevance to watchlist topic partially indirect. Small n=62.
