Who could benefit from this research

Could help

Adults 21 years and older who are participants in All of Us, UK Biobank, Vanderbilt Biostatistics/All of Us subsets, and related biobanks with available saliva genomic and microbiome data.

Less likely to help

Individuals without access to these biobank datasets or who are not part of the included populations may not directly benefit.

What this research studies

Researchers will link host DNA data, saliva microbiome profiles, and electronic health records from multiple biobanks to study oral health. The project uses existing large datasets to explore how genetics may shape the oral microbiome and influence diseases such as dental caries and periodontitis. Findings could help identify people at higher risk and point toward personalized prevention strategies in the future.

Why it matters

Potential benefit: If successful, the work could lead to personalized risk assessment and prevention for oral diseases.

How similar studies have gone: Preliminary analyses show saliva-based genomics can reveal disease-associated microbial patterns; this project scales that approach to a population level.
