Oral multi-niche microbiota and age stratification for precision screening of periodontitis in Chinese adults
This project provides 16S rRNA gene sequencing data of oral microbiota from saliva, dental plaque and tongue plaque of 120 Chinese adults aged 20-90 years, with participants divided into periodontitis high-risk and low-risk groups and further stratified by age. The dataset characterizes niche and age-related oral microbial heterogeneity associated with periodontitis, and offers foundational data for developing non-invasive microbiota-based diagnostic tools for periodontitis in community and primary healthcare settings.
