Salivary Microbial Profiles Across Periodontal Severity Stages in a Mexican Population

A cross-sectional study of 133 adults from a systemically healthy Mexican population, classified into four periodontal health groups. The dataset contains salivary microbial profiles for 40 bacterial species, analyzed using Checkerboard DNA-DNA hybridization. It was authored by Paola E. García-Vázquez and last updated on 2026-04-30.

Use Cases

• Predicting periodontal disease severity based on salivary microbial abundance signatures.
• Identifying key bacterial species, such as Porphyromonas gingivalis and Tannerella forsythia, as biomarkers for disease progression.
• Training models to assess the relationship between clinical risk factors (age, dental biofilm) and microbial dysbiosis.
• Evaluating saliva as a diagnostic matrix for resource-limited clinical settings based on microbial profiles.

Strengths

• Data from 133 participants provides a foundation for statistical analysis.
• Microbial profiles for 40 bacterial species at the species level offer detailed taxonomic resolution.
• Participants are classified according to the standardized 2018 AAP/EFP periodontal disease classification.
• Analysis includes clinical and sociodemographic variables for risk factor modeling.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a specific Mexican population, which may limit generalizability to other demographics.
