Salivary Flow Rates and Xerostomia Measurements Across Seasons

A longitudinal observational study collected data from 39 healthy young men to assess factors influencing salivary flow and subjective oral dryness. Measurements include unstimulated and stimulated salivary flow rates, salivary cortisol and chromogranin A concentrations, urine specific gravity, room temperature, and relative humidity. The dataset was created by Kayoko Ito and last updated in May 2026.

Use Cases

• Modeling the relationship between unstimulated salivary flow and room temperature based on the significant association reported.
• Analyzing the impact of hydration status on salivary flow using urine specific gravity measurements.
• Investigating the link between psychological stress biomarkers (chromogranin A, cortisol) and xerostomia.
• Studying seasonal variations in salivary gland function by integrating temperature and humidity data.

Strengths

• Dataset includes multiple physiological and environmental measurements per participant, enabling multivariate analysis.
• Longitudinal design allows for observing changes over time within subjects.
• Clear statistical results are reported in the description, such as a p-value < 0.001 for chromogranin A association.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 5.5 KB, indicating limited scope.
