NCT ID NCT05211843

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at whether measuring insulin in saliva can help identify children at risk for metabolic problems and cavities. Researchers gave 105 children aged 5-10 either water, apple juice, or nothing, and checked how their saliva insulin changed. The goal was to see if saliva insulin could be a simple, non-invasive tool for school-based health screenings.
