Tooth analysis may reveal environmental clues to Crohn's disease
NCT ID NCT03706196
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This study looked at teeth from 14 adults living in areas with high or low rates of Crohn's disease. Researchers measured metals and other environmental chemicals in the teeth to see if differences might help explain why some areas have more Crohn's disease. The goal was to gather clues, not to test a treatment.
