NCT ID NCT07143370
First seen Nov 01, 2025 · Last updated Jun 16, 2026 · Updated 33 times
Summary
This study compared how much bacteria builds up on 3D printed clear aligners versus conventional ones. Thirty participants wore each type for a short time, and researchers swabbed their teeth and the inside of the aligners to measure microbial growth. The goal was to see if the material affects oral hygiene, not to treat any disease.
