NCT ID NCT06782087
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests two methods to boost tooth bleaching for people with discolored, non-vital (dead) front teeth. One method uses a diode laser, the other a nano-chitosan gel, both applied with a standard bleaching agent. The goal is to see which approach whitens teeth more effectively over one month. The trial involves 42 adults with previously root-treated upper incisors.
