• Status: Completed
• Trial end date: 2015-10-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this clinical study was to evaluate, the effectiveness and sensitivity post-treatment of a 6% hydrogen peroxide with nitrogen-doped titanium dioxide light activated bleaching agent, the impact of shorter interval times on tooth sensitivity and to compare the efficacy with 2 different application protocols. This is a clinical randomized double-blind split-mouth study. 31 patients were treated with: one upper hemi arcade with one application of 36 minutes and the other hemi arcade with 3 applications of 12 minutes each with a 6% hydrogen peroxide. Two sessions were appointed with 48h of intervals between them. Tooth colour was registered by VITA Classical amd VITA Bleach guide by two blinded assessors in the beginning, immediately after each session. Tooth colour variation and sensitivity were compared between both application protocols
