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
