Article Synopsis
- The study investigates the effectiveness of different tooth bleaching techniques, comparing violet LED light to the traditional 35% hydrogen peroxide (HP) gel.
- It involves six techniques tested on pigmented bovine teeth, assessing color change and enamel surface integrity using spectrophotometry and scanning electron microscopy.
- Results indicate that shorter exposure times or using violet LED light alone can achieve similar whitening effects to HP treatments without damaging the dental structure.
This clinical study evaluated the effect of bleaching performed with violet LED light (405-410 nm), either combined with hydrogen peroxide (HP) gel, or not, on color change, dental sensitivity, participants' satisfaction and impact on their quality of life. A hundred participants were divided into one of the groups (n = 25): G1 - 35% HP (4 sessions, 1x/week); G2 - violet LED (4 sessions, 1x/week); G3 - violet LED (4 sessions, 2x/week); G4 - hybrid technique (violet LED + 35% HP; 4 sessions, 1x/week). Color evaluation was performed with colorimetric tests (objective and subjective), before, 14 days and 3 months after completion.
