This study evaluates the effectiveness of different lasers in enhancing dental bleaching with hydrogen peroxide.
In vitro study using 100 enamel samples from 50 human premolars, divided into five groups.
Evaluation of tooth shade pre- and post-bleaching using a spectrophotometer and calculating Whiteness Index (∆WIᴅ) values.
One-way ANOVA and Bonferroni's post-hoc used to analyze differences between groups.
All bleaching systems showed significant differences (p < 0.001) in whitening efficacy.
Hypothetical whitening results: 940 nm diode laser (18.13 ± 4.57), Er:YAG laser (14.76 ± 6.11), 450 nm diode laser (8.56 ± 7.56), 980 nm diode laser (6.74 ± 6.48), control (4.25 ± 4.67).
