About

To evaluate the efficacy, safety and impact on quality of life related to oral health of home and office tooth whitening techniques in young individuals.

Full description

The aim of this study is to evaluate the efficacy, safety and impact on quality of life related to oral health of tooth whitening techniques in young individuals. It will be a randomized, parallel and single blind. Participants are divided into three groups (n = 30) according to bleaching technique to be performed (G1 = Office / hydrogen peroxide 6%; G2 = Office / hydrogen peroxide 15%; G3 = Home / carbamide peroxide 10%). The color of the teeth will be evaluated in seven different times, using the color scale Vita Master Classic 3D and spectrophotometer Vita Easy Shade Advance. IGM (1986) - the presence of tooth sensitivity by visual analogue scale and gingival security through modified gingival index will be evaluated. The impact of bleaching quality of life will be assessed using the Brazilian version of the oral impact on daily performance (OIDP). The instrument will be applied in interview form at two different times at baseline (T0) and thirty days after the first evaluation (T4). Statistical analysis include descriptive analysis and testing to compare the two bleaching techniques as the color change, sensitivity, gum irritation and impact on quality of life.
