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.
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.

Evaluation of color change
Visual evaluation using color scale Vita Classical 3D Master (Vita Zahnfabrik, Germany); (B1, A1, B2, D2, A2, C1, C2, D4, A3, D3, B3, A3.5, B4, C3, A4, C4) Quantitative evaluation using a spectrophotometer Easy Shade Advance ® (Wilcos Brazil). System CIE L \* a \* b \* - L represents the value (lightness or darkness), the value of a \* is a measure red (positive a \*) or green (negative a \*); the value of b \* is a yellow extent (b \* positive) or blue (b \* negative) and the color difference between the color coordinate is calculated as ΔE \* = \[(ΔL \*) 2 + (Δa \*) 2 + (Δb \*) 2\] 1/2.
Time frame: T0 (Baseline): Before treatment;T1:After one week of starting treatment;T2: After 2 weeks of starting treatment;T3: After 3 weeks of starting treatment;T4: After 30 days of starting treatment;T5:After 6 months ;T6:After 12 months
Tooth sensitivity assessment
It will be registered according to the Visual Analogue Scale (VAS), according to the criteria: none, mild, moderate or severe.
Time frame: T0 (Baseline): Before treatment;T1:After one week of starting treatment;T2: After 2 weeks of starting treatment;T3: After 3 weeks of starting treatment;T4: After 30 days of starting treatment;
Evaluation of gingival irritation
The Modified Gingival Index (IGM) The criteria are as follows: 0: Absence of inflammation;1: mild inflammation - slight change in color and texture of the gum; 2: mild inflammation involving the entire gingival margin; 3: moderate inflammation, shiny surface and edema; 4: Severe inflammation, spontaneous bleeding and severe edema.
Time frame: T0 (Baseline): Before treatment;T1:After one week of starting treatment;T2: After 2 weeks of starting treatment;T3: After 3 weeks of starting treatment;T4: After 30 days of starting treatment;
Impact assessment on quality of life
The Brazilian version of the oral impact on daily performance (OIDP) will be used to assess the impact on quality of life. The instrument will be applied in interview form at two different times at baseline (T0) and thirty days after the first evaluation (T4) to assess the perception of changes in oral health after treatment.
