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.

Electrochemical analysis of intracellular hydrogen peroxide in sub-micron scaled cellular protrusion is challenging that requires highly sensitive nanoelectrode and advanced electrochemical detection ...
To evaluate the risk for and intensity of tooth sensitivity and color change of at-home dental bleaching with 4% and 10% hydrogen peroxide (HP).
An oxidoreductase that catalyzes the reaction between superoxide anions and hydrogen to yield molecular oxygen and hydrogen peroxide. The enzyme protects the cell against dangerous levels of superoxide. EC 126.96.36.199.
A peroxide derivative that has been used topically for BURNS and as a dermatologic agent in the treatment of ACNE and POISON IVY DERMATITIS. It is used also as a bleach in the food industry.
An enzyme of the oxidoreductase class that catalyzes the conversion of beta-D-glucose and oxygen to D-glucono-1,5-lactone and peroxide. It is a flavoprotein, highly specific for beta-D-glucose. The enzyme is produced by Penicillium notatum and other fungi and has antibacterial activity in the presence of glucose and oxygen. It is used to estimate glucose concentration in blood or urine samples through the formation of colored dyes by the hydrogen peroxide produced in the reaction. (From Enzyme Nomenclature, 1992) EC 188.8.131.52.
Peroxidase catalyzed oxidation of lipids using hydrogen peroxide as an electron acceptor.
A hemeprotein which catalyzes the oxidation of ferrocytochrome c to ferricytochrome c in the presence of hydrogen peroxide. EC 184.108.40.206.
