Bleaching Tooth of Low Concentration Domestic and Office

2016-06-28 21:23:21 | BioPortfolio


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.

Calcium Phosphate Microspheres as a Delivery Vehicle for Tooth-Bleaching Agents.

Bleaching of vital teeth has become common practice in cosmetic dentistry today. Tooth sensitivity and demineralization of the enamel are, however, common side effects associated with hydrogen and car...

The origin of hydrogen peroxide in oral cavity and its role in oral microecology balance.

Hydrogen peroxide, an important antimicrobial agent in oral cavity, plays a significant role in the balance of oral microecology. At the early stage of biofilm formation, about 80% of the detected ini...

OO bond homolysis in hydrogen peroxide.

OO bond homolysis in hydrogen peroxide (H2 O2 ) has been studied using theoretical methods of four conceptually different types: hybrid DFT (B3LYP, M06-2X), double-hybrid DFT (B2-PLYP), coupled-clu...

Generation of superoxide and hydrogen peroxide by side reactions of mitochondrial 2-oxoacid dehydrogenase complexes in isolation and in cells.

Mitochondrial 2-oxoacid dehydrogenase complexes oxidize 2-oxoglutarate, pyruvate, branched-chain 2-oxoacids and 2-oxoadipate to the corresponding acyl-CoAs and reduce NAD+ to NADH. The isolated enzyme...

Hydroxyl radical yields in the Fenton process under various pH, ligand concentrations and hydrogen peroxide/Fe(II) ratios.

The Fenton process, one of several advanced oxidation processes, describes the reaction of Fe(II) with hydrogen peroxide. Fe(II) is oxidized to Fe(III) that reacts with hydrogen peroxide to Fe(II) and...

Medical and Biotech [MESH] Definitions

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

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

A hemeprotein which catalyzes the oxidation of ferrocytochrome c to ferricytochrome c in the presence of hydrogen peroxide. EC

Peroxidase catalyzed oxidation of lipids using hydrogen peroxide as an electron acceptor.
