Efeito do pH do gel clareador de consultório na cor e na sensibilidade dentária

Rev. Ciênc. Plur; 9 (3), 2023
Introdução:Sabe-se que a busca pela estética é algo cada vez mais crescente. Dentre os procedimentos mais procurados na odontologia estética, destaca-se o clareamento dental de consultório. Diante disso, ainda são poucos os estudos que avaliam os efeitos dos agentes clareadores de ...

Coadministration of ibuprofen/caffeine on bleaching-induced tooth sensitivity: A randomized clinical trial

Braz. dent. j; 32 (3), 2021
Abstract This clinical trial evaluated the effect of the coadministration of ibuprofen/caffeine on bleaching-induced tooth sensitivity (TS). A triple-blind, parallel-design, randomized clinical trial was conducted on 84 patients who received ibuprofen/caffeine or placebo capsules. The drugs were administ...

Experimental gel containing bioactive glass-ceramic to minimize the pulp damage caused by dental bleaching in rats

J. appl. oral sci; 28 (), 2020
Abstract Objectives This study evaluated if the use of a bioactive glass-ceramic-based gel, named Biosilicate (BS), before, after or mixed with bleaching gel, could influence the inflammation of the dental pulp tissue of rats' molars undergoing dental bleaching with hydrogen peroxide (H2O2). Methodolo...

Do commercial whitening dentifrices increase enamel erosive tooth wear?

J. appl. oral sci; 28 (), 2020
Abstract Objective This in vitro study evaluated the effect of commercial whitening dentifrices on erosive tooth wear (ETW) of bovine enamel samples, in comparison with commercial regular dentifrices. Methodology Sixty bovine crowns were embedded in acrylic resin, polished and then had their baseline...

Effect of dental bleaching on pulp oxygen saturation in maxillary central incisors - a randomized clinical trial

J. appl. oral sci; 27 (), 2019
Abstract Objective To assess pulp oxygen saturation levels (SaO2) in maxillary central incisors after dental bleaching. Materials and Methods 80 participants (160 teeth) were randomly allocated to four groups: G1 In-office bleaching with two applications of 35% hydrogen peroxide (HP) (20 minutes), fo...

Neurosensory analysis of tooth sensitivity during at-home dental bleaching: a randomized clinical trial

J. appl. oral sci; 26 (), 2018
Abstract Objective The objective of this study was to evaluate dental sensitivity using visual analogue scale, a Computerized Visual Analogue Scale (CoVAS) and a neurosensory analyzer (TSA II) during at-home bleaching with 10% carbamide peroxide, with and without potassium oxalate. Materials and Method...

Preemptive use of etodolac on tooth sensitivity after in-office bleaching: a randomized clinical trial

J. appl. oral sci; 26 (), 2018
Abstract Purpose: This study determined the effectiveness of the preemptive administration of etodolac on risk and intensity of tooth sensitivity and the bleaching effect caused by in-office bleaching using 35% hydrogen peroxide. Material and methods: Fifty patients were selected for this tripleblind, ...

Influence of skin cold sensation threshold in the occurrence of dental sensitivity during dental bleaching: a placebo controlled clinical trial

J. appl. oral sci; 26 (), 2018
Abstract Objective This study verified the occurrence of dental sensitivity in patients submitted to a 35% hydrogen peroxide based product (Whiteness HP Maxx 35% - FGM), skin cold sensation threshold (SCST) and its influence on dental sensitivity. Material and Methods Sixty volunteers were divided into...

Effects of experimental bleaching agents on the mineral content of sound and demineralized enamels

J. appl. oral sci; 26 (), 2018
Abstract High concentrations of hydrogen peroxide can cause adverse effects on composition and structure of teeth. However, the addition of calcium and fluoride in bleaching agents may reduce enamel demineralization. Objective: To evaluate chemical changes of sound and demineralized enamels submitted to...

High-concentration carbamide peroxide can reduce the sensitivity caused by in-office tooth bleaching: a single-blinded randomized controlled trial

J. appl. oral sci; 26 (), 2018
Abstract Objectives A single-blinded, randomized, parallel clinical trial evaluated the use of 37% carbamide peroxide (CP) on bleaching effectiveness and tooth sensitivity reported by patients undergoing in-office tooth bleaching, in comparison with the results of using 35% hydrogen peroxide. Material...
