Influência do peróxido de hidrogênio sobre a diferenciação celular e a mineralização do tecido pulpar após procedimento clareador: estudo histológico e imunoistoquímico

Introdução Através de modelo experimental caracterizado por nosso grupo de pesquisa, e protocolo clareador adaptado, verificamos que o peróxido de hidrogênio (H2O2) contido no gel clareador pode gerar efeitos ao tecido pulpar, que ainda não estão completamente compreendidos. Outros estudos mostram...

Análise de citotoxicidade, desmineralização e potencial clareador de géis clareadores experimentais, baseado em peróxido de carbamida 15% adicionados de nano-hidróxiapatita

O clareamento dental é considerado um procedimento muito seguro, de efeito rápido e agradável, tornando-se um dos procedimentos mais realizados na odontologia. Contudo, o mesmo apresenta alguns efeitos colaterais, sendo o principal deles a sensibilidade dental, que pode ser causada pela citotoxidade, ...

Con el avance en las técnicas de blanqueamiento dental, el advenimiento de nuevos biomateriales capaces de lograr resultados estéticos aceptables por los pacientes; sabiendo que en la operatoria dental muchos autores priorizan iniciar dicho tratamiento restaurador con el aclareamiento dental. Como cons...

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...

Can whitening toothpastes maintain the optical stability of enamel over time?

J. appl. oral sci; 26 (), 2018
Abstract Besides the effects on the health of individuals, cigarette smoking can also interfere with the appearance of their teeth. Objective: To evaluate the effect of cigarette smoking-toothbrushing-cycling (CSTC) with whitening toothpastes on the roughness and optical behavior of bovine enamel for ei...

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...

In-office tooth bleaching with 38% hydrogen peroxide promotes moderate/severe pulp inflammation and production of ll-1β, TNF-β, GPX, FGF-2 and osteocalcin in rats

J. appl. oral sci; 26 (), 2018
Abstract Objectives: To study the intensity of inflammatory infiltrate and production of interleukin-1β (ll-1β), tumor necrosis factor-β (TNF-β), fibroblast growth factor-2 (FGF-2), glutathione peroxidase (GPX), and osteocalcin in response to in-office tooth bleaching in rats. Mater...
