Effect of Sodium Ascorbate or Alpha-Tocopherol on the Resin-Dentin Interface and Bond Strength after Endodontic Treatment and Bleaching

The objective of this in vitro study was to assess the effects of two antioxidants (sodium ascorbate [SA] and alpha-tocopherol [AT]) on the adhesive interface and dentin bond strength immediately after bleaching with 38 % hydrogen peroxide (38HP) in endodontically-treated teeth. Two stages of experimenta...

Evaluation of Dental Enamel Mass in Prolonged Supervised Dental Bleaching Protocol with Calcium-Containing Gel

The objective of this study was to determine the enamel mass variation after a prolonged bleaching treatment using a calcium-containing 4% hydrogen peroxide gel Twenty sound bovine incisors were randomly assigned to two groups (n=10) stored in G1) distilled water and G2) artificial saliva. An electronic ...

Influência do LED Violeta associado ou não ao gel clareador na inflamação, mineralização e maturação colágena do tecido dentinário e pulpar

Objetivo: Avaliar a influência do LED Violeta, associado ou não ao gel clareador a base de peróxido de hidrogênio (PH) a 17,5% no complexo dentino-pulpar de ratos. Materiais e métodos: Molares superiores de 80 ratos foram distribuídos nos grupos (n = 10): CONT – sem tratamento, PH – 1 aplicaç...

Efecto de cocción en horno convencional y microondas sobre rancidez, pérdida por cocción y diferencia sensorial de hamburguesas

Rev. chil. nutr; 47 (2), 2020
El uso de microondas está muy extendido a nivel doméstico gracias a su rapidez y facilidad de uso. El objetivo del presente trabajo es comparar el efecto de cocción de hamburguesas de distintos tipos de carne, en microondas y en horno convencional, sobre la pérdida de peso y estabilidad oxidativa. Ad...

Titanium dioxide nanotubes incorporated into bleaching agents: physicochemical characterization and enamel color change

J. appl. oral sci; 28 (), 2020
Abstract Titanium dioxide nanotubes are nanostructures that can accelerate the oxidation reaction of bleaching procedures and promote a more effective whitening effect. Objective This study evaluated physicochemical properties of bleaching agents incorporated with titanium dioxide (TiO2) nanotubes, and...

Evaluation of reservoirs in bleaching trays for at-home bleaching: a split-mouth single-blind randomized controlled equivalence trial

J. appl. oral sci; 28 (), 2020
Abstract Objectives This randomized, split-mouth, single-blinded trial assessed whether the use of reservoirs in at-home bleaching trays is equivalent to non-reservoir trays. Our choice of an equivalence trial was based on the expectation that a non-reservoir tray is sufficient to produce a color change...

Determinación de la rancidez en aceites usados en el proceso de frituras en establecimientos de expendió de comida rápida

Con-ciencia (La Paz); 8 (2), 2020
INTRODUCCIÓN: en la actualidad se ha producido un incremento sustancial del consumo de alimentos procesados en frituras con aceites vegetales expedidos en establecimientos de comida rápida, que son de elección para muchas personas principalmente por trabajadores y estudiantes por el horario limitado c...

Influence of Prolonged Tooth Bleaching on Enamel Mass Variation

ABSTRACT: The objective evaluate was the influence of prolonged tooth bleaching with 10 % carbamide peroxide (10CP) on tooth enamel mass variation. Ten healthy bovine incisor teeth were divided (n = 5) into G1 - storage in distilled water and G2 - storage in artificial saliva. The samples were weighed in...

Decomposition rate, ph, and enamel color alteration of at-home and in-office bleaching agents

Braz. dent. j; 30 (4), 2019
Abstract This study evaluated the decomposition rate (DR), pH, enamel color alteration (DE) and whiteness index (DWI) promoted by at-home and in-office bleaching. Enamel surface was submitted to (n=10): at-home (10%, 15%, 20% carbamide peroxide - CP, 6% hydrogen peroxide -HP) and three 35% HP agents with...

Cholinesterase inhibitory activity, antioxidative potential and microbial stability of innovative liver pâté fortified with rosemary extract (Rosmarinus officinalis)

Background: Rosemary (Rosmarinus officinalis) contains active substances that have desirable properties for industrial and herbal medicine applications, e.g., essential oils (1.5–2.5%), tannins, flavonoids, triterpenes, saponins, resins, phytosterols, rosmarinic acid and many others. The aim of this st...
