Bond strength of composite resin/universal adhesive to dentin submitted to radiotherapy

J. oral res. (Impresa); 12 (1), 2023
Aim: To evaluate the bond strength of a universal adhesive system to dentin submitted to radiotherapy. Materials and Methods: Sixty extracted human teeth were divided into two groups (n = 30): without radiotherapy (control); with radiotherapy, according to the adhesive protocol (n=15): ER-etch-and-rinse ...

Acid-Base Resistant Zone in Teeth with the Direct Restoration Using Different Adhesive System Generations: A Systematic Review

ABSTRACT Objective: To find out what the acid-base resistant zone (ABRZ) is and the mechanism of its formation. Material and Methods: This systematic review was based on the search of laboratory studies in which selfetching adhesive systems were used. The electronic database PubMed was used for the sea...

Prueba de Push-Out para Evaluar la Fuerza de Adhesión entre dos Tipos de Postes Estéticos

Posterior a un tratamiento endodóntico, muchas veces el remanente es insuficiente para la retención de un material de restauración, por este motivo es necesario la colocación de un sistema de poste-muñón para otorgar retención a la restauración final. Con la aparición de diversos materiales para...

Efecto Antimicrobiano de Tres Cementos Selladores Endodónticos frente a Streptococcus mutans, Enterococcus faecalis y Candida albicans

El objetivo del estudio fue evaluar el efecto antimicrobiano de tres cementos selladores endodónticos frente a Streptococcus mutans, Enterococcus faecalis y Candida albicans. Se usó el método de difusión en agar, realizando pozos de 5 mm de diámetro por 4 mm de profundidad, en donde se colocaron los...

Sistemas adesivos universais – há 10 anos no Brasil: revisão de literatura

Objetivo: analisar, a partir da literatura publicada, os sistemas adesivos universais, conceituando sobre seu desempenho nos diferentes substratos, assim como potenciais estudos executados com eles após 10 anos no Brasil. Materiais e métodos: para esta revisão narrativa, foram pesquisados artigos na l...

Adhesive resistance of a copaiba oil-based dentin biomodifier

Abstract This study analyzed the effect of prior application of copaiba oil (CO) emulsions as a dentin cleaning substance on microleakage and microtensile adhesive strength. Twenty-five premolars and sixty-four molars were used for microleakage and microtensile assays. For the microleakage assays, specim...

Effect of 10% sodium ascorbate applied for different time periods on shear bond strength of composite to bleached enamel

J. oral res. (Impresa); 8 (4), 2019
Aims: Residual peroxide on the enamel surface and in the interprismatic spaces decreases the shear bond strength (SBS) of composite to bleached enamel. Evidence shows that 10% sodium ascorbate can efficiently neutralize the singlet oxygen generated by the bleaching agents. This study aimed to assess the ...

Influência de inibidores de metaloproteinases na degradação da camada híbrida

RFO UPF; 24 (1), 2019
Objetivo: realizar uma revisão de literatura acerca da eficácia de utilização da clorexidina (CHX) e de outros tipos de inibidores de metaloproteinases (MMPs) na resistência de união da camada híbrida. Métodos: a busca bibliográfica foi realizada na base de dados PubMed, nos meses de novembro e ...

Microtensile bond strength of root canal dentin treated with adhesive and fiber-reinforced post systems

Abstract Nowadays, demand for esthetic restorations has risen considerably; thus, nonmetal esthetic posts made of either high-strength ceramics or reinforced resins, such as fiber-reinforced resin posts, have become more and more popular. Important characteristics of fiber-reinforced posts involve a modu...
