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...

Sealing Carious Fissures with Resin Infiltrant in Association with a Flowable Composite Reduces Immediate Microleakage?

Abstract Objective: To compare the immediate microleakage of carious fissures sealed with a caries infiltrant covered by a flowable composite or solely with a flowable composite. Material and Methods: Extracted carious molars (n=20) were selected and paired among the experimental groups according to ca...

Adaptación de pilares rectos sobre implantes con conexión hexagonal interna y externa por microscopía electrónica de barrido

Odontología (Ecuad.); 22 (1), 2020
En implantología oral, ha sido motivo de investigación y constante evolución la interfase implante-pilar, princi-palmente desde el punto de vista biomecánico y biológico. Objetivo: Valorar el espacio o “gap” en la interfase implante-pilar en implantes de conexión hexagonal interna y externa por...

Microfiltraciones entre ionómero de vidrio y resina compuesta en lesiones clase-V no cariosas

Odontología (Ecuad.); 22 (1), 2020
No se han establecido estándares para el tratamiento de cavidades cervicales no cariosas; un biomaterial adecuado permitirá buena adaptación y longevidad de la restauración. Objetivo: Determinar la microfiltración en cavidades clase V no cariosas restauradas con ionómero de vidrio y ...

Resin-dentin bond stability of etch-and-rinse adhesive systems with different concentrations of MMP inhibitor GM1489

J. appl. oral sci; 28 (), 2020
Abstract Enzymatic degradation of the hybrid layer can be accelerated by the activation of dentin metalloproteinases (MMP) during the bonding procedure. MMP inhibitors may be used to contain this process. Objective To evaluate the degree of conversion (DC%), dentin bond strength (µTBS) (immediate and ...

Evaluation of marginal fit and microleakage of monolithic zirconia crowns cemented by bio-active and glass ionomer cements: In vitro study

Braz. dent. sci; 23 (1), 2020
Objective: to evaluate the marginal fit and microleakage of monolithic zirconia crowns cemented by bio-active cements (Ceramir) compared to that cemented with glass ionomer cement, and to evaluate the effect of thermocycling on marginal fit. Material and Methods: Twenty sound human molar teeth were prepa...

Evaluation of microleakage and the degree of conversion of three composite resins polymerized at different power densities

Braz. dent. sci; 23 (2), 2020
Objectives: This study aims to evaluate the degree of conversion (DC) and microlekage scores of three different composite resins polymerized with a LED curing device in standard and extra-power mode. Material and Methods: One bulk-fill (Tetric EvoCeram Bulk-Fill – TECBF) and two conventional composite ...

The finish line location of the cemented crown is an influencing factor for tensile bond strength, marginal adaption and nanoleakage?

Braz. dent. sci; 23 (2), 2020
Objective: The aim of this study was to evaluate the influence of different crowns finishing line location on the crown tensile bond strength, marginal adaption and nanoleakage. Material and Methods: Sixty healthy third molars were collected. For tensile bond strength, a self-adhesive resin cement was us...

Evaluation of the apical microleakage of MTA Fillapex, AH26, and Endofill sealers

Braz. dent. sci; 23 (3), 2020
Objective: Proper apical seal plays an important role in the success of root canal treatment. The most common cause of failure of root canal therapy is known as the lack of adequate apical seal. The aim of this in vitro study was to compare the apical microleakage of MTA Fillapex, AH26, and Endofill seal...
