Surface morphology and in vitro leachability of soft liners modified by the incorporation of antifungals for denture stomatitis treatment

J. appl. oral sci; 28 (), 2020
Abstract Objective: To evaluate the surface morphology and in vitro leachability of temporary soft linings modified by the incorporation of antifungals in minimum inhibitory concentrations (MIC) for Candida albicans biofilm. Methodology:Specimens of soft lining materials Softone and Trusoft were made w...

Effect of different surface treatments and multimode adhesive application on the Weibull characteristics, wettability, surface topography and adhesion to CAD/CAM lithium disilicate ceramic

J. appl. oral sci; 28 (), 2020
Abstract This paper aims to evaluate the effect of different surface treatments on surface topography, wettability, and shear bond strength of resin cement to glass ceramic. Methodology: For SBS test, 32 blocks (7x7x2 mm) of lithium disilicate were obtained and randomly divided into eight groups (four b...

Effect of a novel bioceramic root canal sealer on the angiogenesis-enhancing potential of assorted human odontogenic stem cells compared with principal tricalcium silicate-based cements

J. appl. oral sci; 28 (), 2020
Abstract Objective: This study evaluated the angiogenesis-enhancing potential of a tricalcium silicate-based mineral trioxide aggregate (ProRoot MTA), Biodentine, and a novel bioceramic root canal sealer (Well-Root ST) in human dental pulp stem cells (hDPSCs), human periodontal ligament stem cells (hPLS...

Nanopartículas de clorexidina-hexametafosfato na endodontia: síntese, caracterização, avaliação biológica e físico-química da incorporação aos cimentos endodônticos

Este estudo avaliou as influências da incorporação de nanopartículas (NPs) de clorexidina-hexametafosfato em diversas propriedades dos cimentos endodônticos: AH Plus, MTA Fillapex e Pulp Canal Sealer (PCS). As NPs foram sintetizadas através de uma suspensão contendo 5 mM de hexametafosfato de sód...

Propriedades físico-químicas de cimentos endodônticos à base de óxido de zinco e eugenol

Arq. odontol; 56 (), 2020
Objetivo: Analisar as propriedades físico-químicas, escoamento, tempo de presa, solubilidade e alteração dimensional, dos cimentos endodônticos à base de óxido de zinco e eugenol: Endomethasone N, Endofill e Grosmann, de acordo com a especificação número 57 da American Dental Association. Méto...

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 ...

Can the size and the luting material influence in the bond strength of the fiberglass post to dentin?

Arq. odontol; 56 (), 2020
Aim: To evaluate the influence of lengths and different luting agents on the bond strength of fiberglass posts’ adhesion to dentin.Methods: Sixty single-root bovine teeth were endodontically treated and included in polyether and acrilyc resin to simulate a periodontal ligament. These were divided into ...

Repair bond strength and degradation of glass ionomer cements after mechanical and chemical challenges

Braz. j. oral sci; 19 (), 2020
Aim: Little is known about the reparability of glass ionomer cements (GICs) after storage in acid environments. The aim of this study was to evaluate the solubility and repairability of GICs immersed in acid solutions and subjected to brushing. Methods: Thirty discs of each GIC (Vitremer, VitroFil LC, Vi...

Radiopacidad de Materiales Utilizados Como Sustituto Dentinario
Radiopacity of Materials Used as Dentin Substitutes

El objetivo de este estudio fue comparar la radiopacidad de distintos materiales utilizados como sustitutos de la dentina según norma ISO 6876. Se utilizaron Biodentine-Septodont (a base de silicato de calcio), Equia Forte – GC Corporation (ionómero vítreo convencional), Sure Fill SDR Flow – Dents...

Efecto de Diferentes Técnicas de Acabado y Pulido Sobre la Rugosidad de un Composite de Nanoparticulas
Effect of Different Finishing and Polishing Techniques on the Roughness of a Nanoparticle Composite

El objetivo fue comparar la rugosidad de un composite nanoparticulado con diferentes técnicas de acabado y pulido. Se obtuvieron 20 discos en conformadores ad-hoc en los que se insertó un composite nanoparticulado en capas de 2mm. Se activó cada incremento durante 30s con una intensidad de 1450 mw/cm2...
