Rubbing time and bonding performance of one-step adhesives to primary enamel and dentin

J. appl. oral sci; 25 (5), 2017
Abstract Objectives: This study investigated whether increasing the concentration of acidic monomers in one-step adhesives would allow reducing their application time without interfering with the bonding ability to primary enamel and dentin. Material and methods: Experimental one-step self-etch adhesiv...

Does laser diode irradiation improve the degree of conversion of simplified dentin bonding systems?

J. appl. oral sci; 25 (4), 2017
Abstract Simplified dentin-bonding systems are clinically employed for most adhesive procedures, and they are prone to hydrolytic degradation. Objective This study aimed to investigate the effect of laser diode irradiation on the degree of conversion (DC), water sorption (WS), and water solubility (WSB...

Correlación entre el comportamiento térmico y composición de sistemas adhesivos

Se realizó un estudio in vitro donde se evaluaron once sistemas adhesivos, para establecer si las condiciones de trabajo clínico favorecen su eficiencia. Se plantea que los sistemas adhesivos autoacondicionantes presentan menor estabilidad térmica que los convencionales. Determinar el comportamiento t...

Effect of Sonic Vibrations on Bond Strength of Fiberglass Posts Bonded to Root Dentin

Braz. dent. j; 28 (1), 2017
Abstract Sonic vibrations may improve the bond strength and durability of fiberglass posts by improving adhesive penetration into dentin as well as the cement flow. The objective of this study was to evaluate the effect of sonic vibrations on the bond strength between fiberglass posts and root dentin usi...

Efeito da irradiação com laser de diodo sobre adesivos dentinários: estudo in vitro

A irradiação de sistemas adesivos com laser tem obtido resultados promissores, no entanto, seu mecanismo de ação, bem como a longevidade da camada híbrida obtida após a irradiação com laser ainda não estão bem estabelecidos na literatura. A presente tese teve como objetivo: avaliar a absorvânc...

Ethanol-wet bonding technique: 18-month clinical evaluation

The objective of this randomized clinical trial was to evaluate the clinical performance up to 18 months of restorations placed using ethanol-wet bonding technique (EWBT) compared with the three-step etch-and-rinse (TSER) and one-step self-etching (OSSE) approaches. Ninety-three non-carious cervical lesi...

Water interaction and bond strength to dentin of dye-labelled adhesive as a function of the addition of rhodamine B

J. appl. oral sci; 24 (4), 2016
ABSTRACT Objective This study investigated the effect of the fluorescent dye rhodamine B (RB) for interfacial micromorphology analysis of dental composite restorations on water sorption/solubility (WS/WSL) and microtensile bond strength to dentin (µTBS) of a 3-step total etch and a 2-step self-etch ad...

Effect of green tea extract on bonding durability of an etch-and-rinse adhesive system to caries-affected dentin

J. appl. oral sci; 24 (3), 2016
ABSTRACT Objective Green tea extract has been advocated as a matrix metalloproteinase (MMP) inhibitor; however, its effect on bond durability to caries-affected dentin has never been reported. Thus, the aim of this in vitro study was to evaluate the effect of two MMP inhibitors (2% chlorhexidine and 2%...

Influência do tempo de condicionamento ácido na alteração superficial, resistência de união e compressão da cerâmica de dissilicato de lítio

Este estudo in vitro propôs analisar os padrões de condicionamento da superfície da cerâmica a base de dissilicato de lítio após três tempos de condicionamento com ácido fluorídrico a 10%, a influência desses tempos na resistência ao cisalhamento de cilindros cerâmicos e à compressão...

Relined fiberglass post: an ex vivo study of the resin cement thickness and dentin-resin interface

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate the thickness of resin cements in the root thirds when using conventional fiberglass posts (CP) and relined fiberglass posts (RP) in weakened roots and to evaluate the morphological characteristics of the dentin-resin interface. Forty human maxillary anterio...
