Resistencia de unión de cerámica feldespática a esmalte bovino empleando diferentes cementos resinosos

Rev. cient. odontol; 3 (2), 2015
OBJETIVO: Comparar la resistencia de unión de cerámica feldespática al esmalte bovino entre las diferentes marcas de cementos resinosos autoadhesivos y un cemento resinoso dual universal.MATERIALES Y MÉTODOS: Se utilizaron ocho incisivos inferiores sanos de bovino divididos en cuatro g...

Swelling of self-adhesive resin cement increases long-term push-out bond strength of fiber post to dentin

Braz. j. oral sci; 14 (3), 2015
Abstract Aim: To evaluate the long-term post push-out bond strength to dentin, water sorption, solubility and swelling of conventional and self-adhesive dual-cure resin cements. Methods: Forty-eight bovine roots were prepared for fiber post cementation with RelyX ARC and RelyX U100. According to resin ce...

One-year clinical evaluation of the retention of resin and glass ionomer sealants on permanent first molars in children

Braz. j. oral sci; 14 (3), 2015
Abstract Aim : To compare the retention of glass ionomer cement (GIC) used as fissure sealant with a resinbased sealant. Methods: Six- to nine-year-old children (n=96) with all permanent first molars in occlusion were examined and assigned to two groups: GIC sealant or resin-based sealant. The sealants w...

Four chemical methods of porcelain conditioning and their influence over bond strength and surface integrity

OBJECTIVE: To assess four different chemical surface conditioning methods for ceramic material before bracket bonding, and their impact on shear bond strength and surface integrity at debonding.METHODS: Four experimental groups (n = 13) were set up according to the ceramic conditioning method: G1 = 37% p...

Efeito da intensidade de fontes de luz e barreiras de cerâmica na microdureza de cimento resinoso dual

Introdução: O cimento resinoso dual é o principal material para cimentação de cerâmicas. Contudo, fatores, como fonte de luz, podem influenciar no desempenho do cimento. Objetivo: Avaliar a influência de duas fontes de luz de diferentes intensidades sobre a microdureza de um cimento resinoso quand...

Efecto del acondicionamiento de la dentina con ácido poliacrílico al 15 % sobre la resistencia de unión de los cementos resinosos autoadhesivos

Rev. cient. odontol; 3 (1), 2015
OBJETIVO: Evaluar el efecto del ácido poliacrílico al 15% (APA) aplicado por 10 y 20 segundos (s) en la dentina humana sobre la resistencia de unión de los cementos resinosos autoadhesivos. METODOLOGÍA: Se dividieron aleatoriamente veintisiete terceras molares en nueve grupos Maxcem Elite control (ME...

Evaluación de la microdureza de cementos resinosos de uso odontológico: estudio in vitro

Rev. cient. odontol; 3 (1), 2015
OBJETIVO: Es importante conocer las propiedades mecánicas de los materiales dentales para poder determinar crítica-mente su comportamiento y no limitarnos únicamente a la evaluación clínica. Por esa razón, el objetivo de este estudio fue comparar la microdureza de cuatro cementos resinosos de uso o...

Influência de diferentes tratamentos de superfície na força de adesão entre zircônia estabilizada por ítria e cimentos resinosos

Rev. bras. odontol; 72 (1/2), 2015
O objetivo da presente revisão de literatura foi avaliar a influência de tratamentos de superfície na força de adesão entre zircônia estabilizada por ítria e cimento resinoso. De acordo com a literatura pesquisada, concluiu-se, dentro das limitações do estudo, que a silicatização e o jateament...

Do resin cements influence the cuspal deflection of teeth restored with composite resin inlays?

Acta odontol. latinoam; 28 (1), 2015
The aim of this study was to evaluate the influence of different resin cements on the cuspal deflection of endodontically treated teeth restored with composite resin inlays. Sixty upper premolars were randomly divided into five groups (n=12): 1 - sound teeth; 2 - cavity; 3 - Rely X ARC; 4 - RelyX Unicem;...

Influence of addition of 2-[3-(2H-benzotriazol-2-YL)- 4-hydroxyphenyl] ethyl methacrylate to an experimental adhesive system

Acta odontol. latinoam; 28 (1), 2015
The aim of this study was to evaluate the addition of 2-[3-(2HBenzotriazol- 2-yl)-4-hydroxyphenyl]ethyl methacrylate (BTAM) to an experimental adhesive resin. An experimental base adhesive resin was formulated with BisGMA, TEGDMA and HEMA, to which BTAM was added at 1, 2.5 and 5%, in weight. One group wi...
