Influence of a hydrophobic monomer on the physical and mechanical properties of experimental surface sealants

Abstract This study evaluated the effect of adding the hydrophobic monomer 1,12 dodecanediol dimethacrylate (DDDMA) to experimental sealants with and without thermocycling on degree of conversion (DC), water sorption (WS), water solubility (WSB), color stability (ΔE), and micro-shear bond strength (...

Effect of cavity preparation design and ceramic type on the stress distribution, strain and fracture resistance of CAD/CAM onlays in molars

J. appl. oral sci; 26 (), 2018
Abstract Objective This study aimed to evaluate the effect of the cavity preparation and ceramic type on the stress distribution, tooth strain, fracture resistance and fracture mode of human molar teeth restored with onlays. Material and Methods Forty-eight molars were divided into four groups (n=12)...

Surface, thermal and hemocompatible properties of novel single stage electrospun nanocomposites comprising polyurethane blended with bio oilTM

An. acad. bras. ciênc; 89 (3,supl), 2017
ABSTRACT In this work, the physicochemical and blood compatibility properties of prepared PU/Bio oil nanocomposites were investigated. Scanning electron microscope (SEM) studies revealed the reduction of mean fiber diameter (709 ± 211 nm) compared to the pristine PU (969 nm ± 217 nm). Fourier transform...

Influence of resin cement shade on the color and translucency of ceramic veneers

J. appl. oral sci; 24 (4), 2016
ABSTRACT Objective This in vitro study evaluated the effect of two different shades of resin cement (RC- A1 and A3) layer on color change, translucency parameter (TP), and chroma of low (LT) and high (HT) translucent reinforced lithium disilicate ceramic laminates. Material and Methods One dual-cured...

Optimizing light-cured composite through variations in camphorquinone and butylhydroxytoluene concentrations

Braz. oral res. (Online); 30 (1), 2016
Abstract The use of a free-radical polymerization inhibitor, butylhydroxytoluene (BHT), and a common photo-initiator, camphorquinone (CQ), to reduce polymerization stress in dental composite was investigated in this study. Samples were prepared by mixing Bis-GMA, UDMA, and TEGDMA at a 1:1:1 ratio (wt%), ...

Estudo de complicações em próteses mamárias: avaliação de 546 casos em oito anos

Rev. bras. cir. plást; 29 (3), 2014
INTRODUÇÃO: O implante de próteses mamárias é uma das cirurgias mais frequentes e desafiadoras da cirurgia plástica, devido às complicações associadas. MÉTODO: Foi realizado um estudo retrospectivo de 546 pacientes operadas em oito anos (maio de 2004 a maio de 2012), sendo estudadas todas as pa...

Mastopexia periareolar (circum-areolar) com implante mamário cônico: tratamento de ptose, hipomastia e alterações de posição e tamanho do complexo aréolo-papilar

Rev. bras. cir. plást; 29 (3), 2014
INTRODUÇÃO: A cirurgia de mastopexia associada ao aumento mamário vem sendo cada vez mais solicitada. Ao mesmo tempo, pacientes com graus menores de ptose aceitam menos as correções por meio de cicatrizes verticais. Nesse contexto, a mastopexia periareolar (circum-areolar) com implante cônico é um...
