Colitis linfocítica en paciente con colitis ulcerosa: caso clínico

Rev. méd. Chile; 144 (8), 2016
The relationship between Microscopic Colitis and Inflammatory Bowel Disease is unclear. However, when both are diagnosed they seem to be part of a broader spectrum of the same disease, more than just a coincidence. We report a 55 years old woman with Ulcerative Colitis limited to the rectum with complete...

Evaluación In vitro de la Resistencia a la Fractura de los Pilares Individualizados en Disilicato de Litio

Los pilares híbridos individualizados en disilicato de litio, permiten adaptarse a la forma y el perfil de emergencia obtenido después de la temporalización de los implantes, presentando buenas características ópticas y determinando la posibilidad de una cementación adhesiva. El propósito del estu...

Insuficiencia suprarrenal relativa en pacientes cirróticos
Adrenal insufficiency in cirrhotic patients

Medicina (B.Aires); 76 (4), 2016
La insuficiencia suprarrenal relativa (ISR) es frecuente en pacientes cirróticos con sepsis grave, asociándose a un pobre pronóstico. Se desconoce su importancia en condiciones de enfermedad estable. El objetivo del trabajo ha sido evaluar la prevalencia de la ISR en una serie de pacientes cirróticos...

Characterisation and microleakage of a new hydrophilic fissure sealant - UltraSeal XT® hydro

J. appl. oral sci; 24 (4), 2016
ABSTRACT Objectives The aim of this study was to characterise the new hydrophilic fissure sealant, UltraSeal XT® hydro™ (Ultradent Products, USA), and to investigate its in vitro resistance to microleakage after placement on conventionally acid etched and sequentially lased and acid etched molar...

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...

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...

Aging impairs osteoblast differentiation of mesenchymal stem cells grown on titanium by favoring adipogenesis

J. appl. oral sci; 24 (4), 2016
ABSTRACT Aging negatively affects bone/titanium implant interactions. Our hypothesis is that the unbalance between osteogenesis and adipogenesis induced by aging may be involved in this phenomenon. Objective We investigated the osteoblast and adipocyte differentiation of mesenchymal stem cells (MSCs) f...

Comparison of the marginal adaptation of direct and indirect composite inlay restorations with optical coherence tomography

J. appl. oral sci; 24 (4), 2016
ABSTRACT Objective The purpose of the study was to use the photonic imaging modality of optical coherence tomography (OCT) to compare the marginal adaptation of composite inlays fabricated by direct and indirect techniques. Material and Methods Class II cavities were prepared on 34 extracted human mo...

Effect of silver nanoparticles on the physicochemical and antimicrobial properties of an orthodontic adhesive

J. appl. oral sci; 24 (4), 2016
ABSTRACT Orthodontic treatment with fixed brackets plays a major role on the formation of white spot lesions. Objective This study aimed to incorporate silver nanoparticle solutions (AgNP) in an orthodontic adhesive and evaluate its physicochemical and antimicrobial properties. Material and Methods S...
