Effect of different composite core materials on fracture resistance of endodontically treated teeth restored with FRC posts

J. appl. oral sci; 25 (2), 2017
Abstract Objective This study evaluated the fracture resistance of endodontically treated teeth restored with fiber reinforced composite posts, using three resin composite core build-up materials, (Clearfil Photo Core (CPC), MultiCore Flow (MCF), and LuxaCore Z-Dual (LCZ)), and a nanohybrid composite, ...

Human DNA extraction from whole saliva that was fresh or stored for 3, 6 or 12 months using five different protocols

J. appl. oral sci; 25 (2), 2017
Abstract Saliva when compared to blood collection has the following advantages: it requires no specialized personnel for collection, allows for remote collection by the patient, is painless, well accepted by participants, has decreased risks of disease transmission, does not clot, can be frozen before DN...

Effects of radiant exposure values using second and third generation light curing units on the degree of conversion of a lucirin-based resin composite

J. appl. oral sci; 25 (2), 2017
Abstract Alternative photoinitiators with different absorption wavelengths have been used in resin composites (RCs), so it is crucial to evaluate the effectiveness of light-curing units (LCUs) on these products. Objective Using Fourier transform infrared analysis (FTIR) in vitro, the effects of varying...

Periodontitis and type 2 diabetes among women with previous gestational diabetes: epidemiological and immunological aspects in a follow-up of three years

J. appl. oral sci; 25 (2), 2017
Abstract Periodontitis can contribute to the development of insulin resistance. Gestational diabetes is a risk factor for type 2 diabetes. Therefore, periodontitis, when associated with gestational diabetes, could increase the risk for the development of type 2 diabetes after pregnancy. Objective The a...

Triazine Compound as Copolymerized Antibacterial Agent in Adhesive Resins

Braz. dent. j; 28 (2), 2017
Abstract The aim of this study was to formulate and evaluate an experimental adhesive resin with the addition of 1,3,5-triacryloylhexahydro-1,3,5-triazine at different concentrations. Experimental adhesive resins were obtained by mixing 50% wt bisphenol A glycol dimethacrylate (BisGMA), 25% wt triethylen...

Effect of Metal Primers on Bond Strength of a Composite Resin to Nickel-Chrome Metal Alloy

Braz. dent. j; 28 (2), 2017
Abstract This study evaluated the effects of three metal primers and one multi-mode adhesive system on the shear bond strength (SBS) of a flowable composite resin to nickel-chrome metal alloy (Ni-Cr). Ninety plates were cast from Ni-Cr and divided in nine groups (n=10). The surfaces were sandblasted with...

Evaluación biomecánica del efecto de bisfosfonatos y aceite de oliva en un modelo de remodelación óseo en fémur de rata: efectos en la remodelación ósea

Estudios han demostrado que el aceite de oliva (O) con sus compuestos fenólicos tienen efectos positivos en diversos biomarcadores fisiológicos. Análisis previos han demostrado que los bisfosfonatos, son potentes inhibidores de la resorción ósea. Estudiar el efecto del tratamiento combinado de alend...

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...

Sucrose induced dentin demineralization in a microcosm biofilm model

The aim of this in vitro study was to assess the root dentin demineralization caused by a microcosm biofilm model that has been exposed to sucrose in different ways. Materials and Methods: Saliva of two volunteers was inoculated into an artificial medium for biofilm growth and dentin blocks were immersed...

Quality of bevacizumab (Avastin®) repacked in single-use glass vials for intravitreal administration

Arq. bras. oftalmol; 80 (2), 2017
ABSTRACT Purpose: Avastin® (bevacizumab) is an anti-vascular endothelial growth factor (VEGF) monoclonal antibody given as an off-label drug by intravitreal administration for treatment of ocular diseases. The drug's clinical application and its cost-benefit profile has generated demand for its divisio...
