Abstract The aim of this study was to determine the influence of photoinitiator systems on physical-chemical properties of flowable composites. Conventional (CFC), composed by bisphenol-glycidyl dimethacrylate (BisGMA)+triethyleneglycol dimethacrylate (TEGDMA), and self-adhesive (SAFC), composed by BisGM...
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...
Abstract The aim of this study was to assess the effects of intracanal irrigation with sodium hypochlorite (NaOCl) and ethylenediaminetetracetic acid (EDTA) prior to calcium hydroxide medication on the compressive strength of root dentin. Forty-eight roots with single and straight canals were instrumente...
Abstract The aim was to evaluate the surface roughness and bacterial adhesion on enamel irradiated with high intensity lasers, associated or not to a fluoride varnish. Eighty fragments of bovine enamel were equally divided in 8 groups (n=10). Group 1 was not treated and Group 2 received only a 5% fluorid...
Abstract The aim of this study was to evaluate the μTBS in different dentin substrates and water-storage periods. Twenty-four dentin blocks obtained from sound third molars were randomly divided into 3 groups: Sound dentin (Sd), Caries-affected dentin (Ca) and Caries-infected dentin (Ci). Dentin blo...
ABSTRACT Objective: The present in vitro study evaluated, by means of the photoelastic technique, the effects generated by the Connecticut Intrusion Arch (CIA), with a 90o bend on the distal surface of molar tubes and using the 4 x 2 appliance on the anterior and posterior regions of the upper dental a...
Summary Autophagy is a survival pathway wherein non-functional proteins and organelles are degraded in lysosomes for recycling and energy production. Therefore, autophagy is fundamental for the maintenance of cell viability, acting as a quality control process that prevents the accumulation of unnecessar...
Introdução: Doenças cardiovasculares constituem importante causa de morte em todo mundo e a hipercolesterolemia está diretamente relacionada a este problema de saúde pública. A dieta desempenha papel importante neste processo e alguns alimentos, como o amaranto (Amaranthus cruentus L. BRSAlegria), ...
La caries dental se la define como una patología universal y de múltiples factores que se caracteriza por la disolución localizada y química de los tejidos duros de las piezas dentales por la acción de ácidos orgánicos, resultado del metabolismo fermentativo de azúcares de las bacterias. Existen ...
La planta de coco (Cocos nucifera L) llamada el árbol de la vida, se encuentra en los primeros lugares de las especies de plantas alimenticias vitales para el hombre; debido a las múltiples propiedades que posee es que se planteó la presente investigación con el objetivo fundamental de determinar el ...
