Objetivo: Cuando las resinas compuestas son expuestas
a procesos de envejecimiento naturales en boca, como es el
ciclaje térmico, pueden sufrir un deterioro en sus propiedades
ópticas. El objetivo de este estudio fue evaluar la influencia
del envejecimiento térmico sobre la estabili...
Aim: This study aimed to evaluate the effect of frozen storage on the physical properties of a silicone-based test food material, highly used to evaluate the masticatory performance in research settings. Methods: A total of 1,666 silicone cubes of Optosil Comfort® with 5.6-mm edges were shaped and store...
RESUMEN: El correcto sellado apical es un paso importante durante el tratamiento de conductos, para esto, se utilizan puntas de gutapercha y cemento sellador, de este último existen diversas formulaciones químicas en el mercado, por lo cual es importante tomar en cuenta los efectos que estas pueden ten...
Neste estudo foram caracterizadas superfícies de titânio (Ti) obtidas após utilização
de diferentes temperaturas pela técnica de implantação iônica por imersão em
plasma de oxigênio (O-IIIP), bem como correlacionado o efeito deste tratamento com
a osteogênese e formação de biofilmes microbi...
Abstract The purpose of the study was to develop a xenogenic bubaline diaphragm matrix (BDM) for abdominal hernia repair. A fresh diaphragm was decellularized using aqueous sodium dodecyl sulfate (SDS) solutions (0.5-4% w/v) over a period. Acellularity was confirmed histologically and characterized by Ma...

Abstract The aim of this study was to evaluate the degree of conversion (DC) and the thermal stability of bulk-fill and conventional composite resins. Eleven composite resin samples were prepared to evaluate the DC, Vickers microhardness (VMH), mass and residue/particle loss, glass transition temperature...
Abstract Objective: To report the results of four mock femoral venous cannulas and the hydrodynamical superiority of one of them, which is the completely punched (CP) model, upon the other three. Methods: Four simulated femoral venous cannulas (single-stage, two-stage, multi-stage, and CP model) were d...
ABSTRACT With the aim of introducing permanent prostheses with main properties equivalent to cortical human bone, Ti-diamond composites were processed through powder metallurgy. Grade 1 titanium and mixtures of Ti powder with 2%, 5% and 10 wt% diamond were compacted at 100MPa, and then sintered at 1250°...
RESUMEN: El propósito del presente estudio fue comparar la degradación de la fuerza entre los elásticos de látex y no látex de 3/16" y 6 oz. La muestra consistió en 30 elásticos por grupo e intervalo de tiempo haciendo un total de 180 elásticos de látex y 180 de no látex. Se midió la fuerza in...
