Formulações de fotossensibilizador fenotiazínico contendo etanol ou carreador de oxigênio em diferentes pHs. Efeito antimicrobiano em biofilmes de Pseudomonas aeruginosa
(Universidade Federal de Santa Maria, 2014-08-27)
Our goal was to optimize the antimicrobial photodynamic effect of methylene blue (MB) by adding ethanol or oxygen carrier in the formulation. Pseudomonas aeruginosa PA01 biofilms were formed on acrylic disks for 5 days. ...
Efeito de diferentes tratamentos de superfície na resistência à flexão biaxial e resistência de união entre cimento resinoso e uma cerâmica Y-TZP
(Universidade Federal de Santa Maria, 2016-07-26)
This study evaluated the effect of different surface treatments on the biaxial flexure strength and reliability of a ceramic Y-TZP by using Weibull analysis. In addition, the influence of these methods on the bond strength ...
Comportamento mecânico de uma cerâmica Y-TZP após desgaste com broca diamantada e degradação hidrotérmica
(Universidade Federal de Santa Maria, 2016-07-26)
This study aimed to determine the effects of grinding and low temperature aging on the surface micromorphology (roughness measurement, Scanning Electron Microscopy and Atomic Force Microscopy), phase transformation (t→m), ...
Avaliação da cor de resinas compostas em meios e tempos de armazenamento distintos usando dois espectrofotômetros
(Universidade Federal de Santa Maria, 2011-02-07)
The aim of this study was to evaluate the color of composite resins when stored in water and red wine, during different periods (immediately after polymerization, 24
hours, 30 days and 180 days) comparing the two measurements ...
Efeito do condicionamento de inlays cerâmicas com diferentes concentrações de ácido fluorídrico na carga de fratura sob fadiga de pré-molares restaurados
(Universidade Federal de Santa Maria, 2016-07-26)
The aim of this study was to evaluate the effect of different concentrations of hydrofluoric acid on the fatigue failure load of premolars restored with feldspathic ceramic inlays. Sixty upper premolars were embedded in ...
Efeito do desgaste com instrumentos diamantados e da degradação a baixas temperaturas no comportamento mecânico de uma cerâmica Y-TZP
(Universidade Federal de Santa Maria, 2014-08-05)
Objectives: (1) Compare the effects of grinding on a Y-TZP ceramic executed by
diamond discs and diamond burs (with similar grit sizes) in the micromorphology of
surface, phase transformation (t®m), flexural strength and ...
Efeito do repolimento após clareamento na estabilidade de cor e rugosidade de resinas compostas
(Universidade Federal de Santa Maria, 2016-07-15)
This study aimed to evaluate the effect of repolishing after bleaching on color stability and roughness of two composite resins aged in high staining beverage. Sixty-one disc-shaped specimens (8 mm diameter x 2 mm thickness) ...
