Effect of microwave disinfection on physical and mechanical properties of acrylic resins
(2008-12-01)
This study evaluated the effect of microwave energy on the hardness, impact strength and flexural strength of the Clássico, Onda-Cryl and QC-20 acrylic resins. Aluminum die were embedded in metallic or plastic flasks with ...
Effect of hydrofluoric acid etching duration on the roughness and flexural strength of a lithium disilicate-based glass ceramic
(2011-05-13)
The aim of this study was to examine the effect of different acid etching times on the surface roughness and flexural strength of a lithium disilicate-based glass ceramic. Ceramic bar-shaped specimens (16 mm x 2 mm x 2 mm) ...
Flexibility and torsional resistance of three nickel-titanium retreatment instrument systems
(2011-08-01)
Aim To assess the dimensional characteristics, flexibility and torsional behaviour of nickel-titanium retreatment instruments. Methodology Using image analysis software and high-resolution digital images, the instrument ...
Influence of thermal and mechanical cycling on the flexural strength of ceramics with titanium or gold alloy frameworks
(2008-03-01)
Objectives: The aim of this study was to evaluate the effect of thermal and mechanical cycling alone or in combination, on the flexural strength of ceramic and metallic frameworks cast in gold alloy or titanium. Methods: ...
Effect of radiotherapy on the radiopacity and flexural strength of a composite resin.
(2008-12-01)
The aim of this study was to evaluate the effect of radiotherapy on the radiopacity and flexural strength of composite resin. Forty Z250 composite resin specimens were polymerized using a halogen light-curing unit and ...
Evaluation of the flexural strength of carbon fiber-, quartz fiber-, and glass fiber-based posts
(2005-03-01)
This study investigated the flexural strength of eight fiber posts (one carbon fiber, one carbon/quartz fiber, one opaque quartz fiber, two translucent quartz fiber, and three glass fiber posts). Eighty fiber posts were ...
Effect of silica coating on flexural strength of fiber posts
(2006-01-01)
Purpose: Fiber-reinforced composite (FRC) posts can be air-abraded to obtain good attachment to the resin cement. This study tested the effect of silica coating on the flexural strength of carbon, opaque, and translucent ...
Flexibilidade anterior do tronco no adolecente após o pico da velocidade de crescimento em estatura
(Sociedade Brasileira de Ortopedia e Traumatologia, 2007-01-01)
Flexibilidade anterior do tronco (FAT) é um componente importante dos exames clínico e de aptidão física utilizado como indicador da função vertebral. O teste mais utilizado para sua quantificação é o sentar-e-alcançar ...
