Dentes decíduos bovinos podem substituir os dentes decíduos humanos em testes de resistência de união?
(Universidade Federal de Santa Maria, 2017-07-05)
The evaluation of the performance of adhesive systems in enamel and dentin of primay teeth is justified by the differences in composition and micromorphology of these compared to permanent teeth. The difficulty of obtaining ...
Efeito do jateamento com um novo material a base de alumina revestido por diferentes concentrações de silica na adesão e nas propriedades mecânicas da Y-TZP
(Universidade Federal de Santa Maria, 2018-07-20)
This study is formatted into two parts: the aim of the first study was to evaluate a new approach (Sol-gel approach) to obtain an alternative material for air-abrasion (silica-coated with different concentrations aluminum ...
Adesão à cerâmica Y-TZP: estudo da deposição de nanofilmes à base de sílica na superfície da Y-TZP
(Universidade Federal de Santa Maria, 2013-08-15)
This study in vitro proposed to evaluate the influence of silica-based film coated on the Y-TZP surface on the durability bond strength (BS) between ceramic and resin cement. Eighty Y-TZP blocks (5x5x4 mm) were obtained, ...
Efeito da desinfecção de canais protéticos na resistência adesiva de pinos de fibra de vidro à dentina radicular
(Universidade Federal de Santa Maria, 2011-03-31)
The root canal preparation for placement of endodontical posts, more than
in coronary preparations, produces smear layer rich in remains of dentine, filling
materials and microorganisms, which may decrease the penetration ...
Influência da simulação do desafio cariogênico na resistência de união de sistemas adesivos ao esmalte de dentes decíduos e permanentes
(Universidade Federal de Santa Maria, 2011-03-18)
Objective: The purpose of the present study was to evaluate the influence of the
simulation of cariogenic challenge on bond strength of adhesive systems to sound
and demineralized enamel of primary and permanent teeth. ...
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 ...
Avaliação da evaporação do solvente de sistemas adesivos contemporâneos
(Universidade Federal de Santa Maria, 2012-03-09)
Objectives: The aim of this study was to evaluate the effect of air-drying time on degree of evaporation of solvent (DE), microtensile resin-dentin bond strength (μTBS) and degree of conversion (DC) of adhesive systems.
Methods: ...
Avaliação da resistência de união de diferentes sistemas de cimentação adesiva ao esmalte e a dentina
(Universidade Federal de Santa Maria, 2010-01-21)
Objective: The aim of this study was to evaluate the bond strength to enamel and dentin of a self-adhesive resin cement applied with different cementation strategies,
using a conventional resin cement as control. Material ...
Comparação da resistência de união de sistemas adesivos em diferentes substratos dentinários
(Universidade Federal de Santa Maria, 2015-08-07)
Recently, a new category of adhesive systems has been proposed to perform
restorative procedures. These adhesives, named as universal have been released in the
market with the purpose to decrease the technique sensitivity, ...
Avaliação de tratamentos de superfície da cerâmica YTZP sobre a resistência de união a um cimento resinoso
(Universidade Federal de Santa Maria, 2015-08-03)
This in vitro study was conducted to evaluate the influence of surface
treatments on the bond strength between an yttrium-stabilized tetragonal zirconia
polycrystal (Y-TZP) ceramic and resin cement. For this purpose, 120 ...
