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 ...
Uso da acrilamida e diferentes protocolos de aplicação de um sistema adesivo universal na resistência de união à dentina
(Universidade Federal de Santa Maria, 2017-07-27)
This study aims to test different adhesive protocols, as well as influence of chemical changes of Single Bond Universal to verify improvement in bond strength and stability of the hybrid layer. One hundred and forty-four ...
Performance in vitro e in vivo de sistemas adesivos universais em diferentes estratégias de condicionamento da dentina
(Universidade Federal de Santa Maria, 2019-08-05)
The new generation of adhesive systems, called as "universal adhesives" or "multi-mode",
are adhesives which can be used in both self-etch (SE) or etch-and-rinse (ER) strategies.
Two studies related to these materials ...
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 ...
Resistência de união de sistemas adesivos em dentina previamente exposta a materiais contendo eugenol
(Universidade Federal de Santa Maria, 2020-08-31)
Zinc oxide-eugenol cement (ZOE) is still a reality in clinical practice. Eugenol present in cement affects
the polymerization of monomers, such as those found in adhesive systems. Previous studies have
shown divergence ...
Resistência de união de sistemas adesivos atuais em dentina submetida a diferentes tratamentos
(Universidade Federal de Santa Maria, 2010-12-17)
Studies have shown that the longevity of adhesive restorations is adversely affected by collagen degradation. The purpose of this study was to evaluate the effect of different treatments on the bond strength of adhesive ...

(Universidade Federal de Santa Maria, 2010-02-24)
The aim of this study was to evaluate the thickness of hybrid layer and the depth of demineralization produced by adhesive systems applied in dentinal surfaces submitted to
different treatments. Dentin slices extracted ...
Efeitos do pré-tratamento dentinário e temperatura do adesivo na resistência adesiva de um sistema adesivo universal
(Universidade Federal de Santa Maria, 2016-07-28)
This study aimed to evaluate the effects of dentin pretreatment and temperature on the bond strength of a universal adhesive system to dentin. Ninety-six extracted non-carious human third molars were randomly divided into ...
Avaliação da influência de diferentes métodos de aumento de temperatura na resistência de união de um sistema adesivo de condicionamento ácido total.
(Universidade Federal de Santa Maria, 2013-07-26)
Purpose: Different methodology of adhesion have been tested in order to promote better bonding strength between dentinal substrate and composite resin. The increase of temperature associated with the solvent evaporation, ...
