Comparison of the tensile bond strengths of cast metal crowns luted with resin cements
(Blackwell Publishing, 2004-11-01)
The limitation of photoactivation of dual-polymerized resin cements along the margins of metal restorations may adversely affect the mechanical properties of these cements, thus impairing the retention of restorations. The ...
Effect of thickness of indirect restoration and distance from the light-curing unit tip on the hardness of a dual-cured resin cement
(2010-08-20)
This study evaluated the Knoop hardness and polymerization depth of a dual-cured resin cement, light-activated at different distances through different thicknesses of composite resin. One bovine incisor was embedded in ...
Bonding all-ceramic restorations with two resins cement techniques: A clinical report of three-year follow-up
(2011-10-01)
Ceramics have been widely used for esthetic and functional improvements. The resin cement is the material of choice for bonding ceramics to dental substrate and it can also dictate the final esthetic appearance and strength ...
Fatigue resistance of bovine teeth restored with resin-bonded fiber posts: Effect of post surface conditioning
(2008-01-01)
This study evaluated the effect of post surface conditioning on the fatigue resistance of bovine teeth restored with resin-bonded fiber-reinforced composite (FRC). Root canals of 20 single-rooted bovine teeth (16 mm long) ...
The influence of chemical activation on hardness of dual-curing resin cements.
(2004-07-01)
During the cementation of metallic restorations, the polymerization of dual-curing resin cements depends exclusively on chemical activation. This study evaluated the influence of chemical activation compared with dual-curing ...
Diametral tensile strength of dual-curing resin cements submitted exclusively to autopolymerization.
(2007-10-01)
OBJECTIVES: To evaluate, at different times, the diametral tensile strength (DTS) of dual-curing resin cements that were not photopolymerized. METHOD AND MATERIALS: Equal amounts of base and catalyst pastes of Panavia F ...
The influence of ultrasound on the retention of cast posts cemented with different agents
(2001-03-01)
Aim: The aim of this study was to evaluate the influence of ultrasound during the removal of posts cemented with either zinc phosphate cement, glass ionomer cement or resin cement. Methodology: Eighty-four single-rooted ...
Influence of activation modes on diametral tensile strength of dual-curing resin cements.
(2005-10-01)
In metallic restorations, the polymerization of dual-curing resin cements depends exclusively on chemical activation. The effect of the lack of photoactivation on the strength of these cements has been rarely studied. This ...
Influence of the hybrid layer thickness and resin tag length on microtensile bond strength.
(2011-12-01)
The purpose of this study was to evaluate the correlation between the hybrid layer thickness/resin tag length and the microtensile bond strength of conventional two-step adhesive system, when applied to healthy dentinal ...
