Effect of accelerated aging on the microhardness and color stability of flexible resins for dentures
(2010-01-01)
Acrylic resins have been widely used due to their acceptable esthetics and desirable characteristics such as easy handling, good thermal conductivity, low permeability to oral fluids and color stability. Flexible resins ...
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 ...

Optical characterization of one dental composite resin using bovine enamel as reinforcing filler
(2012-06-12)
The use of composite resins for restorative procedure in anterior and posterior cavities is highly common in Dentistry due to its mechanical and aesthetic properties that are compatible with the remaining dental structure. ...

Effect of Surface Treatments on the Bond Strength between Composite Resin and Acrylic Resin Denture Teeth
(2000-12-01)
Purpose: This investigation studied the effects of 3 surface treatments on the shear bond strength of a light-activated composite resin bonded to acrylic resin denture teeth. Materials and Methods: The occlusal surfaces ...

First purification of heparan sulfate disaccharides with an amine resin used as solid support for peptide synthesis
(Elsevier B.V., 2000-01-03)
For the first time, highly substituted benzhydryramine-resin (BHAR), a solid support used only for the peptide synthesis method was assayed successfully as an anion exchanger resin for fractionation of (-2)-, (-3)- and ...
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 ...
Bonding strength between a hard chairside reline resin and a denture base material as influenced by surface treatment
(Blackwell Publishing, 2001-12-01)
Direct relining of dentures made with hard chairside reline resins is faster than laboratory-processed reline systems and the patient is not without the prosthesis for the time necessary to perform the laboratory procedures. ...
