Influence of pre-heat treatment and different light-curing units on Vickers hardness of a microhybrid composite resin
(2009-06-01)
The aim of this study was to evaluate the hardness of a dental composite resin submitted to temperature changes before photo-activation with two light-curing unite (LCUs). Five samples (4 mm in diameter and 2 mm in thickness) ...
Preparation and characterization of bentonite nanocomposites via sol–gel process
(Springer, 2019-07-22)
Different nanocomposites silica-resin based were prepared and characterized in order to achieve a porous monolith that contains bentonite and allows the flow of aqueous systems. The bentonite used to prepare the nanocomposites ...
Polymerization Shrinkage and Push-out Bond Strength of Different Composite Resins for Sealing the Screw-access Hole on Implant-supported Crowns
(2020-01-01)
Purpose: To evaluate the effect of composite resin polymerization shrinkage stress on the stress distribution in the implant-supported crown-access hole, and on the bond strength between the ceramic and composite resin. ...
Microhardness assessment of different commercial brands of resin composites with different degrees of translucence
(2008-12-01)
Owing to improvements in its mechanical properties and to the availability of shade and translucence resources, resin composite has become one of the most widely used restorative materials in present day Dentistry. The aim ...
