Setting Stress in Composite Resin in Relation to Configuration of the Restoration
It was shown that in most of the clinically relevant cavity configurations, the stress-relieving flow is not sufficient to preserve adhesion to dentin by dentin-bonding agents. Expand
Microtensile bond strength of different components of core veneered all-ceramic restorations. Part II: Zirconia veneering ceramics.
Selecting stronger veneer ceramics which have good bond strength with zirconia can reduce the chances of chipping and delamination under function and the liner material should only be used with some layering veneers but not in combination with pressable veneering as it will result in weakening of the microtensile bond strength. Expand
Polymerization shrinkage and polymerization shrinkage stress in polymer-based restoratives.
The dimensional changes which develop during the curing of resin composites and glass polyalkenoate cements are studied, with special reference to methods of determining shrinkage, shrinkage stress and stress relief. Expand
Microtensile bond strength of different components of core veneered all-ceramic restorations.
The core-veneer bond strength is one of the weakest links of layered all-ceramic restorations and has a significant role in their success and further research work is needed to improve its bond with its corresponding veneering material. Expand
Selective infiltration-etching technique for a strong and durable bond of resin cements to zirconia-based materials.
For the materials used in this study and under the same testing conditions, selective infiltration etching is a reliable method for establishing a strong and durable bond with zirconia-based materials. Expand
Effect of zirconia type on its bond strength with different veneer ceramics.
To prevent delamination and chipping failures of zirconia veneered restorations, careful selection of both framework and veneer ceramic materials, in addition to proper surface treatment, are essential for maintaining good bond strength. Expand
Mechanical properties of glass ionomer cements affected by curing methods.
An increase in strength was found, especially at the early curing time, which can improve the survival rate of GICs in the clinical situation and Ultrasonic excitation can be used as a 'command' set method and improves the properties of G IC at early setting time. Expand

This study shows that the unpolymerized resin content determines the amount of shrinkage, contraction stress and tensile modules, therefore, using pre-polymerized clusters will improve shrinkage/contraction stress properties, as was shown in Heliomolar, while high polymerization rates, and low flow factors have a deteriorative effect on the shrinkage / contraction stress properties.

Polymerization contraction stress in thin resin composite layers as a function of layer thickness.
A measuring method was developed which was found to be suitable for the determination of axial polymerization contraction stress in this films of chemically initiated resin composites and makes it possible to estimate the stress levels that occur in resin composite films in the clinical situation. Expand
The influence of porcelain layer thickness on the final shade of ceramic restorations.
It is indicated that small changes in OP/TP thickness ratio can perceivably influence the final shade of the layered specimens (DeltaE>1) and redness a* and yellowness b* increased with the thickness of OP for all shades. Expand
