Vickers microhardness comparison of 4 composite resins with different types of filler.
Composite resins are the material of choice to restore minimal invasive cavities; conversely, it is important to explore the mechanical properties of commercially available dental materials.

Cytotoxicity of Different Composite Resins on Human Gingival Fibroblast Cell Lines
The aim of the present study was to evaluate and compare the cytotoxic effects of eight composite resins on immortalized human gingival fibroblasts. Composite resins were eluted in cell culture medium for 48 or 72 h at 37 °C.

Erosion of Composite Resins [PDF]
The surface degradation of composite resins caused by accelerated aging was studied. Accelerated aging for 900 hours caused erosion of the resin matrices and exposure of filler particles. Differences in surface profiles after aging suggest that the materials eroded at different rates. Accelerated aging may model erosive wear of composites.

Resin composite restorative materials [PDF]
AbstractThis paper surveys the most important developments in resin‐based dental composites and focuses on the deficits (e.g. polymerization shrinkage) and strengths of the materials and their clinical implications. Moreover, differences between composite categories, such as hybrid, nanohybrid, microfilled, packable, ormocer‐based, silorane‐based ...

Surface discoloration of composite resins: Effects of staining and bleaching
Background: The purpose of this in vitro study was to evaluate surface discoloration of three microhybrid composite resins (Esthet·X HD, Clearfil AP-X, Gradia Direct) and five nanohybrid composite resins (Ceram·X, GC Kalore, G-aenial, Grandio, GrandioSO),

The effect of repeated preheating of dimethacrylate and silorane-based composite resins on marginal gap of class V restorations [PDF]
Background. One of the problems with composite resin restorations is gap formation at resin‒tooth interface. The present study evaluated the effect of preheating cycles of silorane- and dimethacrylate-based composite resins on gap formation at the ...
