Influence of Filler Type and Water Exposure on Flexural Strength of Experimental Composite Resins

Abstract
The objective of this investigation was to determine the influence of water exposure on the flexural strength of three experimental composite materials. The composites consisted of an experimental resin system which contained silane-treated filler particles of quartz, barium glass, and porous silica. The amorphous silica particles were spheres approximately 5 μm in diameter. In addition to the different composites, pure resin samples were investigated as a control group.
