The aim of this study was to investigate the effect of antagonist material and configuration on combined wear, which was produced by alternating toothbrush wear and simulated occlusal wear on one specimen. Worn volume and maximum worn depth comparisons were done using two antagonist materials (steel and ceramic) and two antagonist configurations (flat and round). For the material factor, worn v...

AIMS Tooth colored dental restorative materials should maintain their chromatic properties throughout their service period. The aim of this study was to examine the possible color changes of flowable resin composite filling materials following water storage. The effect of additional light curing on color stability of restorative materials was also investigated. MATERIALS AND METHODS Six brand...

This report was prepared to provide a comprehensive review of the state-of-the-art for using composite materials for seismic retrofit applications. The emphasis is on seismic retrofit of reinforced concrete columns. The report is presented in eleven chapters. Chapters 1–3 provide a basic introduction to composite materials, including discussions on the types of matrix and reinforcement material...

The aim of this in vitro study was to evaluate and compare the color stability of different esthetic restorative materials (one microfilled composite, one nanofilled composite, one nanoceramic composite, one microfilled hybrid composite, one microfilled hybrid composite, one nanohybrid Ormocer based composite and one supra-nano spherical hybrid composite) after exposure to different staining so...

nanosized metal oxides dispersed polymer composites constitute a fascinating class of polymer composite materials. synthesis of such composite materials through solvent casting enhances the polymer synthetic technology. solvent casting method was used to prepare cobalt oxide (co3o4) dispersed poly (methyl methacrylate) (pmma) nano composite. x-ray diffraction tool is used to know the structural...
