For the purpose of making a comparison between bulk-photo-polymerized resins and composite resins, getting clinically acceptable visible-light cured veneering resins with excellent properties and investigating the effects of two types filters on physical properties of veneering resins, Knoop hardness numbers, compressive and transverse strength of the experimental light cured resins were measured.Knoop hardness numbers of the composite resins were nearly the same characters as bulk-photo-polymerized resins. Physical properties of composite resins were superior to those of bulk-photo-polymeized resins. But characters of polymers were under the influence of curing behavior of monomers. Mechanical properties of composite resins with visible-UV double initiator system stood comparison with those of visible-light cured and heated composites. Compressive strengths obtained from composites with silanized fillet were stronger than those obtained from composites with untreated filler, while the transverse strengths were the opposition. Composites with untreated filler were not water-resistant.
