The use of alkoxysilane modified polymers as a silane coupling agent for improving the adhesion between the organic and inorganic phases of a dental composite material was explored. Dental composite materials are typically composed of polymeric diacrylates and silica. The silica is treated with a silane coupling agent to improve the adhesion between the organic and inorganic phases. The diacrylate polymers utilized in this study were an 80:20 (g:g) mixture of bisphenol A diglycidylether methacrylate (Bis-GMA) and triethyleneglycol dimethacrylate (TEGMA). The polymers were doped with a photoinitiator and polymerized using visible light. Ordinary glass slides were used as the silica substrate. Specimens were immersed in water for various periods of time and the adhesion between the substrate and the polymer layer was examined. Comparison between the blank specimens (no coupling agent), a small molecule coupling agent (acryloxypropyltrimethoxysilane), and the polymeric coupling agents will be made.
