Properties of microfilled and visible light-cured composite resins. 1979

C N Raptis, and P L Fan, and J M Powers

Physical and mechanical properties of four commercial micro-filled composite resins, a visible light-cured composite resin, and a conventional composite resin were investigated. Isocap, Isopast, and Superfil were similar in most properties. Compared with Concise, they had lower values of inorganic filler content and modulus of elasticity and higher values of water sorption, depth of indentation, and linear coefficient of thermal expansion. The properties of Silar were between those of Concise and the other microfilled composite resins. Fotofil had lower values of modulus of elasticity, water sorption, and linear coefficient of thermal expansion than Concise.
