The material traditionally used for bonded restorations. Made from an admixture of various glass particles in a polymerized gel-like matrix. This material is generally applied to etched enamel and primed dentin. It is then polymerized with a curing light, a visible blue light which activates a catalyst in the composite and causes it to harden almost instantly. Today's composite bonding materials are extremely esthetic because of the way the glass particles reflect and refract light similarly to natural enamel.
