Abstract

During the first half of the 20th century, silicates were the only tooth colored aesthetic materials available for cavity restoration. Although, silicates release fluoride, they are no longer used for permanent teeth because of their problems like erosion, brittleness, acidity and a moisture sensitivity which demands very careful manipulation. Latter Self curing acrylic resins were developed in 1930 in Germany, but they too showed poor physical properties like high polymerization shrinkage and coefficient of thermal expansion, lack of wear resistance, poor marginal seal, irritation to pulp and dimensional instability. in an attempt to improve their properties, R Bowen, in 1962 developed ‘composites’. Over the past two decades, there has been a substantial progress in the development and application of resin based composites.
