A number of restorative materials have flooded the markets from time to time. Biocompatibility remains a major concern in the selection of future restorative materials. Autian and his colleagues were amongst some of the first people with publication to evaluate the tissue response of dental materials in 1970's and slowly the concept of biocompatibility were developed. Until a few years ago, almost all national and international dental standards and testing programs focused entirely on physical and chemical properties. Today, however, dental materials standards require biological testing as well. The science of dental materials now encompasses a knowledge and appreciation of certain biological considerations associated with the selection and use of materials designed for use in the oral cavity.
