The Developmental history of the dental filling materials

Caries may cause substantial defects in the hard tissue of teeth.The dental filling for de feets is an effective method to resume teeth complete form and masticatory function as well a8 aesthetic effects.The filling material is artificial restorative material to fill the dental defects.Tracing back the devel oping process of dental filling materials,we can see the advancement of stomotology of human beings.There was a revolutionary change in the filling materials from filling dental cavity with Chinese medicinal herbs to silver paste,from establishing the composition and proportion standardization of the silver amalgam filling materials to the application of new macromolecule compound resin.This is a continuous improvement and renewal in the idea and technology of dental filling treatment 80 that perfects the dental filling method and enables the retention of more healthy dental tissue.In addition,it pushes the development of dental aesthet ics,adhesives and technology.With the improvement of people's health standard,aesthetic demands and environmental awareness,compound resin restorative materials has become clinically preferred dental filling materials of doctors and patients in clinic.
