Abstract
Restorative materials which come in to close contact with oral tissue should be inert and biocompatible, they should not damage the pulp or soft tissue and should not consist of toxic components which can be absorbed in to the circulatory system and consequently cause toxic and allergic reactions. The fast development of new dental composites has decreased the use of dental amalgam. However, the advantage of dental amalgam is its very good resistance to masticatory forces, simple use in clinical conditions and available price. The disadvantage of amalgam is its unnatural colour, dimensional changes and possible cytotoxicity. Despite excellent aesthetic properties composite degradation depends on the degree of conversion. The longevity of composites is conditioned by homogeneous structure, by the cavity preparation, application of the resin in the cavity, finishing and polishing as well as exhibiting masticatory forces. They are the appropriate solution for reconstruction in the frontal region and also an alternative to amalgam for fillings in the posterior region.
