Biological side effects to materials used in dentistry

This review paper outlines the potential adverse reactions that mag. occur through the use of dental materials, Reference is made to documented case reports of side effects. Toxic reactions to permanent dental materials are unlikely., because these materials are developed to be inert and stable and the amount of leachable components is very small. Allergic reactions, on the other hand, are feasible because they may be initiated by minute amounts of the allergen in a sensitised individual. The media in some countries have presented individual patients who allegedly have general symptoms that were relieved by the removal of restorations. ii characterisation of these self-referred patients shows that many of them ha re mental disorders.
