Biohazards associated with materials used in prosthodontics

Abstract

Dental materials for permanent restorations are manufactured with the intent to be stable and insoluble, but they do not fully achieve this goal. The amount of dissolved components is small and their detection sometimes requires sophisticated analytical equipment. The minute amounts of components that leach out of permanent dental restorative materials are most unlikely to cause toxic reactions, locally or systemically. Reliable research information using robust methodology is thus needed to clarify the various safety issues and frequency of adverse reactions in general dentistry,
including prosthodontic treatment.
