Abstract : Dental acrylic resins routinely used today are radiolucent and cannot be imaged using standard radiographic techniques. A significant number of foreign bodies are dental objects made from acrylic resin and, due to their radiolucency, are difficult to detect and remove. Delays in localizing or removing foreign bodies have lead to many injuries and deaths. Many authors and the American Dental Association have called for the development of radiopaque dental resins. Development of a radiopaque dental acrylic resin would provide an increased margin of safety for many millions of dental patients. The addition of high atomic number elements is required to provide radiopacity to acrylic resins. An acceptable radiopaque additive should be biocompatible and provide a useful level of radiopacity without significantly deteriorating important performance properties. Additives previously tested do not meet all standards of biocompatibility, esthetic requirements and performance properties, including radiopacity. Most additives weaken the resin or produce unesthetic optical properties. Only one acrylic resin with radiopaque properties is currently available in this country (Alikem, - provisional crown and bridge resin) and provides only minimal radiopacity.
