In most cases, radiographies are used by dentists for the diagnosis and/or treatment of patients, so that they may be considered as a third eye for the dentist. Unfortunately, the radiographic procedures generate certain substances with potential challenge to the environment. Although individual dentists generate only small amounts of environmentally hazardous wastes, the accumulated waste produced by their profession may have a significant environmental impact, which in turn may pose risks to human health. This paper addresses the environmental impact of dental radiographic waste and describes measures that can be taken by dentists and their team to reduce the production of potentially harmful wastes.
