Medical waste management in a dental clinic

摘要

This study investigated how 14 dentists and five dental assistants dealt with the waste produced in a dental clinic of the public health service in the city of Rio de Janeiro. The method of direct observation associated with information obtained through a self-filling questionnaire and interviews with the participants were used. The findings pointed out the improper disposal of biological and sharps waste as well as those from dental amalgams. Only radiological waste received an appropriate treatment. Most health professionals ignored the law posing risks to the public health, environment and their own health. The lack of knowledge concerning the procedures recommended by health authorities is responsible for most of the negligent actions used in dentistry. Knowledge about the importance of the proper disposal of waste should begin in professional training courses.
