This study evaluated biosecurity procedures and management of infectious/sharps waste adopted by 13 dentists and 5 dental assistants in their daily routines in ambulatory care. The data were obtained through a simple observation method, a self-administered questionnaire, and conversations with the subjects under study. Results indicated a complete lack of awareness to biosecurity especially among male dentists and assistants. Most dentists used appropriate personal protective equipment while assistants were apparently unaware of biosecurity practices. Infectious and sharp residues were not disposed of properly and the poor ventilation was a major problem. Despite the fl aws, the work was organised in such a way as to provide professionals with good working conditions. Routine exposure trivialises the occupational risks for dental professionals. Encouraging prevention and security actions can contribute to a healthier and safer workplace.
