This study finds that hygiene practices and inhalation of mercury particulate in dust in the dental office can cause hazards to dental workers. Protective action is recommended.
Abstract / Excerpt:
“The work environment and procedures of twenty-three dentists and their assistants were surveyed for the existence of potential health hazards which could be associated with the preparation of mercury amalgam fillings. Data were collected on the work environment, ventilation, individual procedures, and hazard awareness related to the removal of old amalgam fillings as well as the preparation of new fillings. The results indicated that the greatest potential hazard may result from contamination of hands after working with mercury metal or fresh amalgam. Respirable dust, in terms of total concentration and mercury content, was also significant. This study also demonstrated the almost complete unawareness of most dental assistants and of many dentists that mercury could be hazardous; consequently, precautionary measures were almost nonexistent. A list of recommended precautionary measures is presented.”
