Abstract / Excerpt:

These values surprised us, as we had assisted in some observations, made by a Specialist Inspector of Health and Safety Executive, of mercury levels in the breathing zone of dentists following a number of procedures, including the removal of amalgam with high speed drills. These unpublished observations indicate that high levels of mercury vapour can be released during the cutting of cavities in teeth previously filled with amalgam, when minimal aspiration and cooling water are used.  This paper describes some experiments performed to clarify the position and if possible measure and qunatify any exposure to mercury vapour during the preparation and restoration of cavities.
