title: Levels of airborne particles resulting from handling alginate impression material.
abstract: The levels of airborne particles emanating from handling alginate impression powders have been surveyed. The concentrations of powders, lead and silicious particles in the aerosol have been measured after thoroughly shaking the containers before opening. The decrease of the powder concentration in the ambient air as a function of time has been estimated. The efficiency of face masks to protect against powder exposure has been investigated.
