Abstract
Abstract: A novel dust free alginate impression material was formulated and prepared, comprising
an alginate polyvinylpyrrolidone and tetraflouroethylene resins, a mixture of liquid paraffin and
dimethylpolysiloxane oil as the dust generation controlling agents and processed diatomaceous
earth filler which was obtained from Iranian ore. No dusting was detected during the mixing of the
powder and the conventional properties of the impression material, like working and setting times
and compressive strength were in the range of the required specifications for alginate dental
impressions. The compressive strength was measured to be 2.6 times of the minimum requirement
for such fast setting impressions.
