— The levels of methymethacrylate and fromaldehyde in workroom air of a dental laboratory following finishing and polishing a pour type denture base resin have been measured. The levels of these compounds did not exceed the repective hyginic threshold limit values in the general workroom air or in breathing air close to workpice. The centent of asbestos fibers in breathing iair reliased during dismantling molds from gold casting was measured. Durtin the dismanting procedure the fiber content in the air could exceed thresholdlimit values by up to about 12 times. However, About 10 min after terminating this process the fiber content had declined to a level below the esablished requirements.
