[Experimental research on the Dacryl-4B material for denture bases]

Comparative investigations of 2 acrylic compounds: Ethacryl and Dacryl-4b are reported. In 240 white rats blood serum lysozyme was studied during 3 days to 6 months. Comparative data evaluation showed that Dacryl-4b had substantially less adverse action on the organism than did Ethacryl. As soon as after 3 months the serum lysozyme levels in experimental group was close to that of sham-operated rats. Encouraging results suggest further investigation into the properties of Dacryl-4b.
