[Cytotoxicity tests of stomatologic materials on cell cultures]

Authors compare the benefits and drawbacks of agar diffusion tests (with neutral red and with thiazolyl blue) and the filter diffusion test recommended as the standards for cytotoxicity testing of dental materials and their eluates. It seems that there are no differences between these diffusion tests after the treatment for 24 hours. Authors discuss the observed differences in the toxicity between a solid form of the material (ANA 2000 DUO, Evicrol Solar LC) and its eluate.
