title: [Bactericidal effects of antiseptic gypsum].
abstract: In tests with plaster models we inspected the antibacterial effect of the dental plasters Dento-rock and Dento-dur. The results show, that models consisting of plaster that contains Chloramin T 80 were free of bacteria, even when produced from bacterial contaminated alginate impressions. After separation of the plaster models from the alginate impressions, a bactericide effect could be traced to a layer of 220 microns below the surface of the alginate. By using dental plaster of the tested types, it is therefore possible to eliminate the risk of a bacterial infection through plaster models, without any extra investing in time or labor. There is no sign of a negative influence of chloramin on physical parameters of the tested plasters.
