[The antimicrobial effect of an alginate with an antiseptic admixture].

Attempts to simplify impression disinfection lead to the production of an aseptic alginate impression material (Blueprint asept, De Trey/Dentsply, Konstanz, Germany). This study describes the aseptic properties of this new type of impression material. The in-vitro part of the experiments showed a reduction of Staphylococcus aureus by 6 and of Pseudomonas aeruginosa by 4 log steps after 60 min, and of Candida albicans by at least 3 log steps after 15 min of exposure. Under in-vivo conditions oral bacteria residing on the impression surfaces were reduced by nearly 4 log steps. Although the aseptic properties of the material were demonstrated, the biological acceptance, dimensional stability and compatibility with gypsum have to be tested in further studies.
