[The influence of antiseptic solutions used against AIDS on dental waxes, shellac bases, impression compound and zinc-oxide eugenol paste].

The influence of four antiseptic solutions on some dental materials was examined in this study. The antiseptic solutions were sodium chloride 10%, alcohol 75%, Cidex and Sterile pack fluid, whereas the dental materials were dental modelling wax, impression compound, shellac base plate and zinc-oxide eugenol paste. The change of weight and the change of length which were observed in 40 minutes were measured. According to our results the modelling waxes, as well as the impression paste are not influenced by the antiseptic solutions. The impression compound must not be sterilised in Sterile pack fluid, which dissolves it, but it can be floated in the rest of the solutions. The shellac base plates are influenced by all the antiseptic solutions studied, especially by alcohol 75% and Sterile pack fluid.
