[Microbiological findings on Vikopres paste after functional impressions of the upper jaw].

The microbiological status and disinfecting effect of Vikopres zinc-oxide eugenol paste was investigated after the functional impression was taken. The examinees were persons with edentulous maxilla (n = 32). The silicon paste of similar viscosity applied in the same persons was used as the control. The samples for microbiological tests were taken immediately, 30 minutes later and 3 hours after the impression was made. Significantly less samples with positive bacteriological findings were found on Vikopres paste, compared to the control one.
