Abstract

The aim of this study was to measure the anti-microbiological effect of the denture cleansers both on polished and non-polished surface six hundred disc shaped polished and non-polished resin specimens, were used. Six different oral microorganisms were selected. Each specimen was then inoculated into the specific medium for cultivation and than removed. Subsequently the media were incubated 24 h at 37°C. After colony counting, contaminated specimens were subgrouped and cleaned with Correga, Protefix, 2% sodium hypochlorite, 2% glutaraldehyde and distilled water. Each specimen was then inoculated into new cultivation medium, after incubation, colonies were recounted in each group. Data were analyzed with Wilcoxon and Mann Whitney U tests. Cleaning efficiency of sodium hypochlorite and glutaraldehyde were better than Correga and Protefix. The latter two agents cleaned polished surfaces better than non-polished. S. aureus was the most adherent microorganism.All the agents except distilled water cleaned polished surfaces effectively but 2% hypochlorite and 2% glutaraldehyde cleaned non-polished surfaces also. Despite of the corrosion and bleaching effects, in need of intense cleaning of resin materials, hypochlorite or glutaraldehyde may be the first choice.

Key words: Denture cleaners, sodium hypochloride, dentures, denture polish, oral microorganisms.
