Description
Summary:This study was carried out to evaluate the effect of two commercially available chemical disinfectants namely sodium hypochlorite and glutaraldehyde and a surface wetting agent on the wettability of three high precision elastomeric impression materials, addition silicone, condensation silicone and polyether. Three different types of elastomeric impression materials commonly used in prosthodontic practice were selected. The glutaraldehyde and sodium hypochloride solutions were employed to disinfect the impressions made with the above-mentioned elastomeric impression materials. True Blue surface wetting agent was selected. GBX contact angle analyzer was used to measure advancing and receding contact angle. The results of this study have demonstrated that the polyether impression material was the most hydrophilic of all the materials, followed by hydrophilic addition silicone. Condensation silicone was least hydrophilic. All materials showed improvement in the wettability when a topical surfactant was used. The short term disinfection of the three elastomeric impression materials does not affect the wettability of these impression materials.
