The disinfection of dental impression materials has become an essential topic of universal concern, as it may be the first instance of microbial contamination during dental care. The purpose of this study is twofold: To determine the effectiveness of disinfection with 0.5% sodium hypochlorite and 2% glutaraldehyde solutions in irreversible hydrocolloid (alginate) and silicone impressions and to...

wetability of biocompatible polymers can be improved by plasma surface modification. the purpose of this study was to surface modify an experimental poly (dimethylsiloxane) rubber (pdms) material in order to improve its wetability and biocompatibility. surface properties of the pdms were characterized using contact angles measurement for wetability analysis. samples of experimental silicone rub...

This article describes the clinical procedures for a modified putty-wash impression technique. In this method, the hydraulic pressure induced from planned flowing the wash material from the inner surface of putty impression toward the vestibules pull over the gingival tissues covering the finishing line. This simple method reduces the need to using retraction cord in normal depth finishing line...
