  Objective: The purpose of this study was to evaluate the wettability of commercial Vinyl Polysiloxane (VPS) impression materials by measuring contact angles on horizontal and non-horizontal surfaces using artificial saliva. Materials and Methods: Three light bodies (Affinis (Affi); Silagum (Sila) and Variotime (Vario-LB)) and one extra light body (Viriotime (Vario-ELB)) impression materials were used to fabricate specimens with flat surfaces. Static and dynamic contact angles were measured using the sessile drop method (OCA-20 contact angle analyzer) as a function of time. Contact angle hysteresis shown was advancing minus receding contact angles. All data were analyzed by one-way ANOVA and Games-Howell post hoc test (p<0.05). Results: The static and dynamic contact angles of all tested impression mat.. View More»
