<p>Introduction: Flowability and hydrophilicity are essential properties of accurate impressions and casts. Aim of study: This study aimed to quantify these characteristics of elastomeric impression materials. Material and Methods: A total number of eight impression materials, including vinyl polysiloxane (PVS), polyether (PE), and condensation silicone (CS) were thoroughly investigated in this study. The flowability of elastomers was proven with the shark fin test (SFT), and the hydrophilicity was determined with contact angle (CA) measurements. Results: The shark fins’ (SF) of VPSs presented 11.57 mm (SD 3.49), while the PE 11.37 mm (SD 5.06) and CS 8.1 mm average values. Some of the products showed better flowability. Based on 128 measured CAs, the examined polyethers had the lowest CAs which indicate good hydrophilicity. Conclusions: A good performance of an impression material in one of the involved tests (SFT and CA) does not mean a similar result in the other analysis. All investigated impression materials could be considered hydrophilic as their CA was lower than 90°. The SFTs of light-bodied VPSs and PEs suggest reliable use of them in dental practice.</p>
