Effects of Hydrophilicity and Sulcus Width on Sulcus Depth Reproduction.

Abstract

The aim of this in vitro trial was to develop a tree-dimensional sulcus model and to determine effects of hydrophilicity and sulcus width on the sulcus depth reproduction with vinyl polysiloxane impression materials. Regarding single-phase impressions, significant differences were found for sulcus width, 200um > 100um > 50um. Hydrophilicity and their interaction had no significant effect. For double-mix impressions, significant differences were found for hydrophilicity (hydrophilicity > hydrophobic), sulcus width (200um > 100um > 50um), and their interaction.
