Visual and SEM Observations of Resin-Coated Dentin After Taking Impression

Abstract

The resin-coating technique is unique, in which the prepared cavity is sealed with a bonding system and a low viscosity micro-filled resin after cavity preparation, but just before taking an impression. The purpose of this study was to evaluate the influence of impression materials, such as hydrocolloid and silicone rubber (condensation/addition types) on the surface characteristics of resin-coating materials; Protect Liner F and SB Coat. From the results of this study the super fine surface was obtained only with the hydrocolloid impression material. The fine surface was obtained with the condensation type silicone rubber impression material. However, contamination of the resin-coating materials from the addition type silicone rubber impression materials was observed. The surface changes were material dependent. In conclusion, the hydrocolloid impression material is good for use with the resin-coating technique.
