Abstract
The aim of this study was to evaluate the microhardness (MS) and surface roughness (SR) of three materials used as surface protectors: Icon® commercial infiltrate (IC), experimental infiltrant (IE) and Prevent resin sealant (SR). Resin disks of the materials (n=120) will be made and then the initial tests of microhardness and roughness will be made. After, they will be divided into 2 subg…
