Color-matching according to the use of light-curing characterizing materials and composite resin thicknesses
This study aimed to evaluate the ability of light-curing characterizing material sand two thicknesses of composite dentin resin on masking differents dark substrates. 320 composite resin specimens were divided into 6 experimental groups (n=50), which were divided into 5 subgroups (n=10) according to the different characterizing material sand resin coverage thicknesses; and 2 control groups (n=10). The darkened bases were made in laboratory composite resin, in colors DA4, DB4 and DC4.
