Comparison of the Masking Ability and Translucency of Different Tooth-Colored Restorative Materials.

Purpose: The purpose of this study was to evaluate the masking of simulated silver diamine fluoride (SDF) carious tooth discoloration using tooth-colored restorative materials.

Methods: Eighty disc specimens (N equals 10 disc specimens per group) were prepared using pink opaquer (PO), pink opaquer with composite resin (DUAL), opaque-shade composite resin (OSC), and resin-modified glass ionomer (RMGI) of one-mm and two-mm thicknesses. Three backgrounds were prepared: white, dark dentin shade (C4D), and black tile.
