      Purpose: The purpose of this in vitro study was to compare color stability and surface roughness of different tooth-colored restorative materials commonly used in pediatric dentistry after prolonged immersion into grape juice. Methods: Forty disc specimens were prepared using pink opaquer (PO), pink opaquer with composite resin (DUAL), composite resin (COMP), and resin-modified glass ionomer (RMGI) of two-mm thickness. 3D-printed wells were fabricated in CD4 shade. After specimens were placed into the wells and the margin was sealed, specimens were immersed in grape juice. Color and surface roughness were measured at baseline, 24 hours, one week, and four weeks. Color measurements were made using a Vita Easyshade ® spectrophotometer. A contact-type profilometer was used for surface roughness measurements. Results: There was a significant difference in color stability and surface roughness among the materials used (one-way analysis of variance, P<0.001) from baseline to 24 hours, one week, and four weeks in the following order: ΔE for PO (3.79)
