Evaluation of color stability and surface roughness of smart monochromatic resin composite in comparison to universal resin composites after immersion in staining solutions.

ABSTRACT:

Background

The color stability and surface roughness of resin composites are the primary factors influencing the qualities of restorative materials. This study aimed to assess the color stability and surface roughness of a smart monochromatic resin composite submerged in various staining solutions.

Materials and methods

Ninety-nine disc samples of composite resins (8 mm in diameter and 2 mm in thickness) were prepared and divided into three groups (n = 33): Group A, Omnichroma (Tokuyama Dental, Tokyo, Japan); Group B, Neo Spectra ST HV (Dentsply, Konstanz, Germany); and Group C, Filtek Z350XT (3MESPE) composite resins. The samples were assessed for color stability (M) via a Vita Easyshade spectrophotometer and surface roughness (Ra) with a profilometer before and after therm
