Scholarcy highlights

  • Some composite resins fail esthetically because the color differences to adjacent tooth structure are more than the limits of color tolerance
  • The purpose of this study was to assess the effect on color stability of surface-modified dicalcium phosphate anhydrous particles treated with nanocrystallites and silane coupling agents used as fillers for dental composite resin
  • The main color variation was observed within the dried specimens after 24 hours of immersion
  • The color difference stabilized within 8 days
  • Color difference was significantly reduced when the fillers reached a certain proportion, which further indicated that fillers with nanocrystal treatment could stabilize color variations within perceptible color tolerances after immersion and thermocycling
