Visible light-cured and chemically-cured composite resins showed varying color stability. Photocured resins demonstrated better color stability when stored in water, while UV light caused significant color changes across brands.

Area of Science:

  • Dental Materials Science
  • Polymer Chemistry
  • Color Science

Background:

  • Composite resins are widely used dental restorative materials.
  • Color stability is a critical aesthetic and clinical performance factor.
  • Exposure to environmental factors like UV light and moisture can affect resin color.

Purpose of the Study:

  • To investigate the color stability of visible light-cured and chemically-cured composite resins.
  • To evaluate the impact of UV light irradiation and aqueous storage at elevated temperatures on resin color.

Main Methods:

  • Seven visible light-cured and three chemically-cured composite resins were tested.
  • Specimens were subjected to UV light irradiation and storage in water at 37°C.
  • Color change was assessed using both visual evaluation and colorimetric measurements.

Main Results:

  • A significant correlation was observed between visual color assessment and colorimetric data.
  • Photocured composite resins exhibited considerable brand-to-brand variation in color change under UV light.
  • Chemically-cured resins showed less color shift than photocured resins under UV light but within a similar range.
  • Photocured resins displayed superior color stability compared to chemically-cured resins when stored in water at elevated temperatures.

Conclusions:

  • Composite resin color stability is influenced by curing method and environmental exposure.
  • Photocured resins offer better color stability in aqueous, elevated temperature conditions.
  • UV light exposure can induce significant color alterations in visible light-cured composite resins, with notable inter-brand differences.
