Questions and Answers

What is the function of the silane coupling agent in composite resin?

  • Decreases water diffusion between filler and resin
  • Increases water sorption
  • Binds the filler to the resin (correct)
  • Decreases mechanical properties
  • What is the depth of curing for light-cured composite resin?

  • 3 mm
  • 1 mm
  • 4 mm
  • 2 mm (correct)
  • Why is light-cured composite resin preferred over chemical-cured composite resin?

  • It has full-depth curing
  • It has a controlled working time
  • It has more color stability (correct)
  • It decreases water sorption
  • Study Notes

    Composite Resin

    • Silane coupling agent is used to enhance the bonding between the filler particles and the resin matrix, increasing the mechanical strength and durability of the composite resin.
    • The depth of curing for light-cured composite resin is typically up to 2-5 mm, depending on the type of resin and the intensity of the light source.
    • Light-cured composite resin is preferred over chemical-cured composite resin because it allows for faster curing times, reduced shrinkage, and improved color stability, making it a more convenient and aesthetically pleasing option for dental restorations.
