  • Filler, resin, and bonding agent
  • Filler, resin, and silane coupling agent (correct)
  • Water, resin, and silane coupling agent
  • Filler, cement, and silane coupling agent

    • Why is light-cured composite resin preferred over chemical-cured composite resin?

  • Less incremental placement and better strength
  • Decreased water sorption and polymerization shrinkage
  • More color stability and controlled working time (correct)
  • Full-depth curing and increased mechanical properties

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

  • Increases water sorption and mechanical properties
  • Improves color stability and working time
  • Decreases polymerization shrinkage and increases mechanical properties
  • Binds the filler to the resin and decreases water diffusion (correct)
