What are the main components of composite resin?
What are the main components of composite resin?
- 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?
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?
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)
