GIC Flashcards
Chelation between the polycarboxylate molecules & Ca ions on the surface of the tooth
Adhesion
First restorative material possessing chemical adhesion/bond to tooth structure
GIC
2 important properties of GIC
- chemical adhesion
- fluoride release
Desiccation of of GIC causes (2)
- shrinkage
- crazing
Setting time of GIC
24 hrs
Lubricant for GIC to prevent crazing
