Study Notes
Setting Reaction in Auto-Cure Glass Ionomer Cement
- The setting reaction involves the release of active ions
- This release is a stage of the setting reaction
Components of Glass Ionomer Cement
- Polyacrylic acid attacks the glass particles to release active ions
Purpose of Dentin Conditioning
- Mild dentin conditioning is used in conventional glass ionomer systems to:
- Remove the smear layer and open up dentin tubules
- Allow for better bonding between the glass ionomer cement and tooth structure
Dentin Conditioner
- A mild acid is used as the dentin conditioner
- The dentin conditioner is used to:
- Remove the smear layer and open up dentin tubules
