    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
      • Allow for better bonding between the glass ionomer cement and tooth structure
    • Typically, polyacrylic acid is used as the mild dentin conditioner

    Phases of the Setting Reaction

    • The phase involving the release of active ions is characterized by:
      • No change in appearance
    • The phase characterized by a glossy appearance and the ability to adhere to the tooth structure is:
      • The final setting phase
