Dental Restorative Materials Quiz

Type II (Restorative) Glass Ionomer Cement Indications

• Used primarily for filling cavities in non-load-bearing areas.
• Suitable for use in areas where aesthetics is not a primary concern due to its opacity.
• Often indicated for use in pediatric dentistry and temporary restorations.

Setting Reaction of Glass Ionomer Cement

• Comprises an acid-base reaction between glass particles and polyacrylic acid.
• Involves the release of fluoride during the setting process, providing caries resistance.
• The reaction leads to the formation of a gel-like structure that hardens over time.

Types of Glass Ionomer Cement for Luting

• Type I Glass Ionomer Cement is specifically used for luting.
• Provides a strong bond to both the tooth structure and restorative materials.
• Ideal for cementing crowns, bridges, and orthodontic appliances.

Role of Tartaric Acid in Glass Ionomer Cement

• Added to modify the setting characteristics of the cement.
• Helps to prolong the working time, allowing for better manipulation during application.
• Enhances the strength and handling properties of the final set material.

Composition of Conventional Glass Ionomer Cement

• Composed of finely ground glass particles, usually silica with fluorine ions.
• Mixed with polyacrylic acid to facilitate the acid-base reaction.
• Additionally includes water and tartaric acid to enhance specific properties.

Acid Added to Conventional Glass Ionomer Cement

• The addition of tartaric acid aids in improving handling.
• Extends the working time, decreases setting time, and enhances shelf life.
• Results in a more user-friendly product for dental professionals.
