Dental Restorative Materials Quiz

Study Notes

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.
