About Glass Cem – Glass Ionomer Powder And Liquid Type 1

Available Quantity : Powder 15g, Liquid 15ml.

Glass ionomer cement (GIC) is a self-adhesive restorative material. Chemically, it is a combination of fluoro – aluminosilicate glass powder and polyacrylic acid liquid. It is a versatile material and has a broad spectrum of uses in restorative and pediatric dentistry.

Composition: Glass ionomer cement is a dental material composed of a powdered glass (silicate glass) and an aqueous solution of an acid, such as polyacrylic acid. The powder and liquid components are mixed to form a cement that can be applied to the teeth.

Setting Mechanism: The setting of glass ionomer cement involves an acid-base reaction. The acid in the liquid component reacts with the glass particles in the powder, resulting in the formation of a hardened matrix. This setting reaction is relatively slow, allowing for easy manipulation and placement of the material in the dental cavity.

Adhesive Properties: One of the significant advantages of glass ionomer cement is its ability to bond to tooth structure. The cement chemically bonds to the tooth’s enamel and dentin, promoting better retention and reducing the risk of microleakage (seepage of fluids and bacteria at the restoration-tooth interface).

Uses in Dentistry:

1. 1. Restorative Material: Glass ionomer cement is commonly used for the restoration of cavities, especially in areas where esthetics is not a primary concern, such as in non-load-bearing regions or in primary teeth.
   2. Luting Agent: It is used as a luting agent for the cementation of crowns, bridges, inlays, and onlays. The adhesive properties help in creating a strong bond between the restoration and the tooth structure.
   3. Base or Liner: Glass ionomer cement can be used as a base or liner under other restorative materials. It releases fluoride, which can be beneficial for preventing secondary caries and promoting remineralization.
   4. Orthodontic Band Cement: It is sometimes used for the cementation of orthodontic bands due to its adhesive properties and fluoride release.
   5. Temporary Restorations: Glass ionomer cement can serve as a temporary restoration when a more permanent restoration is planned.
   6. Fluoride Release: Glass ionomer cements have the advantage of releasing fluoride over time. This fluoride release can contribute to the prevention of secondary caries and enhance the overall oral health of the patient.

Characteristics of GLASS CEM – Glass Ionomer Powder And Liquid Type 1:

1. Adhesion: Glass ionomer cements have good adhesion to tooth structure, providing a chemical bond to enamel and dentin.
2. Fluoride Release: They release fluoride over time, aiding in the prevention of secondary caries and promoting tooth remineralization.
3. Biocompatibility: Glass ionomer cements are generally biocompatible with oral tissues.
4. Easy Manipulation: They have a relatively slow setting time, allowing for easy manipulation and placement in the dental cavity.
5. Esthetics: While not as esthetically pleasing as tooth-colored composite resins, glass ionomer cements are available in tooth-colored formulations for improved appearance in visible areas.
