6 min read
Asked by: Gina Fanning
The main components of a GIC are glass, polyacid, water and tartaric acid. The composition of the glass can be varied widely, giving many different properties, and, to add to this, there are numerous combinations of polyacids that are suitable for copolymerization.
What are the components of GIC?
There are three essential ingredients to a glass-ionomer cement, namely polymeric water-soluble acid, basic (ion-leachable) glass, and water [4].
What are the components of GIC powder and liquid?
COMPOSITION :
| Powder / Liquid | Contents |
|---|---|
| Powder / Ion Leachable Glass | Silica – 35 – 50 % Alumina – 20 – 30 % NaF – 3 – 6 % AlF3 – 1.5 – 2.5 % Aluminium Phosphate – 4 – 12 % Traces of Barium, Strontium for radioopacity |
What is glass ionomer cement made of?
Glass polyalkenoate cements, more commonly known as glass-ionomers, are made of calcium or strontium alumino-fluoro-silicate glass powder (base) combined with a water soluble polymer (acid). Glass-ionomers were invented in 1969 and reported by Wilson and Kent in the early 1970s.

Is glass ionomer a composite?
Composite fillings are fillings made of resin and other materials such as powdered glass filler. Like glass ionomer fillings, they bond to the tooth, providing additional support to the tooth that traditional fillings (e.g. amalgams) don’t offer.
What is zinc phosphate cement?
Zinc phosphate cement the one of the oldest and widely used cements, and is commonly used for luting permanent metal restorations and as a base. It is a high-strength cement base, mixed from zinc oxide powder and phosphoric acid liquid.
What is composite material in dentistry?
Dental composites, or resin-based composites, are synthetic materials that combine polymeric matrix with a dispersion of glass, mineral, or resin filler particles and/or short fibers by coupling agents. Just like dental amalgam, they are used to restore tooth structure lost through trauma, caries, or other diseases.
What is MTA dental material?
The mineral trioxide aggregate (MTA) is a dental material with biocompatibility properties to oral and dental tissues. MTA was developed for dental root repair in endodontic treatment and it is formulated from commercial Portland cement, combined with bismuth oxide powder for radiopacity.
What is zinc polycarboxylate?
Zinc polycarboxylate cements set by the acid-dissolving part of the zinc oxide particles, which releases zinc, magnesium, and tin ions that bind and crosslink the carboxyl groups. The polyacrylic acid bonds to the zinc ions of the powder and to the calcium ions of the mineralized tooth.
What is composite restoration?
Composite restorations are versatile tooth coloured filling materials composed of strong plastic and glass particles that are used by our dentists or dental therapists to seal deep fissures, fill cavities, and sometimes restore extensively broken down teeth.
What is the difference between Type 1 and Type 2 GIC?
They are fluid materials, also identified as type I, CEM, C or luting. Type II GICs are ionomers indicated for restorations, presenting particles larger than those of type I, also identified as R or FIL, with subtypes 1 and 2.
What is Type 2 glass ionomer cement?
Glass Ionomer Type II is restorative self cured suitable for permanent dental filling. Self-cured. Suitable for permanent dental filling. Chemical setting without shrinkage. Low solubility.
How does GIC bond to tooth?
As a restorative material, GIC bond to the enamel and dentin via ionic and polar bonds, and the intimate molecular contact facilitates ion exchange of fluoride with the hydroxyl ions in the apatite of the surrounding enamel5,39.
What are new modifications of GIC?
These modifications include incorporation of additives (metal, glass, and various nonreactive particles) as fillers in GIC matrix. These initial modifications increased the mechanical properties without having a negative impact on fluoride release capability of the material.
What does luting cement mean?
A luting agent is an application of a dental cement connecting the underlying tooth structure to a fixed prosthesis. To lute means to glue two different structures together.
What is the difference between luting and cementation?
When a crown is cemented, it is luted to the tooth. Luting is defined as packing or sealing a joint in order to make it tight. The connection is purely physical, not chemical.
What is Lute glass?
Dtech Lute Glass GIC Dental Glass Ionomer Cement
Glass Ionomer Luting Cement. Provides excellent adhesion of prosthesis with dentine. Releases fluoride. Low post operative sensitivity.
What is the difference between base and liner?
Liners do not have the sufficient thickness, hardness, or strength to be used alone in a deep cavity, nor should they be used to achieve thermal protection or as a buildup material in a cavity preparation. In comparison, a base not only provides a barrier to chemical irritation, but can also provide thermal insulation.
What materials can be used as a liner?
Varnish, calcium hydroxide, zinc phosphate, glass ionomer, and resin can be used as a liner.
What are cavity liners?
Dental cavity liners have historically been used to protect the pulp from the toxic effects of some dental restorative materials and to prevent the pain of thermal conductivity by placing an insulating layer between restorative material and the remaining tooth structure.
What is the difference between direct and indirect pulp capping?
Pulp capping can be divided in to two categories: indirect pulp capping or direct pulp capping. For an indirect pulp cap, a carious lesion approaches the pulp tissue, but a pulp exposure does not occur. With a direct pulp cap, the pulpal tissue is exposed and a medicament is placed over the exposure.
What is affected dentin?
Affected dentin is firmer than infected dentin due to the presence of the collagen network and some mineral content. Its consistency may be referred to as leatherlike. Healthy dentin is often described as hard dentin or sound dentin.
What is root canal of teeth?
Root canal is a treatment to repair and save a badly damaged or infected tooth instead of removing it. The term “root canal” comes from cleaning of the canals inside a tooth’s root. Decades ago, root canal treatments often were painful.
What material is used for pulp capping?
Two types of pulp-capping materials, calcium hydroxide and mineral trioxide aggregate, have been most commonly used in clinics, and an adhesive resin has been considered a promising capping material.
What is the difference between pulpotomy and pulpectomy?
In pulpotomy, the coronal part of the pulp is removed while in Pulpectomy procedure, the crown and the root canal of the pulp chamber is removed. For further understanding, Pulpotomy is a common procedure and can be referred to as baby root canal. Pulpotomy restores and saves the tooth infected by a deep cavity.
What are the materials used in pulpotomy?
The most frequently used agents are mineral trioxide aggregate (MTA), Biodentine (BD), formocresol (FC), ferric sulphate (FS) and calcium hydroxide (CH).
