Can a glass ionomer cement be used as a restorative material?
Can a glass ionomer cement be used as a restorative material?
Glass ionomer cement can be used as a restorative material in its own right or as a base for a composite resin overlay (sandwich restoration) where the remaining tooth structure is unsupported and requires a bonded composite to maintain its structural integrity.
Can glass ionomer be used as a liner?
Varnish, calcium hydroxide, zinc phosphate, glass ionomer, and resin can be used as a liner. Bases are applied in thick layers to provide the pulp with thermal protection. These materials must be strong enough to support a restorative material during placement and function.
Can glass ionomer cement be used as a direct pulp cap?
Glass and resin modified glass ionomer This is due to its superior properties of good biocompatibility and adhesive nature, providing coronal seal to prevent bacteria infiltration. However, they are not a material of choice for direct pulp capping.
Can glass ionomer be used as a luting agent?
Glass ionomer cements have been accepted by many practitioners as reliable luting materials. However, some dentists have condemned them because of frequent postoperative tooth sensitivity and difficult working characteristics.
What are the advantages of glass ionomer cement?
Glass ionomer cements exhibit a number of advantages over other restorative materials. By bonding a restorative material to tooth structure, the cavity is theoretically sealed, protecting the pulp, eliminating secondary caries and preventing leakage at the margins.
Which type of glass ionomer cement is used for pit and fissure sealants?
Type IV is used for pit and fissure sealants. Type V is used in the cementation of orthodontic bands and brackets.
What is the advantage of using glass ionomer cement?
What can be used for direct pulp capping?
Calcium hydroxide remains the “gold standard” for direct pulp capping. It has the longest track record of clinical success, is the most cost-effective and is the likely effective component in MTA. Provide a well-sealed restoration immediately after pulp capping.
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 type of ionomer is used in glass?
Today there are two major types of glassionomers: the water-based which contain freeze-dried acid in the glass powder, and the original, determined by the addition of an aqueous solution of polyacrylic acid to the glass powder.
What is ionomer cement used for in dentistry?
Glass ionomer cement can be used as a restorative material in its own right or as a base for a composite resin overlay (sandwich restoration) where the remaining tooth structure is unsupported and requires a bonded composite to maintain its structural integrity.

How do you mix glass ionomer cements?
Glass-ionomer cements can be mixed using a spatula on a pad or glass block, so-called hand-mixing. The material can also be presented in a bespoke capsule, separated by a membrane. The membrane is broken immediately before mixing, and the capsule is vibrated rapidly in a specially designed auto-mixer.
What are the properties of glass ionomer cement?
Properties of Glass-Ionomers The physical properties of glass-ionomer cements are influenced by how the cement is prepared, including its powder:liquid ratio, the concentration of the polyacid, the particle size of the glass powder and the age of the specimens.
What is the correct name for a glass ionomer?
The proper name for them, according to the International Organization for Standardization, ISO, is “glass polyalkenoate cement” [3], but the term “glass-ionomer” (including the hyphen) is recognised as an acceptable trivial name [4], and is widely used within the dental profession.
