Learn what glass ionomer cement is in this article.

Conventional glass ionomer cements are tooth-coloured and available in different shades.

These materials are known as tri-cure glass ionomer cements.

Metal-reinforced glass ionomer cements were first introduced in 1977.

However glass ionomer systems have certain advantages.

Another suggested use of glass ionomer cements is as fissure sealants.

Results from clinical studies also support the use of conventional glass ionomer restorations in primary molars.

Compomers do show a fluoride ion release, like a glass ionomer cement.

Made of aluminum, they are coated with an ionomer foam that resists ultraviolet degradation.

The setting process is glass ionomer (polyalkenoate) cements gives a complex heterogeneous structure.

Glass ionomer cement is a kind of cement used in restorative dentistry.

Whether it is necessary to place protective covering on resin-modified glass ionomer restorations remains controversial.

Other short-term trials also show poor success rates of conventional glass ionomer restorations in primary molars.

Also, because, they only require a short time to fill the cavity, glass ionomer cements present an additional advantage when treating young children.

Alternative materials include composite resins, glass ionomer cements, and gold alloys.

Restorations may be created from a variety of materials, including glass ionomer, amalgam, gold, porcelain, and composite.

What is glass ionomer cement?

Glass ionomer cements bond chemically to dentine and enamel during the setting process.

Nowadays these materials are considered old-fashioned, as the conventional glass ionomer cements have comparable physical properties and far better aesthetics.

Conditioning therefore plays a greater role in achieving effective bonding with the resin-modified glass ionomer cements.

However, the clinical performance of conventional and metal-reinforced glass ionomer restorations in primary molars is disappointing.

It has been shown that ratings in various aesthetic areas are better for compomers than resin modified glass ionomer cements.

A polymer molecule containing ionizable subunits is known as a polyelectrolyte or ionomer.

Polystyrene sulfonic acid is a polymer and ionomer based on polystyrene.

They were introduced in the early 1990s as a hybrid of two other dental materials: dental composites and glass ionomer cement.
