Glass ionomer cement (GIC) is one of the materials used in the field of dentistry as a filling material. This binding material is also known as dental cement. It also finds application in the luting process. It is commonly used in restoration and repair of teeth, filling cavities, and as a
A glass ionomer cement (GIC) is a dental restorative material used in dentistry as a filling material and luting cement, including for orthodontic bracket attachment. Glass-ionomer cements are based on the reaction of silicate glass-powder (calciumaluminofluorosilicate glass ) and polyacrylic acid, an ionomer. Occasionally water is used instead of an acid, altering the properties of the material and its uses. This reaction produces a powdered cement of glass particles surrounded by matrix of fluorideelements and is known
5.8 Glass-ionomer cement restorations. Glass-ionomer cement (GIC) are favored restorative materials owing to their ease of use and unique biocompatibility, attributable to their good adhesion (Yip et al., 2001). Leakage appears to be largely prevented and, thus, invasion of bacteria at the tooth-filling interface is minimized.

Introduction. Glass ionomer cement (GIC) has been widely used in dentistry since 1970. 1,2 It is considered superior to other types of water based cements because it has good mechanical properties and transparency. 3 In addition, fluoride release over a prolonged period and good biocompatibility make GIC useful as a dental material. 4 However, GIC has some disadvantages such as relatively high
New glass ionomer cement with improved physical and aesthetic properties that makes it the material of choice for class III, V and root surface restorations. but the hardening process is derived from the slower formation of aluminium polyacrylate . This phase ultimately predominates in the mixture.
