The selection of cement for a specific procedure requires knowledge of the chemical and physical properties of each particular cement for the specific restorative process to be performed. This first cement I’m going to discuss is Glass Ionomer Cement. Glass ionomer cement is one of the most versatile types of cement in the dental field. This is a hybrid type of silicate and polycarboxylate cements. This adheres to the enamel, dentin, and metallic materials. They are supplied in 3 different types, type I, type II, and type III.

And Type III is used as a liner dentin bonding agent. Glass ionomer has benefits such as it causes less trauma to the pulp; it has low solubility in the mouth, and adheres to a slightly moist tooth surface, etc. The chemical makeup includes a liquid made of polyacrylic acid copolymer and water while the powder is made of calcium fluoroaluminosilicate glass with barium glass. It is available in light-curing or self-curing formulas. It is supplied in bottles of powder or liquid which can be mixed manually paper pad or a glass slab, as well as in premeasured capsules for expressing through a dispenser. The second type of cement is Composite Resin Cement. Composite resin is a newer cement consisting of composite resin cement. It is especially designed for ceramic or porcelain inlays, onlays, crowns, and bridges, ceramic veneers, orthodontic bands, direct bonding or orthodontic brackets, and metal-based crowns and bridges. It has physical properties as those of composite resin such as a thin film thickness...
