Online published on 10 December, 2018. Abstract Developed in 1992 and ADA specification number-92, glass ionomer cement (GIC) (silicate glass powder and an aqueous solution of polyacrylic acid) is widely used as restorative material in conservative dentistry for luting, for restoration (esthetic and reinforced), orthodontic treatment, cavity base, and buildups. While the modified resin GIC, the simplest form of GI cement which contains a small quantity of a water-soluble and polymerized resin component is widely used restorative material and in orthodontic practice also known as traditional GIC. Due to lack of moisture sensitivity, low mechanical strength, and impaired translucency in 1988, resin-modified GI (RMGI) cement were introduced by adding polymerizable hydrophilic resin to CGI (Conventional GI) formulations. Its adhesive nature of getting adhere to both enamel and dentin makes it more attractive to use in orthodontic and in various other branches of dentistry. Orthodontic usage of GIC increased dramatically with the development of resin-modified GIC. These are adhesive cement with improved physical properties and more stable hydrogels compared with GIC. This article critiques the literature to evaluate the cement for its credibility as orthodontic cement, both regarding varied applications as well as physical properties attributed when compared to other commonly used cement available for applications in orthodontic.
