What do GI cements generally contain?

  1. Calcium phosphate

  2. Zinc oxide eugenol

  3. Fluoroaluminosilicate powder and polyacrylic acid

  4. Amalgam

The correct answer is: Fluoroaluminosilicate powder and polyacrylic acid

GI (Glass Ionomer) cements generally contain Fluoroaluminosilicate powder and polyacrylic acid. This is because GI cements are derived from glass and are commonly used in dentistry due to their ability to chemically bond to tooth structure. Therefore, options A, B, and D are incorrect as they do not contain these components that are essential to GI cements. Calcium phosphate, zinc oxide eugenol, and amalgam are common components in other dental materials such as filling materials, bases, liners, and restorative materials. They are not used in GI cements, as they do not meet the properties required for dental cements. Option C is the most suitable as it reflects the composition of GI cements.
