GI contains?

Calcium hydroxide & Zinc oxide
Fluoroaluminosilicate glass & Polyacrylic acid
Methyl methacrylate & Hydroquinone
Ethyl cyanoacrylate & Polymethyl methacrylate

The correct answer is: Fluoroaluminosilicate glass & Polyacrylic acid

GI is a type of dental filling material used to repair cavities. While Calcium Hydroxide and Zinc Oxide (choice A) are used in materials such as intermediate restorative medium and ZOE temporary filling, they are not found in GI. Fluoroaluminosilicate glass (choice B) is commonly found in GI and is light-cured to form a hard and durable filling. Polyacrylic acid (choice B) is used as a liquid component in GI to help with the adhesion of the filling to the tooth. Methyl methacrylate and hydroquinone (choice C) are used in acrylic resin for denture bases, while ethyl cyanoacrylate and polymethyl methacrylate (choice D) are commonly found in dental adhesives. Therefore, choice B is the correct answer as it contains the components typically found in GI.
