Question

The cement that gives off an exothermic reaction and must be spatulated over a wide area of a cool, dry, thick glass slab is: A) Glass ionomer cement B) Zinc phosphate cement C) Composite resin cement D) Polycarboxylate cement

Answer 1

The cement that gives off an exothermic reaction and must be spatulated over a wide area of a cool, dry, thick glass slab is Zinc phosphate cement.

Step-by-step explanation:

The cement that gives off an exothermic reaction and must be spatulated over a wide area of a cool, dry, thick glass slab is Zinc phosphate cement.

When zinc phosphate cement is mixed, it undergoes a chemical reaction that releases heat, making it exothermic. It is necessary to spatulate zinc phosphate cement over a wide area to dissipate the heat generated during the reaction. This cement is commonly used in dentistry for cementing various dental restorations.
