Can glass ionomer cements be used as a restorative material?

  1. No

  2. Yes

  3. Only as a temporary measure

  4. Only in pediatric dentistry

The correct answer is: Yes

Glass ionomer cements can be used as a restorative material because they have good adhesive properties and can release fluoride to help prevent tooth decay. Options A, C, and D are incorrect because glass ionomer cements can be used for permanent restorations and not just as a temporary measure or only in pediatric dentistry.
