Glass ionomers can serve multiple purposes. Which of the following is NOT one of their uses?

Glass ionomers are versatile materials used in dentistry, known for their ability to bond chemically to the tooth structure and release fluoride. They have several applications, including aesthetic restorations because of their tooth-like color, effective use as liners due to their insulating properties, and their capability to function as bases under dental restorations to provide thermal protection.

The primary reason temporization is not typically associated with glass ionomers is because this term often refers to temporary restorations used during the interim period before a more permanent solution is applied. While glass ionomers can be used in a variety of restorative situations, it is more common to see materials such as resin-based composites or specific provisional materials being designated for temporization due to their quick-setting properties and the aesthetic needs of temporary restorations.

Thus, while glass ionomers serve many productive roles, their use specifically for temporary restorations does not align with their intended applications in more permanent restorative processes.
