What type of material is glass ionomer classified under?

Glass ionomer is classified as both a temporary and permanent restorative material due to its unique properties and versatility in dental applications. As a temporary restorative material, glass ionomer can be used to provide a quick and effective solution for patients awaiting more definitive treatment. Its ability to adhere to tooth structure and release fluoride helps in the prevention of further decay, making it suitable for short-term use.

On the other hand, glass ionomer is also recognized as a permanent restorative material. When utilized in areas that will experience low stress and where esthetics may be less of a concern, glass ionomer can effectively restore the tooth structure for an extended period. Its chemical bonding to the dentin and enamel, along with its biocompatibility, supports its use in permanent restorations.

Thus, the classification of glass ionomer as both a temporary and permanent material reflects its adaptability and functionality in various clinical situations, providing dental professionals with a reliable option depending on the needs of the patient.
