which of the following is an advantage to using glass ionomer as a restorative material?
glass ionomer releases fluoride after their final setting
The use of glass ionomer as a restorative material has several advantages such as:
1. Adhesion to tooth structure: Glass ionomer bonds chemically to the tooth structure providing an excellent seal, which helps to prevent further decay.
2. Aesthetics: Glass ionomer restorations can match the natural tooth color and therefore, give a more natural appearance.
3. Fluoride release: Glass ionomer is a fluoride-releasing material, which can help prevent further decay and make the tooth surface more resistant to future decay.
4. Biocompatibility: Glass ionomer is considered biocompatible and non-toxic, making it safe for use in the mouth.
5. Low thermal conductivity: Glass ionomer has a low thermal conductivity compared to metals and other restorative materials. This property reduces the sensitivity of the tooth to temperature changes.
6. Low shrinkage: Glass ionomer restorations have low shrinkage when they set, reducing the risk of cracking or debonding of the restoration.
Overall, the use of glass ionomer for restorative dentistry has many benefits, making it an attractive option for dental practitioners.
