Summary
Compomers and glass-ionomer cements showed varying solubility and fluoride release over time. Compomers exhibited less corrosion and fluoride leakage compared to ionomers, indicating product-specific material characteristics.
Area of Science:
- Dental Materials Science
- Biomaterials
Background:
- Glass-ionomer cements and compomers are widely used dental restorative materials.
- Understanding their solubility and fluoride release is crucial for clinical longevity and efficacy.
Purpose of the Study:
- To quantify the solubility and fluoride release of glass-ionomer cements and compomers over time.
- To compare the performance of different types of ionomers and compomers.
Main Methods:
- Disk-shaped specimens of three conventional glass-ionomer cements, three hybrid ionomers, and two compomers were prepared.
- Solubility was assessed by measuring mass loss after immersion in lactic acid.
- Fluoride release was measured using a fluoride ion detector in deionized water and buffer solutions.
Main Results:
- Both material type and time significantly influenced solubility and fluoride release.
- Compomers demonstrated lower corrosion and fluoride release compared to ionomers.
- A correlation was observed between solubility and fluoride leakage.
Conclusions:
- Components of both ionomers and compomers can dissolve in aqueous environments.
- The rate and extent of fluoride ion leakage vary significantly between different dental materials.
