Glass Ionomer Cement

The material properties of glass ionomer determine its excellent clinical performance. Compared with resin-based restorative materials, it releases fluoride ions to prevent secondary caries. It also has better biocompatibility, good edge sealing, and is less prone to postoperative sensitivity problems. It's also easier to clean than resin. Because glass ionomer material does not have high requirements for moisture isolation, it performs well in the restoration of deep caries.
