All GC Gold Label Glass Ionomer contains strontium glass.&The strontium glass provides good radiopacity and snapset& characteristics, unanimously preferred by clinicians around the world. Interestingly, strontium will mimic calcium& in the formation of strontium hydroxyapatite and strontium& fluoroapatite to affect internal& remineralization within the& tooth structure.
Surface Strengthening Effect:
Research has shown that a strontium-based glass ionomer placed in calcium-containing environment (saliva) will result in calcium ion diffusing into the glass ionomer&surface achieving a surface strengthening effect. All GC& Gold Label Glass Ionomer strengthens over time in saliva.
A Consistent Predictable Seal:<
All GC Gold Label Glass Ionomer will display a glossy& surface after mixing. This indicates sufficient free polyacrylic acid is available to begin the ion exchange process. The& subsequent movement of ions between dentin, enamel and& GC Glass Ionomer creates an ion exchange zone which chemically fuses them together. The resulting seal is& consistent, predictable and long lasting.
