Product Features:

A Strontium-based Glass Ionomer: All GC Gold Label Glass Ionomer contains strontium glass. The strontium glass provides good radiopacity and snap set characteristics, unanimously preferred by clinicians around the world. Interestingly, strontium will mimic calcium in the formation of strontium hydroxyapatite and strontium fluorapatite to affect internal remineralization within the tooth structure. Surface Strengthening Effect: Research has shown that a strontium-based glass ionomer placed in a 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 Ionomers 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 that chemically fuses them together. The resulting seal is consistent, predictable, and long-lasting.
