Fuji 9

Fuji IX (often spoken as "Fuji 9") is a highly popular brand of glass ionomer dental cement manufactured by GC America. It is widely used in dentistry as a restorative material for tooth fillings, core build-ups, and long-term temporaries

Because it releases fluoride over time, it is highly valued for its decay-preventing properties and its ability to chemically bond directly to the tooth without the need for additional bonding agents.
