Dental MaterialsGoldent is a form of direct gold restoration where pellets of powdered gold are wrapped in a No. 3 gold foil. The foil acts as a container for the gold particles and allows for better handling and condensation during placement. Each pellet contains approximately 95% powdered gold and 5% gold foil, making it more economical than using gold foil alone for restorations.
