E-Z Gold: the new Goldent.
E-Z Gold is a new direct filling gold material that is similar to existing powdered gold formulations but more user-friendly. It is a mixture of pure gold powder and wax (less than 0.01% organic wax), wrapped in gold foil introduced to the dental profession in the late 1980s, and similar metallurgically to gold foil and powdered gold (Goldent) in that, when properly and thoroughly compacted, it has comparable properties: inertness (biocompatibility) and permanence. E-Z Gold's manipulative characteristics are similar to that of a very stiff amalgam, yet more sticky (cohesive) than gold foil, hence the name E-Z Gold. There is no reported research related to physical properties regarding shear, tensile, and cohesive strength. One can assume that E-Z Gold is similar to old Goldent but with improved softness and working characteristics. Clinical experience in the use of this new restorative direct filling gold material has been encouraging. We anticipate that in the near future, clinical and laboratory research comparing this gold to other types of direct filling golds will be forthcoming.
