Pure gold has a density of 19.3 g/cm3. The apparent density of the direct filling gold restoration after condensation is most often:
High-Yield Explanation
The maximal density of gold is 19.3 g/cm3. The density values shown in Table indicates the presence of voids in all direct gold restorations. Apparently, voids are inevitable, but they should be kept to a minimum to achieve the maximal strength attainable.
