<prompt> Pure gold has a density of 19.3 gcm3. The apparent density of the direct filling gold restoration after condensation is most often:Equal to 19.3 gcm3More than 19.3 gcm3Less than 19.3 gcm3Can be more or less than 19.3 gcm3  <response>: The maximal density of gold is 19.3 gcm3. 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.
