title: [Porosity of composite filling materials].
abstract: The porosity of composite materials was investigated. For the 5 materials tested the values varied between 5.9 and 2.2 vol. %. The volume of porosity could be reduced markedly by a short application of pressure upon the mixed material. Pressure and time of pressure were checked separately, and it could be shown that the percentage of porosity reduction was correlated almost completely with the viscosity of the composite.
