title: Marginal porosity of light activated composites in relation to use of intermediate low-viscous resins.
abstract: The marginal porosity of four light activated restoratives (Command, Durafill, Prismafill and Silux) was investigated in extracted human teeth. It was found that the use of a low-viscous resin prior to application of the restorative materials significantly reduced the marginal porosity in both acid etched enamel cavities and EDTA-cleaned dentin cavities.
