Objectives: In this study, the hypothesis that the polymerization shrinkage profile of "low shrinkage" non-methacrylate based composite; Silorane and "low shrinkage" high molecular mass methacrylate based composite; Kalore is not different from that of three conventional methacrylate based composites (Gradia Direct X, Filtek Supreme XT and Beautifil II) was tested.
Methods: Five commercially available composites were analysed: one "low shrinkage" non-methacrylate based composite (Silorane); one "low shrinkage" high molecular mass methacrylate based composite (Kalore) and three conventional methacrylate based composites (Gradia Direct X, Filtek Supreme XT and Beautifil II). Polymerization shrinkage was measured using an electromagnetic balance which recorded changes in composite buoyancy occurring due to volumetric changes during polymerization.
