Objectives . Photo-iniferters are molecules capable of initiation, chain transfer and termination reactions, suitable to produce controlled radical photo-polymerizations, which can be useful, for example, when thermal stability is desired….
Objectives . The purpose of this study was to evaluate the change of gloss for nanocomposite resins by toothbrushing. Materials and methods . Nine different composite resins were filled into…
Objective . The elastic modulus (EM) is the main constant characterizing the stiffness of a solid material. Different methods are known to describe this parameter, as there are mechanical (static…
Objectives . In this paper, a non-destructive testing technique – acoustic emission (AE) – was used to monitor the development of micro-debonding in a dental restoration during the polymerization of…
Objectives . The purpose of this study was to investigate, in dental neat resins, the effect of adding hyperbranched polymers (HBPs) on polymerization contraction ( C ), degree of conversion…
Objectives . To evaluate the effect of instrument compliance on the polymerization shrinkage stress measurements of dental composites. Materials and methods . The contraction strain and stress of composites during…
Objectives . Shrinkage stress is still considered to be a major drawback of resin-based composite materials. It was claimed that resin systems based on the SDR™ technology (Stress Decreasing Resin)…
Objectives . The aim of this study was to examine microleakage at the interface between pit-and-fissure sealants and enamel using micro-CT. Materials and methods . Six extracted intact human molars…
Objectives . Assess patterns of clinical change observed from USPHS direct evaluation categories for pooled results of 10 clinical trials for Class I and II posterior composite restorations monitored up…
Introduction . Recently, composites contaning monomers alternative to conventional dimetacrylates appeared on the market. According to the manufacturers, these new composites show lower volumetric shrinkage, which would lead to lower…
