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…
Objectives . During its in vivo development, dental bonding is always under polymerization contraction stress (PCS) when there is cure-induced shrinkage and the volume change of restoration is constrained. This…
Objectives . Lucirin-TPO (L) has been introduced in some dental resin composites for aesthetic reasons as well as to increase polymerization efficiency. However, its efficiency and potential use in photoactive…
Objectives . To evaluate the effect of four collagen cross-linking agents, Glutaraldehyde (GD), Grape Seed Extract (GSE), Genipin (GE) and Tannic Acid (TA) on the Reduced Modulus of Elasticity (Er)…
Abstract One often alleges that laboratory bond-strength testing cannot predict clinical effectiveness of adhesives. Major argument to sustain this claim is the wide variation in bond-strength values recorded for one…
