Abstract Non-silicate ceramics, especially zirconia, have become a topic of great interest in the field of prosthetic and implant dentistry. A clinical problem with use of zirconia-based components is the…
Abstract Objectives : The aim of this study was to explore the therapeutic opportunities of each step of 3-step etch-and-rinse adhesives. Methods : Etch-and-rinse adhesive systems are the oldest of…
Abstract It is important to clarify the potential response of different types of cells to different implant materials and topographies. Thus, in vitro studies are performed using cell cultures, in…
Abstract Light curing in dentistry has truly revolutionized the practice of this art and science. With the exception bonding to tooth structure, there is perhaps no single advancement that has…
Abstract This paper reflects on the state of the art of self-etch adhesives anno 2010. After presenting the general characteristics of self-etch adhesives, the major shortcomings of the most simple-to-use…
Abstract Objective The use of a 30 μm alumina–silica coated particle sand (CoJet™ Sand, 3M Espe), has shown to enhance the adhesion of resin cements to Y-TZP. The question is…
Abstract Objectives To measure the ‘repair’ strength of various combinations of composite using four manufacturers’ adhesive systems, to compare the bond strengths with the cohesive strength of the original, unrepaired…
Abstract Objectives To investigate the kinetic process of water diffusion and mass change in new resin–matrix composites during water sorption/desorption cycles. Methods Five new resin–matrix composites were investigated [Filtek ®…
Abstract Objectives The purpose of this study was to validate a new laboratory method to test all-ceramic systems with regard to the proportion of failures. Methods Sixteen standardized mandibular molar…
Abstract Objective The purpose of the present study was to submit the same materials that were tested in the round robin wear test of 2002/2003 to the Alabama wear method….
Abstract Objectives Application of acidulated phosphate fluoride (APF) gels has long been considered to cause deterioration of composite surfaces. The aims of this study were to demonstrate that nanocomposite surfaces…
Abstract Objectives The aims of this study were to evaluate the cytotoxicity of four orthodontic primers, including two hydrophilic and two hydrophobic materials, and to investigate the role of the…
Abstract Objective To investigate the surface integrity of solvent-challenged ormocer-matrix composites, photoactivated by different light exposure modes, through surface-hardness measurements at different periods of time; and to compare such behavior…
Abstract Objectives The study was conducted to compare the optical parameters of VM7 ® M-shade base dentin ceramics (VITA, Germany) for all ceramic restorations to the chemical composition across the…
Abstract Objectives To test the influence of photoinitiator type and filler particle inclusion on the validity of exposure reciprocity law. Materials and methods 50/50 wt% Bis-GMA/TEGDMA resins were prepared with…
Abstract Objective The objective of this prospective clinical follow up was to evaluate the long term clinical performance of a hybrid resin composite in Class II restorations with and without…
Abstract Objectives Aim of the study was the investigation of the repairability of a silorane (Filtek Silorane, 3M Espe, Seefeld, Germany) after different surface pretreatments in vitro . Methods 54…
Abstract Objectives To analyze the influence of cavity geometry and lining materials in MOD composite restorations by characterizing the polymerization shrinkage and cusp deflection. Methods Eighty intact molars with similar…
Abstract Objective Restorative materials exhibit contraction and expansion due to polymerization and water absorption. Each process deforms and stresses a restored tooth structure in opposite direction. This study evaluated the…
Abstract Objective To determine if the results of resin–dentin microtensile bond strength (μTBS) is correlated with the outcome parameters of clinical studies on non-retentive Class V restorations. Methods Resin–dentin μTBS…
