Abstract Objectives The absorbance profile of photoinitiators prior to, during and following polymerization of light curable resin-based materials will have a significant effect on the cure and color properties of…
Abstract Objective To evaluate the reinforcement efficacy of hydroxyapatite (HA) whiskers in bis-GMA-based dental restorative composites and determine the effect of volume fraction on the mechanical properties. Methods Silanized HA…
Abstract Objectives The purposes of this study were to evaluate color shifting at the boader of resin composite restorations after placement in human tooth cavities in vitro. Methods Twenty extracted…
Abstract Objective In the paper laser scanning was used to evaluate, by indirect methods, the accuracy of computer-designed surgical guides in the oral implant supported rehabilitation of partially or completely…
Abstract Objectives The toxicity of monomers like bisphenol-A-glycidyldimethacrylate (BisGMA) and urethane-dimethacrylate (UDMA) to cells is well studied. In these studies solubilizers, which have a toxic potential, are used to dissolve…
Abstract Objectives For root canal fillings, a thin layer of sealer cement is generally recommended. However, with resin-based sealers, lower bond strength to dentin has been shown in thin layers…
Abstract Objective To evaluate the reliability and accuracy of computer-designed surgical guides in osseointegrated oral implant rehabilitation. Materials and methods Six implant rehabilitations, with a total of 17 implants, were…
Abstract Objectives To characterize the effect of crevice corrosion on the strength of dental silver amalgam as determined by the Hertzian ‘ball on disc’ method, with a view to providing…
Abstract Objective The objective of this study was to compare several dental restoratives currently advertised as low-shrinkage composites (Clearfil Majesty Posterior, Kalore, Reflexions XLS Dentin and Venus Diamond) with a…
Abstract Objectives The aim of the study was to evaluate the contraction stress, microhardness and polymerization kinetics of three self-adhesive cements vs. conventional dual-cure resin cement. Methods Cements tested were:…
Abstract Objectives The application of an electric field has been shown to positively influence the impregnation of the resin monomers currently used in dentin bonding systems during hybrid layer formation….
Abstract Objective Fillers are widely utilized to enhance the mechanical properties of polymer resins. However, polymerization stress has the potential to increase due to the higher elastic modulus achieved upon…
Abstract Objectives The management of demineralized dentin resulting from dental caries or acid erosion remains an oral healthcare clinical challenge. This paper investigates, through a range of studies, the ability…
Abstract Objectives The aim of this study was to numerically evaluate the effects of filler contents and resin properties on the material properties of dental composites utilizing realistic 3D micromechanical…
Abstract Objectives Verify the influence of different filler distributions on the subcritical crack growth (SCG) susceptibility, Weibull parameters ( m and σ 0 ) and longevity estimated by the strength–probability–time…
Abstract Objectives The aim of the present study was to investigate an antimicrobial additive containing experimental resin composite with regards to its impact on biofilm formation under oral conditions. Methods…
Abstract Objective We examined the correlation between clinical wear rates of restorative materials and enamel (TRAC Research Foundation, Provo, USA) and the results of six laboratory test methods (ACTA, Alabama…
Abstract Objective To investigate the effect of laser surface treatment of cast titanium alloy on microstructure and mechanical properties. Methods Dumbbell- and plate-shaped cast titanium specimens were prepared for mechanical…
Abstract Objectives The aim of this study was to test the new resin composite “NECO” as a material for indirect restorations clinically. Methods Forty-five patients were selected, of which 12…
Abstract Objectives Bonding of all-ceramic restorations has become routine practice mainly due to results from clinical studies. Sandblasting has been advocated for surface treatment of many ceramics, based on results…
