Abstract Objectives In this work the influence of the dimethacrylate monomer chemical structure on structural heterogeneity and physico-mechanical properties of the resulting polymer networks was investigated. Rigid aromatic dimethacrylate (Bis-GMA),…
Abstract Objectives To determine the diffusion coefficient, water sorption and solubility of various types of restorative dental composites and to evaluate the effect of acidic media (orange juice and coke)…
Thank you very much for reading and analyzing our paper very carefully. We enjoyed to read your comments. Your main concerns were addressed (1) to our practice-based statement that light-polymerizing…
Abstract Objectives The null hypothesis was that mechanical testing systems used to determine polymerization stress ( σ pol ) would rank a series of composites similarly. Methods Two series of…
Abstract Objectives This study evaluated catechin and chlorhexidine release from copolymers based on bis-GMA diluted with TEGDMA (R1), propoxylated bis-GMA–CH 3 bis-GMA (R2) or fluorinated bis-GMA–CF 3 bis-GMA (R3). Mechanical…
Abstract Objective The aim of this study was to evaluate if pH-neutralization behavior of self-adhesive resin cements has an influence on their mechanical properties. Methods pH-neutralization, water sorption, solubility and…
Abstract Objectives Esthetic demands and biocompatibility have prompted the development of all-ceramic dental crowns. Yttria tetragonal zirconia polycrystalline (Y-TZP) framework material has the best mechanical properties compared to other all-ceramic…
Abstract Objectives To assess the influence of veneer application on fracture behavior, namely failure load and failure mode, of standardized lithium-disilicate-based crowns. Methods Forty molar crowns (IPS e.max Press, IvoclarVivadent)…
Abstract Objectives Fluoride (F) releasing dental restoratives are promising to promote remineralization and combat caries. The objectives of this study were to develop nanocomposite containing calcium fluoride nanoparticles (nCaF 2…
Abstract Objectives To verify the hypothesis that crack analysis and a mechanical test would rank a series of composites in a similar order with respect to polymerization stress. Also, both…
Abstract Objective The aim of this study was to assess by using confocal microscopy (CLSM), AFM nano-indentation and microtensile bond strength test (μTBS) the quality of the resin–dentin interfaces created…
Abstract Objectives Test the hypotheses that there are equivalent wear rates for enamel-versus-enamel and ceramic-versus-enamel, analyzing the in vivo wear of crown ceramics, their natural enamel antagonists, and the corresponding…
Abstract Objective This study evaluated contact angle and shear bond strength of three commercial zirconia primers and compared them to a recently developed fluorination pre-treatment. Earlier investigations reported that plasma…
Abstract Objectives The aim of this study was to investigate the effect of variations in filler particle size and shape on the polymerization shrinkage-stress kinetics of resin-composites. Methods A model…
Abstract Objective The antimicrobial and physicochemical properties of experimental light curing composites prepared with fillers made of mechanically activated alkali-substituted calcium phosphates like CaKPO 4 , CaNaPO 4 or Ca…
