Abstract Objective To investigate the influence of implant design factors in terms of bone integrity and implant stability. Materials and methods A 3D parametric CAD model was developed. Then, once…
Abstract Objectives The purpose of this study was to compare four medium particles currently used for in vitro composite wear testing (glass and PMMA beads and millet and poppy seeds)….
Abstract Objectives The purpose of this study was to prepare antibacterial and radiopaque dental resin through adding one polymerizable quaternary ammonium compound with iodine as counter anion into Bis-GMA/TEGDMA (50/50,…
Abstract Objectives The aim of this study was the characterization of siloran-derived composite eluates in conjunction with their putative impact on human gingival keratinocytes (HGK), i.e. levels of total RNA…
Abstract Objectives This study aimed to evaluate the adhesive properties of a MDP-containing resin cement to a colored zirconia ceramic, using an experimental zirconia–silica coating technique with different priming conditions….
Abstract Objective To determine the influence of cement thickness and ceramic/cement bonding on stresses and failure of CAD/CAM crowns, using both multi-physics finite element analysis and monotonic testing. Methods Axially…
Abstract Objectives To determine the creep deformation of several “bulk-fill” resin-composite formulations in comparison with some other types. Methods Six resin-composites; four bulk-fill and two conventional were investigated. Stainless steel…
Abstract Objective The aim of this in vitro study was to evaluate the influence of different finishing procedures on the wear behavior of zirconia against natural enamel. Methods 64 quadratic…
Abstract Objectives Compressive stress has been intentionally introduced into the overlay porcelain of zirconia–ceramic prostheses to prevent veneer fracture. However, recent theoretical analysis has predicted that the residual stresses in…
Abstract Objectives To reduce polymerization-induced shrinkage stress while maintaining mechanical properties, reversible addition-fragmentation chain transfer (RAFT)-capable functional groups were incorporated into a photopolymerizable dimethacrylate-based dental composite. We hypothesize that the…
Abstract Objective To study the inhibitory effect of various commercially available concentrations of silver diamine fluoride (SDF) solutions on matrix metalloproteinases (MMPs). Methods Three SDF solutions with concentrations at 38%,…
Abstract Objective The purpose of our study was to evaluate the effects of surface treatment on the microtensile bond strength (MTBS) of repaired silorane-based composites (Filtek Silorane (Silorane), 3M ESPE)….
Abstract Objective Antibacterial bonding agents are promising to hinder the residual and invading bacteria at the tooth–restoration interfaces. The objectives of this study were to develop an antibacterial bonding agent…
Abstract Objectives To develop a novel methodology to generate specimens for bi-axial flexure strength (BFS) determination from a ‘chair-side’ CAD–CAM feldspathic ceramic with surface defect integrals analogous to the clinical…
Abstract Objectives To evaluate and compare three novel coupling agents: 2-hydroxyethyl methacrylate, itaconic acid and oleic acid to two silane coupling agents, one commercial silane product and 3-acryloxypropyltrimethoxysilane on the…
Abstract Objectives Half of dental restorations fail in 10 years, with secondary caries as the main reason. Calcium phosphate composites could remineralize tooth lesions. The objectives of this study were…
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 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…
