Abstract Objective Bioactive glasses (BAG) form, in contrast to formerly used implant materials, a stable bond with tissues, especially bone, when implanted. Nowadays BAGs are often mixed with a cement/composite…
Highlights • A new in vitro model for dentin permeability studies is presented. • The model simulates the positive pulpal pressure of natural teeth, it is suitable for long term…
Highlights • A novel method for inducing bioactivity of dental ceramic/bioglass composites by using laser energy has been proposed. • Application of specific laser irradiation parameters results in 3 times…
Abstract Objective We aimed to investigate the bioactivity and antibacterial effect of nitrogen plasma immersion ion implantation (PIII) on polyetheretherketone (PEEK). Methods According to the different modified parameters, the PEEK…
Abstract Objective To measure the mechanical properties of several CAD/CAM materials, including lithium disilicate (e.max CAD), lithium silicate/zirconia (Celtra Duo), 3 resin composites (Cerasmart, Lava Ultimate, Paradigm MZ100), and a…
Highlights • Shrinkage of bulk-fill and low-shrinkage composites was comparable to conventional composites. • Strain distribution across depth differed in 4-mm and 2-mm layered composites. • Marginal integrity was more…
Abstract Objectives The objective of this study was to investigate the effects of poly (amido amine) (PAMAM), composite with nanoparticles of amorphous calcium phosphate (NACP), and the combined PAMAM +…
Highlights • The hydrophilicity of nanogel may affect the performance of the adhesive. • Hydrophobic nanogel had less degradation and the best mechanical properties. • An amphiphilic nanogel showed the…
Abstract Objective Although cobalt–chromium (Co–Cr) dental alloys are routinely used in prosthodontics, the biocompatibility of Co–Cr alloys is controversial. The aims of the present study were to investigate the effects…
Abstract Objectives To analyze the influence of lightness, chroma and hue differences on visual shade matching performed by dental students. Methods 100 dental students (DS) volunteers with normal vision participated…
