Highlights • There was significant difference in the response of human and other mammalian cell lines to dental composites making extrapolation of the results not accurate always. • The type…
Abstract Objectives To evaluate thin-film bond strength between a bonding agent and human dentin, using a scratch test, and the characteristics and accuracy of measurement. Methods One-step bonding agents (BeautiBond;…
Abstract Objectives Despite their various advantages, such as good esthetic properties, absence of mercury and adhesive bonding to teeth, modern dental composites still have some drawbacks, e.g., a relatively high…
Abstract Objectives This study evaluated the effect of etching using 2% proanthocynidin-containing 10% phosphoric acid 2% PA/10% PhA vs. 35% phosphoric acid 35% PhA on immediate (IM) and 6-months (6…
Highlights • No adequate CIELAB-based indices are available for whiteness evaluation in dentistry. • Visual data optimization methods allowed the development of a new whiteness index-WI D . • WI…
Graphical abstract Highlights • Mono or polycrystalline alumina particles were added to a dental porcelain. • Particle coating was carried out by heat treatment of a silica precursor. • The…
Highlights • Capacity of crown restorations to sustain high bite force has been measured on manufactured, anatomically-correct specimens for three classes of monolithic materials. • Extended finite element modeling has…
Highlights • Mechanical performance of air-abraded or acid-etched ceramic was investigated. • Abrasion and acid-etching reduced ceramic mechanical strength and reliability. • Abraded ceramic had the poorest mechanical performance among…
Abstract Objectives Bioactive glass forms a bone mineral apatite interface and can be engineered to promote optimal bone regeneration. Strontium (Sr 2+ ) stimulates osteoblast and inhibits osteoclast activities in…
Abstract Objectives This study evaluated the endogenous matrix metalloproteinase (MMP) activity of demineralized dentin matrix following 1 or 5 min pretreatment by various collagen crosslinkers. Generic MMP activity assay, total…
Highlights • Grinding increases the ceramic’s resistance towards ageing at the subsurface. • The activation energies compares well with previous reported values. • After aging at 37 °C, predicted and…
Graphical abstract Highlights • MDP containing universal adhesive alone provides effective chemical bonding to Y-TZP. • Silica coating + silanization provided higher hydrolytic stability than applying MDP. Abstract Objectives To…
Highlights • Demineralization of dentin causes a decrease in the surface free energy. • Acetone added to a nano-HA solution increases the surface wetting of dentin. • Acetone facilitates the…
Highlights • XFEM results were in good agreement with those of the experimental results. • XFEM enabled us to capture a more accurate load at first sign of a crown’s…
Graphical abstract Highlights • Application of photo-catalytic activities of TiO 2 NPs could be tuned through dental resins. • Adding TiO 2 NPs in hydroxyl-rich resins may produce materials with…
Abstract Objectives Recently several zirconia primers have been introduced to mediate bonding of dimethacrylate resins to yttria-stabilized zirconia frameworks (Y-TZP). The aim of the study was to evaluate the changes…
Abstract Objectives The literature reports inconsistent results regarding using configuration factor (C-factor) as an indicator to reflect the generation of polymerization shrinkage stress (PS) from dental restorative composites due to…
Abstract Objective Acids, such as those used in adhesive dentistry, have been shown to solubilize bioactive molecules from dentin. These dentin matrix components (DMC) may promote cell proliferation and differentiation,…
Highlights • Fluoride from dental materials works on caries similarly as fluoride from dentifrices. • The effect of fluoride from dental materials is based on in vitro and in situ…
