Abstract Objective To evaluate degree of conversion (DC), Knoop microhardness (KHN), internal marginal adaptation (IA), and polymerization shrinkage stress (PS) of one conventional and four bulk-fill composites. Methods Bulk-fill composites…
Highlights • Effect of extensive adjustment on both ISO specimens and realistic crowns was assessed. • Profilometric & Weibull analysis, REM, and finite element analysis were used. • The results…
Highlights • The viscoelastic properties of bulk fill composites are tested. • The materials are tested dry and wet under different temperatures. • Degree of conversion is calculated at the…
Abstract Objectives Evaluate the effect of environment on post-gel shrinkage (Shr), cuspal strains (CS), microtensile bond strength (μTBS), elastic modulus ( E ) and shrinkage stress in molars with large…
Abstract Objectives In pulpal revascularization, a protective material is placed coronal to the blood clot to prevent recontamination and to facilitate osteogenic differentiation of mesenchymal stem cells to produce new…
Abstract Objective The functional monomer 10-MDP has been considered as one of the best performing functional monomers for dental adhesives. Different adhesives containing 10-MDP are commercially available, among which many…
Highlights • Comparator choice in restorative trials is assessed via network analysis. • Comparisons against certain established standards are common. • Many trials compare within, not between material classes. •…
Highlights • A significant correlation exists between grain size and monoclinic transformation. • Aging created a slight increase in surface roughness. • No significant correlation between grain size and surface…
Abstract Objectives To evaluate the chemical, mechanical, and biological properties of modern composite surface sealers (CSS) having different compositions. Methods The CSS products tested were Biscover LV (BC), Durafinish (DF),…
Highlights • We compared adherence of oral Streptococci to titanium nanotubules. • We showed that adherence increased with nanotubule diameter. • Adherence was also correlated with surface fluoride content. •…
Abstract Objective The purpose of this study was to investigate a range of variables affecting the synthesis of a miserite glass-ceramic (GC). Methods Miserite glass was synthesized by the melt…
Highlights • This study evaluates the flexural strength, Weibull modulus, and fracture mode of ceramic structures obtained by the CAD-on technique. • This study tested the hypothesis that trilayer and…
Highlights • Ion interaction between monolithic zirconia material and an acidic aqueous environment may occur, with initial signs of the materials’ corrosion resistance. • An acidic aqueous solution has a…
Highlights • Heterogeneous macro-micro and nanostructures were formed in the CoCrMo alloys prepared by SLM. • The interlocking of “weld lines” and elongated grains generated 3D textures resembling weaved fabrics….
Highlights • The FRP/sleeve combination effectively reinforced plupless premolars with flared root canals under firm bonding condition. • The maximal principle stress in restored premolars increased dramatically, once interfacial de-bonding…
Highlights • A novel resin cement was developed. • The phosphate groups of 2MP formed hydrogen bonds with the collagen. • The hydrogen bonds prominently decreased in number in the…
Highlights • Micro-CT and SS-OCT may be useful non-destructive methods for evaluating internal adaptation. • The microleakge measured by micro-CT was lower than that of SS-OCT, however the two measurements…
Graphical abstract Highlights • The maximum polymerization rate of double bond can be adjusted by TTMSS concentration. • The polymethacrylate network structure became more homogenous with the decreasing of polymerization…
Abstract Objectives To compare visual and instrumental shade matching performances using two shade guides and three color difference formulas. Methods One hundred dental students (DS) volunteers (35 males and 65…
Highlights • We revealed differences on the microbial diversity of titanium or zirconia abutments. • Our results revealed differences in the microbial counts from titanium and zirconia. • Data suggests…
