Abstract Objectives To evaluate the probability of survival and failure modes of implant-supported resin nanoceramic relative to metal-ceramic crowns. Methods Resin nanoceramic molar crowns (LU) (Lava Ultimate, 3M ESPE, USA)…
Highlights • UV-irradiation for the hydrophilization of dental implants was investigated. • Original, out-of-the-box titanium, zirconia, and PEEK implants were hydrophobic. • UV-A switched solely implants with anatase coating into…
Abstract Objective Chipping and/or delamination represent a clinical failure of porcelain fused to zirconia (PFZ) prostheses. Causes and solutions have not been completely clarified. The present study was aimed at…
Highlights • New fractional derivative type of viscoelastic model is developed for four different uncured composite resins. • Experiments using rheometer with parallel plates are performed and the model parameters…
Abstract Objectives The Schwickerath three point bending adhesion test is the basis of the International Standard ISO 9693:1999 procedure for assessing porcelain bonding to metals . It has also been…
Highlights • Residual stress in the veneers was quantified by means of Vickers indentation. • Effect of σ R on Hertzian cone crack propagation was determined. • The CTE mismatch…
Highlights • 88 prospective, clinical trials (1996–2015) were analyzed in terms of survival of posterior composite restorations. • Significant findings were only observed for short-term studies and by including all…
Graphical abstract Highlights • Dentin contains proteases which are uncovered and activated during the adhesive procedures. • We evaluated the inhibitory effect of crosslinkers on MMP- and cathepsin K-mediated degradation….
Highlights • We studied the effect of various thermal processing on the crystallization kinetics, crystallite microstructure, and strength of a lithium disilicate system. • The growth of Li 2 O–2SiO…
Abstract Objectives The photoinitiator diphenyl-(2,4,6-trimethylbenzoyl)phosphine oxide (TPO) is more reactive than a camphorquinone/amine (CQ) system, and TPO-based adhesives obtained a higher degree of conversion (DC) with fewer leached monomers. The…
Highlights • Full-coverage occlusal veneers of different thicknesses were tested. • The lithium disilicate occlusal veneers were exposed to masticatory simulation. • Only specimens with the thickest dimension fully survived…
Abstract Objective This study tested whether treatment of demineralized dentin with polyacrylic acid (PAA) has any activatory or inhibitory activity on dentin matrix metalloproteinases (MMP)s or cathepsin K (CAT-K). Methods…
Highlights • We used a staircase method for evaluating cyclic loads-to-failure of crowns. • We compared the results from cyclic and monotonic testing. • 50 μm was more favorable for…
Highlights • Human lymphocytes were exposed to HEMA and TEGDMA for 24 h. • Cytotoxic effects were measured only in TEGDMA (100 μM) treated cells. • Genotoxic effects were detected…
Abstract Objectives To investigate the single-edge notched (SEN) bend fracture toughness ( K IC ) testing methodology as a reproducible and discriminatory mechanical testing protocol for encapsulated and hand-mixed glass-ionomers…
Highlights • Orthodontic bonding indices an increase in BPA concentration immediately after the 1st post-bonding rinse. • Reduced BPA concentration after the 2nd post-bonding rinse. • BPA concentrations measured after…
Abstract Objective This work presents the results obtained from the study of sorption/desorption process of some food/oral simulating liquids (FSLs) by the new marketed dental light-cured nanohybrid composite Kalore GC….
Highlights • Sealing performance was measured in five adhesives by optical coherence tomography. • Sealing and bond strength performance within individual specimens were correlated. • Interfacial defects increased after thermal…
Abstract Objectives The aim of this randomized controlled study was to evaluate the long term effectiveness of a reduced shrinkage stress resin composite in Class II restorations. The material was…
Abstract Objectives Mismatch in thermal expansion coefficient between core and veneering ceramic (Δ α = α core − α veneer , ppm/°C) is reported as a crucial parameter influencing veneer…
