TL;DR: Survival rates of most types of all-ceramic SCs were similar to those reported for metal-ceramic SCs, both in anterior and posterior regions, and feldspathic/silica-based ceramics should be limited to applications in the anterior region.

TL;DR: The capacity of HCSCs to promote calcium-phosphate deposit suggests their use for dentin remineralization and tissue regeneration, and the most important investigations of the last 20 years are introduced.

TL;DR: Survival rates of all types of all-ceramic FDPs were lower than those reported for metal-ceramics, and the incidence of framework fractures and loss of retention was significantly higher for densely sintered zirconia F DPs compared to all other types of FDPS.

TL;DR: Fracture of tooth/restoration was the most common reason for failure, whereas failures related to aesthetic qualities were more frequent when restorations were placed for aesthetic reasons.

TL;DR: Current literature suggests that the restorative material might influence the development of secondary caries in different ways, and it should be emphasized that patient-related factors remain the most important determinant of secondaryCaries.

TL;DR: Enhanced curing time improved the investigated polymerization properties of bulk-fills and Z250 and TBF showed the lowest PVS and FSF the highest PSS in both curing modes.

TL;DR: Clinical data provide strong evidence that air-abrasion at a moderate pressure in combination with using phosphate monomer containing primers and/or luting resins provide long-term durable bonding to glass-infiltrated alumina and zirconia ceramic under the humid and stressful oral conditions.

TL;DR: Evaluated degree of conversion (DC), Knoop microhardness (KHN), internal marginal adaptation (IA), and polymerization shrinkage stress (PS) of one conventional and four bulk-fill composites found that higher PS correlated positively with higher proportion of interfacial gaps.

TL;DR: Recent advances on regenerative technologies to promote reconstruction of tooth and dental implant-associated bone defects are summarized to improve the biomimetic properties and regenerative potential of scaffold-based delivery platforms for next-generation patient-specific treatments with greater clinical outcome predictability.

TL;DR: A proportional inconsistency in findings hitherto encountered warrants a call for appropriate multivariable study designing to ensure that adequate data collection will enable osseointegration maximization and/or optimization, which will possibly lead to the engineering of endosteal implant designs that can be immediately placed/loaded regardless of patient dependent conditions.

TL;DR: An overview of fiber-reinforced composites (FRCs) that are a group of non-metallic dental biomaterials used in several fields of dentistry and the anisotropic nature of FRCs from the perspective of dental applications has increased in recent years.

TL;DR: Brand selection, thickness, and polishing of monolithic zirconia can affect the ultimate clinical outcome of the optical properties of zIRconia restorations.

TL;DR: Although the formation of microstructural defects is hard to be avoided during the SLM process, theSLM CoCrMo alloys can achieve improved mechanical properties than their casted counterparts, implying they are "defect-tolerant".

TL;DR: All tested specimens showed higher values than the prevailing minimum strength for plastic materials and their application in dentistry of 65MPa, underlines the applicability of PEEK in Dentistry and points out the possibility to offer patients metal free restorations, especially in the presence of allergies and/or bruxism.

TL;DR: Bevelling of the enamel was associated with a significantly reduced deterioration of the anatomical form compared to no bevelling but not with less marginal staining or less detectable margins, which, however, might be a random finding.

TL;DR: In general, rapid growth of lithium disilicates occurred only when maximum formation of lithium metasilicates had ended and groups with the extended temperature range and protracted holding time produced significantly higher elastic-modulus and hardness properties than the control group but showed similar flexural-strength and fracture-toughness properties with the control.

TL;DR: There are potential areas to be explored with antibacterial monomers for dentistry, and their use could have important implications for future more conservative dental treatments.

TL;DR: There is still a big need for clinical studies lasting longer than 5 years, as failure rates of composite restorations in posterior teeth increases with longer observation periods, which suggests a patient selection in regard to availability and dental awareness.

TL;DR: Surface treatment improved the aging resistance of Y-TZP zirconia and showed a similar trend in LTD behavior, while the five yttria-stabilized TZP (Y-TzP: Aadva, In-CeramYZ, IPS e.max ZirCAD, LAVA Frame,LAVA Plus) zIRconia showed the highest monoclinic volume fraction.

TL;DR: The improvement of the mechanical properties of modifiedTi G4 means that Ti G5 can be safely replaced by Ti G4 Hard without compromising the fracture resistance, with the advantage of not releasing toxic ions.

TL;DR: Although antimicrobial activity of restorative materials is important, the introduction of antimicrobial agents/techniques should not be at the expense of other material properties, as environmental changes within a material may affect the bacterial response to the antimicrobial.

TL;DR: In this paper, the synthesis, materials characterization, antimicrobial capacity, and cytocompatibility of novel ZnO-loaded membranes for guided tissue/bone regeneration (GTR/GBR) were reported.

TL;DR: After 13 years, the clinical effectiveness of Clearfil SE Bond in non-carious Class-V lesions remained excellent, with selective acid-etching of the enamel cavity margins only having some minor positive effect on marginal integrity and absence of marginal discoloration.

TL;DR: The results suggest to use a thickness of 0.7-1mm for non-retentive full-coverage adhesively retained occlusal lithium disilicate ceramic restorations in groups with smaller ceramic thickness, luting to dentin or composite provided statistically significant higher fracture resistance thanLuting to enamel only.

TL;DR: Smaller grains caused less transformation, and aging caused increased roughness, but grain size did not influence the amount of increased surface roughness.

TL;DR: The aim of the study was to determine the time-dependence of degree of conversion (DC) at that depth during 24h post-irradiation of bulk-fill resin composites.

TL;DR: The three conventional resin composites showed good clinical performance during the 30 year evaluation and the chemical cured resin Composites showed better performance than the light-cured composite.

TL;DR: The relatively low fracture toughness and high residual tensile stress in porcelain veneer of zirconia restorations may contribute to the higher chipping rate and larger chip size in zir Conceramic FDPs relative to their metal-ceramic counterparts.

TL;DR: The application of a hydrophobic resin coating improved the 24h and the 6m performances of all three adhesives systems in SE mode and resulted in a significant reduction in NL when HC was applied.

TL;DR: A favorable tissue response is anticipated to occur with the use of Biodentine as a blood clot-protecting material for pulpal revascularization and the potential adverse biological effects of TheraCal LC on hDPSCs are validated.
