Abstract Objective Investigate antimicrobial properties and surface texture of model composites with different concentration and alkyl chain length of quaternary ammonium monomers (QAS). Methods Monomers derived from QAS salts with…
Abstract Objectives Antibacterial monomers were developed to combat oral biofilm acids and caries; however, little is known on whether quaternary ammonium monomers (QAMs) would induce drug resistance in oral bacteria….
Highlights • Wrinkled mesoporous silica (WMS) particles exhibit better reinforcing effect in dental composites than regular silica. • Bimodal fillers containing WMS and smaller silica particles of appropriate sizes overcome…
Graphical abstract Highlights • Phenolic compounds from cashew nut shell liquid were investigated regarding the interaction with dentin collagen. • Aroeira bark extract was also, for the first time, investigation…
Highlights • AgNPs are applied in nanocomposites; implant coatings; anti-caries formulations; and in the treatment of oral cancer and local anesthesia. • In vitro results reveal the excellent antimicrobial activity…
Abstract Objective To investigate the effects of conditioning solutions containing ferric chloride (FeCl 3 ) on resin–dentin bond strength; on protection of dentin collagen against enzymatic degradation and on cathepsin-K…
Highlights • Anti-caries agents addition that are less likely to induce bacterial resistance. • Modulation of the virulence of Streptococcus mutans biofilm. • Alkali soluble and intracellular polysaccharides reduction of…
Abstract Objectives To evaluate the effect of mussel adhesive protein (MAP) on collagenase activity, dentin collagen degradation and microtensile dentin bond strength (μTBS). Methods Three groups were designed: 1. experimental…
Highlights • BioDent RPI yields more consistent dentin hardness values compared to Knoop tester. • BioDent affected less by dentin elastic recovery and surface conditions than Knoop. • Raman spectroscopic…
Clinical dentistry is a difficult topic because little is either black or white; instead there are many, many grey areas. Practitioners and dental students know that if you present a…
Highlights • The sintering shrinkage of Y-TZP might depend on the specimen shape. • Dimensional changes from sintering of Y-TZP do not occur uniformly in pre-molar shaped single copings. •…
Abstract Objective Composite resins do not adhere well to dental alloys. This weak bond can result in failure at the composite-metal interface in fixed dental prostheses and orthodontic brackets. The…
Highlights • High luminescence before aging was correlated to high amount of oxygen vacancies. • Aging is accompanied by a significant loss of yttrium from the surface. • Surface oxygen…
Abstract Objective To verify and calibrate a chemical model for simulating the degradation of the dentin-composite interface induced by multi-species oral biofilms in vitro. Methods Dentin-composite disks (5-mm dia. ×…
Highlights • Novel fluoride containing BAG-resin adhesive has a sustainable long term release of F, Ca and PO 4 . • The new adhesive reacts selectively in low pH environment…
Highlights • The effect of machining on fatigue strength of CAD/CAM ceramics was evaluated. • Machining reduces the flexural fatigue strength of CAD/CAM ceramics. • Y-TZP showed the greatest reduction…
Abstract Objective Nanoparticles having a size from 1 to 100 nm are present in nature and are successfully used in many products of daily life. Nanoparticles are also embedded per…
Graphical abstract Highlights • Addition of synthetized thio-urethane oligomers to methacrylate-based composites. • Composites filled with inorganic fillers varying refractive index and size. • Filler content affected the light-transmission and…
Graphical abstract Highlights • Binary and ternary Ti alloys were developed. • Ti–Zr alloys exhibited enhanced hardness and electrochemical stability. • Ti–Nb–Zr alloys presented an elastic modulus closer to that…
Highlights • Accurate gingival temperature rise was measured in swine gingiva. • Exposure to polywave LED light caused significant gingival temperature rise. • Higher exposure values increase the probability of…
