On the possibility of estimating the fracture toughness of enamel
Highlights • The energetic approach methodology is used to estimate the K C of bovine enamel. • Alternative energetic methodology has been developed to estimate K C of the enamel….
Proteoglycans affect monomer infiltration in the etch-and-rinse bonding technique
Abstract Objectives To identify proteoglycans (PGs) and collagen fibrils (CF) within human dentin by means of a dual immunofluorescent labeling technique and to investigate the monomer infiltration of two etch-and-rinse…
FEA and microstructure characterization of a one-piece Y-TZP abutment
Abstract Objectives The most important drawback of dental implant/abutment assemblies is the need for a fixing screw. This study aimed to develop an esthetic one-piece Y-TZP abutment to suppress the…
The effect of ultra-fast photopolymerisation of experimental composites on shrinkage stress, network formation and pulpal temperature rise
Highlights • TPO and CQ-based experimental resin composites were prepared and their physical properties analyzed. • The use of TPO with appropriate curing parameters leads to improved conversion. • Mechanical…
Mapping camphorquinone consumption, conversion and mechanical properties in methacrylates with systematically varied CQ/amine compositions
Abstract Objectives To evaluate conversion, bulk mechanical properties and camphorquinone (CQ) consumption in methacrylate resins, comprising a range of overall initiator concentrations and CQ/amine ratios. Methods BisGMA (Bisphenol-A glycidyl dimethacrylate),…
RAFT-mediated control of nanogel structure and reactivity: Chemical, physical and mechanical properties of monomer-dispersed nanogel compositions
Highlights • A RAFT-based initiating system successfully provided nanogels with latent reactivity. • The nanogel additives progressively reduced photopolymerization shrinkage and stress. • RAFT residual functionality on nanogels affected conversion…

Highlights • The energetic approach methodology is used to estimate the K C of bovine enamel. • Alternative energetic methodology has been developed to estimate K C of the enamel….
Controlled-release naringin nanoscaffold for osteoporotic bone healing
Highlights • We developed controlled-release naringin nanoscaffolds. • The nanoscaffolds were evaluated by an organ culture model. • The nanoscaffolds enhance functions of osteoblasts. • The nanoscaffolds suppress formation of…
The effect of fiber aspect ratio and volume loading on the flexural properties of flowable dental composite
Abstract Objective To evaluate the efficacy on flexural properties of flowable dental resin composite reinforced with short glass fiber of different aspect ratios (ARs) and volume percent loadings. It is…
Stability of bonds made to superficial vs. deep dentin, before and after thermocycling
Highlights • We compared the bonding stability between superficial dentin and deep dentin. • Bonds to deep dentin are more prone to degradation than superficial dentin. • MMPs distribution is…
Effects of quaternary ammonium-methacrylates on the mechanical properties of unfilled resins
Abstract Objective Adding antimicrobial/anti-MMP quaternary ammonium methacrylates (QAMs) to comonomer blends should not weaken the mechanical properties of dental resins. This work evaluated the degree conversion and mechanical properties of…
Effect of hesperidin incorporation into a self-etching primer on durability of dentin bond
Highlights • The use of natural cross-linkers incorporated primer is proposed. • The effect of hesperidin-incorporation primer on dentin bonding is demonstrated. • The immediate bond strength is increased by…
