Kinetics and mechanics of photo-polymerized triazole-containing thermosetting composites via the copper(I)-catalyzed azide-alkyne cycloaddition
Several features necessary for polymer composite materials in practical applications such as dental restorative materials were investigated in photo-curable CuAAC (copper(I)-catalyzed azide-alkyne cycloaddition) thermosetting resin-based composites with varying filler loadings and compared to a conventional BisGMA/TEGDMA based composite.

Growth and accelerated differentiation of mesenchymal stem cells on graphene-oxide-coated titanate with dexamethasone on surface of titanium implants
Titanium (Ti)-based materials have demonstrated their superiority among metallic materials in the biomedical field, such as orthopedics and dentistry, due to their excellent mechanical strength and favorable biocompatibility [1]. However, there are some disadvantages of current Ti-based implant materials that may hinder their further applications. For example, the biological inertness of Ti may induce the generation of fibrous tissue, which causes micro-movement between the bone and the interface, and ultimately, leads to the failure of implants.

Cell responses to cariogenic microorganisms and dental resin materials —Crosstalk at the dentin-pulp interface?
Resin monomers released from unpolymerized dental adhesives or composites and bacterial products like lipopolysaccharide (LPS) or lipoteichoic (LTA) are simultaneously present in specific applications following treatment of deep caries lesions. This review is focused on evidence concerning cell responses as a result of the interactions between adaptive mechanisms activated by resin monomers and signaling pathways of the immune response triggered by LPS or LTA originating from cariogenic microorganisms.

Re-mineralizing dentin using an experimental tricalcium silicate cement with biomimetic analogs
According to the concept of minimal invasive dentistry, caries-infected dentin should be removed, while caries-affected dentin is better preserved and re-mineralized to avoid potential pulp exposure in case of deep carious lesions [1,2]. In this respect, hydraulic calcium silicate cements (hCSCs), such as the commercially available Biodentine (Septodont, Saint Maur des Fosses, France) and ProRoot MTA (Dentsply Sirona, York, PA, USA), are not only indicated to treat various pulp-related endodontic complications [3,4], but could also serve as dentin re-mineralization agents [5 –9].

Characterisation of the interaction between crack extension, crack stabilisation and stress/strain relaxation in the polymeric matrix, the interplay between stress corrosion cracking and the mechanical response of a resin-based luting adhesive within a surface defect population could extend PLV restoration longevity by optimising cementation protocols.

Cytotoxicity and genotoxicity of a low-shrinkage monomer and monoacylphosphine oxide photoinitiator: Comparative analyses of individual toxicity and combination effects in mixtures
Residual monomers and other unbound substances from resin-based composites (RBCs) may reduce biocompatibility of RBCs via direct contact with oral tissues. Unbound components of composites diffuse through dentin into the pulp or elute into the oral cavity [1,2]. These substances may also be systemically distributed throughout the organism, either being taken up by circulating blood or swallowed by saliva, consequently causing adverse systemic effects [3,4].

Microstructural characterization of dental zinc phosphate cements using combined small angle neutron scattering and microfocus X-ray computed tomography
Zinc phosphate cements are a class of acid-base cements which find application in dentistry largely as luting or lining agents [1]. ZPC is one of the oldest dental cements, being introduced in the 1880s. Because of the inferior mechanical and biological properties, compared to some of the more recent bioactive restorative materials [2,3], the use of ZPC has significantly declined, although it possesses a successful track record, supported by clinical evidences [4,5]. However, a huge resident population of cemented restorations still exists, making the understanding of structure-limited properties important for the interpre...

Survival of directly placed ormocer-based restorative materials: A systematic review and meta-analysis of clinical trials
To replace part of the dental organ in a sustainable way and to meet increasing esthetic demand from patients, modern resin-based dental composites have undergone important improvements [1]. Even though sufficient mechanical properties have been obtained to consider them suitable for placement in load-bearing areas in posterior teeth, the stability and longevity of composite resin restorations should nevertheless be further optimized [2]. Controlling the degree of cure, polymerization shrinkage of the matrix and adhesion to adhesive systems is critical to improve biofunctional and biocompatibility properties [3,4].

Application of close-packed structures in dental resin composites
Dental resin composites are mainly comprised of an organic matrix mixed with silanized inorganic fillers, and can be cured to form a crosslinked composite polymer network with the blue light irradiation [1]. While the resin phase contributes to the toughness of the composites related to the mechanical strength in flexure or tension, their mechanical properties in regard to their modulus and hardness, are dominated by the filler particles for the similar resin matrices [2,3]. Recent research efforts have been aimed at optimizing filler formulations including filler loading, size, and morphology, with the aim of improving me...

Mainly because of their aesthetic properties, dental composites are gradually becoming the preferred restorative solution adopted by the dentists.

Strain development in bulk-filled cavities of different depths characterized using a non-destructive acoustic emission approach
Acoustic emission is commonly defined as transient elastic waves within a material, caused by the release of localized stress energy [1,2]. It is a non-destructive, highly sensitive technique, permitting the detection of dynamic processes in a material, such as the initiation and growth of extremely small flaws. In composite restorations, matrix cracking, filler de-bonding or adhesive failure may all contribute to acoustic emissions [3]. Only active features (e.g. crack growth) are recorded; thus, developing and stagnant defects can be distinguished in function of time. (Source: Dental Materials)

Flowable composites for restoration of non-carious cervical lesions: Three-year results
Non-carious cervical lesions (NCCLs) are defined as loss of dental hard tissue at the cemento-enamel junction [1]. The etiology of NCCLs is considered to be rather multifactorial with erosion, abrasion and abfraction (occlusal stress, tooth flexure) being main factors, conditioned by physical or chemical but not by microbiological processes [2,3]. Their prevalence has been reported to vary between 5 and 85% with a strong tendency to increase with age [1]. Therefore, considering the demographic change and an ageing population, the prevalence of NCCLs is likely to rise considerably in the future. (Source: Dental Materials)
