Summary: This study evaluated the effects of three different concentrations of nano-graphene oxide (GO) powder on the setting time, compressive strength, pH, calcium ion release, and antibacterial activity of mineral trioxide aggregate (MTA). The results showed that the addition of 1% GO significantly improved the performance of MTA without compromising its compressive strength.

Summary: This study compared the effects of TheraCal LC and biodentine on direct pulp capping using a rabbit model. The results showed that biodentine had a thicker and more continuous dentine bridge compared to TheraCal LC. Both materials had a similar inflammatory effect on the pulp.

Summary: A novel dental repair material based on tricalcium silicate (C3S) was developed by adding ceria-stabilized zirconia (Ce-TZP) and dipotassium hydrogen phosphate (K2HPO4) as the setting accelerator. The composite cement exhibited excellent physical and chemical properties, antimicrobial activity, in vitro cytocompatibility, outstanding fracture toughness, and fast-setting ability.

Summary: This study aimed to evaluate the effects of Biodentine on the osteogenic differentiation of HPLFs in vitro and the healing of furcal perforations created experimentally in rat molars in vivo, in comparison to MTA. The results demonstrate that the nanoparticle size distribution of Biodentine is critical for osteogenic potential at an earlier stage compared to MTA.

Summary: This paper investigates the modification mechanism of cellulose nanocrystals (CNCs) in cement by simplifying the complex cement system to pure tricalcium silicate (C3S) mineral components. The researchers explored the hydration characteristics of C3S mixed with different amounts of CNCs and the chemical environment of the hydration products. It was found that CNCs have a similar effect to superplasticizers in reducing the hydration exothermic, promoting the growth of Ca(OH)2 crystals, and providing additional nucleation sites for the generated C-S-H. The elucidation of the modification mechanism of CNCs provides theoretical guidance for its application in cement.

Summary: When graphene oxide (GO) is mixed with cement, it can exist in different dispersion states, including well-dispersed, grain-adsorbed, and self-agglomerated. The effects of GO in grain-adsorbed and self-agglomerated states on tricalcium silicate (C3S) hydration were investigated in this study. The results showed that GO in grain-adsorbed state limits the accessibility of reactant for hydration at early age, while GO in self-agglomerated state absorbs calcium ions from the pore solution, leading to inhibition of hydration. These findings enhance the understanding of GO in cement hydration and its potential use in cementitious materials.

Summary: Tooth cavity is a common problem due to demineralization, which can be controlled with factors like fluoride. However, excessive fluoride intake can lead to fluorosis. Therefore, an alternative non-fluoride agent is needed for dental caries prevention.

Summary: The cohesion of cement arises from the organization of interlocked ions and water, progressively confined in nanoslits between charged surfaces of calcium-silicate-hydrates. By reducing dielectric screening and strengthening ionic correlations, the cohesive strength of cement is enhanced.

Summary: The study investigated the in vivo dissolution of tricalcium silicate bone cement and found that the dissolution model was a mass loss rather than a volume decrease. The initial dissolution was attributed to the release of Ca(OH)2, while the later dissolution was due to the decalcification of C-S-H gel. Despite a decrease in mass after 6 weeks, the pores created were not large enough for bone tissue migration into the cement.

Summary: This study aimed to develop a novel TCS-based cement with excellent anti-washout ability by incorporating KGM/CF complex. The results showed that KGM enhanced the washout resistance of TCS pastes but hindered hydration reaction, while CF further increased the anti-washout ability and shortened the setting time of TCS cement. The compressive strength of TCS cement with CF increased, and the addition of CF had no obvious effect on flowability.

Summary: This review examines the application of sol-gel synthesized bioactive glasses (BAGs) in restorative dentistry. The study finds that sol-gel derived BAGs are mainly used in the treatment of hypersensitive dentine and for pulp-dentine tissue engineering, showing potential for improving biological properties, antibacterial effects, hardness, acid buffering, and remineralization. However, the addition of BAGs may have detrimental effects on optical properties, highlighting the need for further research and improvement.

Summary: This study synthesized tricalcium silicate (TCS) and mesoporous bioactive glass nanoparticles (MBGNs) doped with lithium (Li) by the sol-gel method. The results showed that TCS particles formed irregular nano-structured agglomerates, while MBGNs were mesoporous spheres. There was a very low incorporation of Li ions into MBGNs. Both TCS and MBGNs had an alkalizing effect on the immersion media and exhibited bioactive properties, but MBGNs showed better antimicrobial properties.
