“…However, our data suggest that higher C3S content may not directly translate into higher DTS as this property is also governed by the presence and reactions of other components like dicalcium silicate and aluminates, currently present as major or minor phases in commercial products (Primus et al 2019). Hence, further research shall unveil the effects arising from the interaction of these components on cement’s properties (Lin, Shie, et al 2021).…”

Calcium silicate (C3S) cements are available in kits that do not account for patients’ specific needs or clinicians’ preferences regarding setting time, radiopacity, mechanical, and handling properties. Moreover, slight variations in powder components and liquid content affect cement’s properties and bioactivity. Unfortunately, it is virtually impossible to optimize several cement properties simultaneously via the traditional “one variable at a time” strategy, as inputs often induce trade-offs in properties (e.g., a higher water-to-powder ratio [W/P] increases flowability but decreases mechanical properties). Herein, we used Taguchi’s methods and genetic algorithms (GAs) to simultaneously analyze the effect of multiple inputs (e.g., powder composition, radiopacifier concentration, and W/P) on setting time, pH, flowability, diametral tensile strength, and radiopacity, as well as prescribe recipes to produce cements with predicted properties. The properties of cements designed with GAs were experimentally tested, and the results matched the predictions. Finally, we show that the cements increased the genetic expression of odonto/osteogenic genes, alkaline phosphatase activity, and mineralization potential of dental pulp stem cells. Hence, GAs can produce cements with tailor-made properties and differentiation potential for personalized endodontic treatment.

“…Our previous results showed that inclusion of calcium silicate (CS) products into GelMa were able to enhance angiogenesis via increasing the secretion of VEGF from fibroblasts [20]. In fact, CS is the bioceramic that is always used as an endodontics material for root repair [21]. This was due to the sustained and gradual release of silicate (Si) and calcium (Ca) ions into the surrounding fluid upon degradation and immersion [22].…”

According to the Centers for Disease Control and Prevention, tooth caries is a common problem affecting 9 out of every 10 adults worldwide. Dentin regeneration has since become one of the pressing issues in dentistry with tissue engineering emerging as a potential solution for enhancing dentin regeneration. In this study, we fabricated cell blocks with human dental pulp stem cells (hDPSCs)-laden alginate/fish gelatin hydrogels (Alg/FGel) at the center of the cell block and human umbilical vascular endothelial cells (HUVEC)-laden Si ion-infused fish gelatin methacrylate (FGelMa) at the periphery of the cell block. 1H NMR and FTIR results showed the successful fabrication of Alg/FGel and FGelMa. In addition, Si ions in the FGelMa were noted to be bonded via covalent bonds and the increased number of covalent bonds led to an increase in mechanical properties and improved degradation of FGelMa. The Si-containing FGelMa was able to release Si ions, which subsequently significantly not only enhanced the expressions of angiogenic-related protein, but also secreted some cytokines to regulate odontogenesis. Further immunofluorescence results indicated that the cell blocks allowed interactions between the HUVEC and hDPSCs, and taken together, were able to enhance odontogenic-related markers’ expression, such as alkaline phosphatase (ALP), dentin matrix phosphoprotein-1 (DMP-1), and osteocalcin (OC). Subsequent Alizarin Red S stain confirmed the benefits of our cell block and demonstrated that such a novel combination and modification of biomaterials can serve as a platform for future clinical applications and use in dentin regeneration.

This study investigates the enhancement of dental composites using nano limestone and tricalcium phosphate fillers. Five composite formulations (TLC0-TLC4) were developed using organic polymers (Bis-GMA, TEGDMA, DMAEMA, CQ) and inorganic fillers. The methodology involved fabricating these composites and evaluating their physical and mechanical properties, including density, water absorption, solubility, polymerization shrinkage, hardness, compressive strength, and surface roughness. Results showed that density and voids increased with filler content, with TLC4 achieving the highest density at 1.39 ± 0.16 g/cm³. Water absorption and solubility increased, while polymerization shrinkage decreased to 0.66 ± 0.05% in TLC4. TLC4 demonstrated the highest hardness (72.8 ± 2.4 H.R.V.), compressive strength (248.41 ± 3.11 MPa), and surface roughness (0.62 ± 0.25 µm). Thermal analysis revealed significant weight loss and decomposition, while Fourier-transform infrared spectroscopy analysis provided detailed chemical composition insights. Wear resistance was evaluated through pin-on-disc tests and signal-to-noise ratio analysis, with FE-SEM confirming TLC4's superior performance. VIKOR analysis using the ENTROPY method ranked TLC4 as the most effective composite. This study offers valuable data for selecting and optimizing restorative dental materials.
