Special Issue Information

Dear Colleagues,

This Special Issue of Materials, titled "Development and Research of New Dental Materials", focuses on the dynamic and evolving field of dental material science. It will highlight the latest advancements in the development, characterization, and application of innovative dental materials designed to meet the ever-growing demands of modern dentistry. Topics of interest include, but are not limited to, new composites, ceramics, polymers, adhesives, bioactive materials, and metal alloys with enhanced mechanical properties, biocompatibility, and longevity.

We welcome research that explores novel fabrication techniques, surface treatments, and functionalization methods to improve material performance in the challenging oral environment. Studies investigating the interaction between dental materials and biological tissues, as well as their clinical performance in restorative, prosthetic, and regenerative dentistry, are particularly encouraged, alongside work on preventive dentistry materials, such as remineralizing agents and coatings.

By gathering cutting-edge research and critical reviews, this Special Issue aims to provide insights that will shape the future of dental materials and improve patient outcomes. Researchers and clinicians are invited to submit original studies, comprehensive reviews, and case reports to contribute to this vital and rapidly advancing field.

The purpose of this study was to evaluate the effect of different framework materials and thermal aging on the shear bond strength (SBS) of gingiva-colored composites used in fixed dental restorations. A total of 270 samples (10 × 10 × 2 mm3) were prepared using titanium, zirconia, and modified polyetheretherketone (modified PEEK). Three gingiva-colored composites (Gradia Gum, Anaxgum, Nexco) were applied after surface polishing and sandblasting. All specimens were stored in water at 37 °C for 24 h, then half of each group was subjected to thermal aging consisting of 10,000 cycles at temperatures between 5 and 55 °C. SBS testing was performed using a universal testing machine with a crosshead speed of 1 mm/min. Bonding failures were analyzed under a stereomicroscope, and one sample from each group was examined using a scanning electron microscope. SBS data were analyzed using three-way ANOVA with composite type, framework material, and thermal aging as factors, followed by pairwise comparisons (SPSS 23.0; p < 0.05). The highest SBS was recorded for the zirconia framework combined with Gradia Gum, specifically in the group without thermal aging (p < 0.05), while the lowest was observed for zirconia combined with Nexco after thermal aging (p < 0.05). Adhesive failures were predominant in the modified PEEK groups, whereas mixed failures occurred more frequently in titanium and zirconia groups. Both composite type and framework material significantly influenced SBS values, with thermal aging having a detrimental effect across all groups. This study demonstrates that both framework material and composite type affect bond strength, with specimens not subjected to thermal aging maintaining better adhesion. Thermal cycling reduced SBS in all groups, although the extent varied by material combination. Full article

This study aims to compare the osteogenic potential of premixed hydraulic calcium silicate-based sealers (HCSSs) with an epoxy resin-based sealer in human bone marrow-derived stem cells (hBMSCs). Three HCSSs (White Endoseal MTA, One-Fil, EndoSequence BC Sealer) were compared with AH Plus Jet, an epoxy resin-based sealer. Disk-shaped specimens were prepared using sterilized Teflon tubes and immersed in osteogenic medium to create eluates. hBMSCs were cultured in each eluate, and osteogenic potential was assessed by alkaline phosphatase (ALP) activity (n = 6), Alizarin Red-S (ARS) staining (n = 6), quantitative real-time polymerase chain reaction (qPCR) (n = 3), and Western blot analysis. Statistical analyses were conducted using SPSS (version 24.0), with significance set at p < 0.05. All experimental groups exhibited higher ALP activity than the control on day 4. ARS staining of HCSSs differed significantly from AH Plus Jet on day 14 (p < 0.05), while White Endoseal MTA exhibited the highest intensity. qPCR revealed that EndoSequence BC Sealer induced the highest SMAD1 expression on day 4, while One-Fil and EndoSequence BC Sealer significantly upregulated RUNX2 expression compared with AH Plus Jet (p < 0.05). Western blotting confirmed that EndoSequence BC Sealer induced the highest RUNX2 protein expression. Collectively, premixed HCSSs promoted superior mineralization and RUNX2 expression compared to conventional resin-based sealer in hBMSCs. Full article

The present research compared the design, metallurgical properties, and mechanical characteristics of the ProTaper Ultimate instruments with five multifile systems. A total of 469 new nickel–titanium rotary finishing instruments, all 25 mm in length but varying in size, taper, and metal alloy composition, from six different multifile systems (ProTaper Ultimate, ProTaper Next, ProFile, Mtwo, EndoSequence, and GT Series X), were inspected for irregularities and analyzed for their spiral density (spirals per millimetre), blade design, surface finishing, alloy composition, phase transformation temperatures, and mechanical performance (microhardness, torsional, and bending resistance tests). Group comparisons were performed using Kruskal–Wallis and one-way ANOVA with post hoc Tukey’s tests (α = 5%). ProFile instruments exhibited a greater number of spirals and a higher density of spirals per millimetre compared to the other systems. Microscopic analysis revealed distinct tip geometries and blade designs among tested instruments. All of them displayed parallel marks from the machining process, but the EndoSequence system had the smoothest surface finish. The alloys of all instruments consisted of an almost equiatomic ratio of nickel to titanium. At the testing temperature, the ProTaper Ultimate system exhibited a complete R-phase crystallographic arrangement, while the ProFile and Mtwo systems were fully austenitic. The ProTaper Ultimate F2, F3, and FX instruments demonstrated the highest maximum torque values (1.40, 1.45, and 3.55 N.cm, respectively) and the lowest maximum bending loads (202.7, 254.9, and 408.4 gf, respectively). EndoSequence instruments showed the highest angles of rotation, while the highest microhardness values were recorded for GT Series X (407.1 HVN) and ProTaper Next (425.0 HVN) instruments. The ProTaper Ultimate system showed a high spiral density per millimetre and a complete R-phase crystallographic arrangement at room temperature, which significantly contributed to its superior flexibility and torsional strength when compared to the other tested systems.
