Summary: This study compared the reliability of torque applied to osteosynthesis screws by oral and maxillofacial surgeons and residents. It found that surgeons had higher compliance with the reference torque intervals. The residents had inadequate accuracy and reliability with the 1.5 mm screws, but showed improvement over time.

Summary: This study investigated the microbiologically influenced corrosion (MIC) of 316L stainless steel (SS) caused by oral microbiota using HOMINGS 16S rRNA gene sequencing technology, electrochemical, and surface analysis techniques. The results showed that oral microbiota formed multi-species biofilms with varying structures and composition of bacterial strains on the 316L SS coupons. The presence of oral microbiota led to more severe pitting corrosion and faster dissolution of metallic ions. The findings suggest that electroactive microorganisms in oral microbiota may play a significant role in accelerating corrosion.

Summary: This study found that implants with wider body diameters released more metallic elements, with Ti-6Al-4V implants releasing significantly more compared to Ti-CP4 and Ti-15Zr. Ti-CP4 and Ti-15Zr appear to be more suitable materials, but further research is needed to elucidate the biological effects of these fine particles and/or metallic species.

Summary: The study demonstrates that carbon films can significantly reduce friction between stainless steel archwires and brackets, with archwires coated in graphene embedded carbon films showing the lowest friction coefficient. Prolonged immersion in artificial saliva, however, can deteriorate the friction behavior of the coated archwires.

Summary: This study investigated the effect of surface treatment on peri-implant jawbone by applying lateral load to anchor screws that underwent surface treatment. The structure, cellular dynamics, and quality of the bone surrounding anchor screws were analyzed, and bone microstructural characteristics were evaluated. The results showed that bone-implant contact rate increased rapidly in the surface-treated group, and the measured values of bone lacuna morphometry and collagen fiber bundle diameter varied at different regions surrounding the anchor screw. The findings suggest that anchor screw surface activation may facilitate early bone contact and enable early loading in clinical practice.

Summary: Titanium dioxide-silica composite nanoparticles were synthesized using a verified Stober sol-gel method. The resulting nanoparticles consisted of titanium dioxide cores surrounded by ultrafine silica particles, forming a thin shell. These nanoparticles were deposited on a stainless steel substrate via electrophoretic deposition to enhance its biological response. The presence of a silica shell increased the surface roughness, eliminated cracks, and improved the adhesion and barrier performance of the coating.

Summary: This study uses a multiphysics model based on the finite element method to investigate the rarely studied crevice corrosion behavior of stainless steel and titanium overlapping. The model considers damage due to corrosion, species transportation, electrochemical reactions, homogeneous reactions, and the influence of corrosion products. Simulation results reveal that the maximum corrosion occurs at the crevice opening, confirming the IR drop theory. The pH and Cl- concentration reach their minimum and maximum values in the middle and opening of the crevice, and the influence of crevice size on corrosion is also examined.

Summary: The dental practice-based research networks (D-PBRN) play an important role in structuring clinical research in private practices and increasing research scope. The majority of scientific production is from the USA, and D-PBRN helps in studying a higher number of diverse centers, bridging the gap between private practice and research.

Summary: The study evaluated the mechanical, biological, and polymerization behavior of a flowable bulk-fill composite with fibers as a dispersed phase in vitro. EXF showed superior fracture toughness, shrinkage stress, and less cytotoxic effect compared to FBF and SDR. All three composites exhibited slight cytotoxic effects on day one but an increase in metabolic activity was observed in cells treated with EXF extracts on day 5.

Summary: This systematic review aims to summarize the effects of therapeutic radiation on tooth properties and emphasizes the need for expertise in materials science in dental hard-tissue characterization. The findings suggest a significant impact of radiation on the organic matrix of dentin, while the chemical properties of dental enamel are less modified. Better understanding of the degradation mechanisms of enamel and dentin would contribute to the development of new preventive and therapeutic methods for patients undergoing radiotherapy.

Summary: This study aimed to investigate the immune response and neutralizing activity against SARS-CoV-2 among primary health care workers (PHCW) in France and assess the association between neutralizing activity and various factors, including the COVID-19 vaccination scheme. The study found that individuals with previous SARS-CoV-2 infection were more likely to have neutralizing antibodies, regardless of vaccination status. Among those vaccinated with two doses, the time since vaccination was associated with the detection of neutralizing antibodies.

Summary: This review analyzed the cytocompatibility of Co-Cr dental alloys. In vitro studies indicated that Co-Cr alloys have good cytocompatibility compared to Ni alloys, while in vivo studies found that Co-Cr rarely causes allergic reactions and irritation, except for individuals allergic to Co or Cr. Further research on titanium-based materials is needed for better results.

Summary: This study investigated the effect of a synthetic amelogenin-derived peptide (ADP-5) on periodontal cell behavior and compared it to a commercial gel Emdogain((R)). The findings showed that ADP-5 enhanced cell proliferation and remineralization, and the ADP-5 experimental hydrogel exhibited similar biological behavior to Emdogain((R)) in terms of cell colonization, mineralization, and inflammatory profile.

Summary: This study evaluated the capability of a 3D fibrous scaffold to transmit mechanical loading to periodontal ligament cells. The results showed that dynamic loading had an impact on cell morphology, with fewer visible cells on the scaffold surface and decreased expression of actin filament. Additionally, dynamic loading tended to decrease Alkaline Phosphatase activity and Interleukin-6 production, while these biomolecular markers increased after static culture for 21 days. These findings suggest that load transmission occurs in the 3D electrospun PCL fibrous scaffolds, providing a valuable tool for studying periodontal mechanobiology.

Summary: In this study, CHX-loaded calcium hydroxide pastes were used as intracanal medications to control infections and inflammation in endo-periodontal lesions. The results showed that the root canal can serve as a reservoir for periodontal drug delivery, and the CHX-based intracanal medication was effective in reducing inflammation and inhibiting the growth of pathogens.
