With the continuous application of antibacterial materials, various problems have emerged, such as expensive prices and the potential development of resistance. Cationic antibacterial agents, due to their high solubility, reactivity, and antibacterial properties, are considered as environmentally friendly and cost-effective antibacterial agents. In addition, the electrospinning technique is recognized as a versatile and high-efficiency method to produce nanofibers with multifunctional properties and adjustable structures. In this work, we prepared a series of nanofiber membranes by electrospinning technology using hexadecyl trimethyl ammonium Bromide (CTAB) and 5-Chloro-8-hydroxyquinoline (5-Cl8Q) as antibacterial agents and polylactic acid (PLA) as substrate. The antimicrobial performance of PLA/CTAB/5-Cl8Q was the highest among the prepared materials, which inhabited
S. aureus and
E. coli up to 99.9% and 95.9%, respectively, and the antibacterial properties were stable. In general, PLA/CTAB/5-Cl8Q has great development potential, and it can be applied to real life as a cost-effective, biodegradable and highly antibacterial material.

In this work, a poly(vinylidenefluoride-co-trifluoroethylene) (PVTF) coating on a titanium (Ti) substrate was prepared, and Ti metal surfaces were treated by physical or chemical methods to achieve a high bonding strength with PVTF. Scanning electron microscopy (SEM), atomic force microscope (AFM), and static water contact angles (WCA) were used to characterize the Ti metal surfaces. Further, mechanical stretching testing was employed to measure the bonding strength of PVTF coatings. The possible mechanism for the improved bonding strength could be the higher OH concentrations on Ti metal surfaces, which could lead to the formation of chemical bonds with the F atom of PVTF chains. Finally, a CCK-8 analysis of bone marrow mesenchymal stem cells (BMSCs) cultured on the PVTF coatings confirmed that the physical and chemical treatments had no significant differences in biocompatibility. Such a PVTF coating on a Ti substrate showed the potential of biomedical metal implants.

The purpose of this study was to assess the effects of water storage on the surface microhardness (VHN) and fracture toughness (K
1C) of two self-adhesive restorative materials compared to traditional resin composite and resin-modified glass ionomer cement (RMGIC) restorative materials. Methods: Two self-adhesive materials (Activa and Vertise Flow), a nonflowable composite (Filtek Z250), and an RMGIC (Fuji II) were evaluated. Hardness measurements (
n = 12) were recorded at three time intervals: (i) one-hour post-irradiation; (ii) after one day of storage in water at 37 °C; and (iii) after 90 days of storage in water at 37 °C. Fracture toughness (K
1C) measurements (
n = 12) were conducted after one day of storage in water at 37 °C and 90 days of storage in water at 37 °C. ANOVA and Tukey post hoc tests were used for statistical analysis. Results: Baseline VHN data were 38.2–58.3, decreasing significantly to 28.8–55.6 following 90 days of water storage. The Filtek Z250 had the highest VHN before and after storage, while the Activa had the lowest. K
IC values varied between 0.98–1.32 MPa·m
0.5. The highest value was for the Filtek Z250 while the Fuji II showed the lowest value (after both 1 and 90 days of storage in water). However, K
IC values decreased significantly after storage, except for the Fuji II. Conclusion: Self-adhesive/ion-releasing resin composites were negatively affected by water storage. Material reinforcements are possible future areas to explore.

A Facile Synthesis of P(VDF-TrFE)-Coated-PMMA Janus Membranes for Guided Bone Regeneration

Bone repair and regeneration have aroused widespread interest due to their potential usefulness in cases when bone self-healing is insufficient. In this work, a Poly(vinylidene fluoride-trifluoroethylene)-coated-Poly methyl methacrylate Janus membrane was prepared, where a P(VDF-TrFE) coating on a PMMA film serves as Janus-A to mediate cell growth behavior, owing to its electroactivity, and the PMMA film serves as Janus-B to inhibit soft-tissue growth. A P(VDF-TrFE) coating separated from the substrate was put above the PMMA film before the PMMA film had dried completely, and a Janus membrane formed because of the flowability and adhesion of the nonvolatile PMMA solution. Their bonding could withstand the pressure of the body fluids in the shear direction. Various crystallization substrates were also applied to modulate the P(VDF-TrFE) coating’s surface potentials, as the surface potential would further affect cellular response. It was also found that the responses of the bone marrow mesenchymal stem cells (BMSCs) and bone marrow macrophages (BMDMs) could be adjusted through surface potential modification. Such a Janus membrane could potentially be applied to a biological environment with the effect of both guiding bone regeneration and preventing soft tissue adhesion.

This paper is a review focused on the capability of graphene oxide (GO) coatings in preventing peri-implantitis. Firstly, the paper establishes GO’s place in the frame of carbonic materials and its role as a composite material in dentistry in the prevention of bacterial infections and in sustaining osseointegration. Secondly, the most relevant articles on GO as implant coatings and their associated shortcomings are presented and emphasizing is placed on the areas where more data is needed. The main chapters are devoted to the relationship between GO and biofilm formation on the implants and the surrounding periodontal tissue and we also attempt to evaluate GO’s efficacy in the case of peri-implantitis. Our findings strongly indicate that GO is a promising material for mitigating the problems mentioned, but some answers remain to be answered through rigorous research before declaring it a real success.

Biobased nanomaterials have gained growing interest in recent years for the sustainable development of composite films and coatings, providing new opportunities and high-performance products. In particular, chitin and cellulose nanocrystals offer an attractive combination of properties, including a rod shape, dispersibility, outstanding surface properties, and mechanical and barrier properties, which make these nanomaterials excellent candidates for sustainable reinforcing materials. Until now, most of the research has been focused on cellulose nanomaterials; however, in the last few years, chitin nanocrystals (ChNCs) have gained more interest, especially for biomedical applications. Due to their biological properties, such as high biocompatibility, biodegradability, and antibacterial and antioxidant properties, as well as their superior adhesive properties and promotion of cell proliferation, chitin nanocrystals have emerged as valuable components of composite biomaterials and bioactive materials. This review attempts to provide an overview of the use of chitin nanocrystals for the development of bioactive composite films in biomedical and packaging systems.

Bioactive glasses are promising biomaterials for bone and tissue repair and reconstruction, as they were shown to bond to both hard and soft tissues stimulating cells towards a path of regeneration and self-repair. Unfortunately, due to their relatively poor mechanical properties, such as brittleness, low bending strength and fracture toughness, their applications are limited to non-load-bearing implants. However, bioactive glasses can be successfully applied as coatings on the surface of metallic implants to combine the appropriate mechanical properties of metal alloys to bioactivity and biocompatibility of bioactive glasses. In this review, several available coating techniques to coat metal alloys using bioactive glasses are described, with a special focus on thermal spraying, which nowadays is the most used to deposit coatings on metallic implants.
