“…Materials developed with functionalized glass fibers, which leads to strong interfacial bonding between fibers and the resin matrix, were employed to enhance the mechanical properties of dental composites [ 32 ]. Including materials in the structure of dental composites caused an improvement in strength, resistance to body fluids, and corrosion resistance, while also providing antibacterial properties [ 34 , 38 ].…”

Short glass fibers are generally used in posterior dental restorations to enhance the mechanical properties and improve the material microstructure. Two resin-based composites (S0 and SF) were formulated and characterized to investigate the influence of zirconium in their characteristics and properties. The organic part of the investigated materials was the same (BisGMA, TEGDMA, and a photochemical polymerization system), and in the inorganic part, besides quart, glassA, and hydroxylapatite with Zn, sample S0 contained strontium glass with zirconium and sample SF contained fiber powder of chopped zirconium. The samples were characterized by the degree of conversion (DC), mechanical properties, water sorption (WS), scanning electron microscopy (SEM), atomic force microscopy (AFM) before and after the WS test, and antimicrobial properties. The results obtained were subjected to one-way ANOVA and Tukey’s statistical tests. Both samples had a high DC. Regarding the mechanical properties, both samples were very similar, except DTS, which was higher for the composite without fibers. After 14 days, the WS value of the SF sample was lower than that of the S0 sample. Water caused significant changes in the topography of the SF sample, but thanks to its antimicrobial properties and the diffusion phenomenon, SF had a more pronounced antimicrobial effect. This study shows that the addition of appropriate amounts of Sr-Zr-glass powder gives the material in which it is added similar properties to material containing chopped zirconium glass fiber powder. According to the antimicrobial test results, resin composites containing experimental zirconia fillings can be considered in future in vitro clinical studies for posterior reconstructions with significantly improved mechanical properties.

“…New coating materials can be prepared using different concentrations of SiC-TiO2-graphene and Azadirachta indica (Neem) extract to coat the nanofilms. [38,39] Sustainable production of plant-based nanoparticles is an important research goal in dental implants. Compared to traditional organic antibacterial agents, it is superior in terms of reliability, durability and heat resistance against bacterial pathogens (except Staphylococcus aureus and E. coli) and antifungal activity against C. albicans and Aspergillus niger.…”

Over time, there has been a lot of interest in the synthesis of green AgNPs utilising plant extracts due to the remarkable antibacterial capabilities of these nanoparticles. These particles' nanosized makes it easier for them to pass through cell membranes, interacts with internal organelles, and eventually damages cells when they proliferate. With the exceptional benefits, including practicality, simplicity of usage, and the utilisation of specialised processes like bacteria, plants are currently the preferred method for synthesising metal nanoparticles. Based on the idea of converting silver ions (Ag+) to silver nanoparticles (Ag0), green synthesis techniques for the synthesis of silver nanoparticles are provided. The literature reveals that the modified metal nano particles modifying with green methods are already practicing by dental clinicians, whereas still less percentage of practitioners are using this green nano technology. Hence this narrative review includes different metal nano particles using in dentistry and different green methods using to modify the environmentally friendly dental practices.

“…One of the most common solutions to decrease the corrosion rate is to modify the material surface, a usually simpler and more practical approach than changing the bulk structure and composition [20,21]. Different types of coatings have already been developed for the application of magnesium-alloys, such as β-tricalcium phosphate [22], hydrogenated amorphous silicon [23], nanomembranes obtained by electrospinning [24], electrodeposited hydroxyapatite [25,26], calcium phosphate conversion [27], and magnesium fluoride [28], among others. These coatings can partially control material degradation.…”

MgF2-coated screws made of a Mg-2Y-1Mn-1Zn alloy, called NOVAMag® fixation screws (biotrics bioimplants AG), were tested in vitro for potential applications as biodegradable implants, and showed a controlled corrosion rate compared to non-coated screws. While previous studies regarding coated Mg-alloys have been carried out on flat sample surfaces, the present work focused on functional materials and final biomedical products. The substrates under study had a complex 3D geometry and a nearly cylindrical-shaped shaft. The corrosion rate of the samples was investigated using an electrochemical setup, especially adjusted to evaluate these types of samples, and thus, helped to improve an already patented coating process. A MgF2/MgO coating in the µm-range was characterized for the first time using complementary techniques. The coated screws revealed a smoother surface than the non-coated ones. Although the cross-section analysis revealed some fissures in the coating structure, the electrochemical studies using Hanks’ salt solution demonstrated the effective role of MgF2 in retarding the alloy degradation during the initial stages of corrosion up to 24 h. The values of polarization resistance (Rp) of the coated samples extrapolated from the Nyquist plots were significantly higher than those of the non-coated samples, and impedance increased significantly over time. After 1200 s exposure, the Rp values were 1323 ± 144 Ω.cm2 for the coated samples and 1036 ± 198 Ω.cm2 for the non-coated samples, thus confirming a significant decrease in the degradation rate due to the MgF2 layer. The corrosion rates varied from 0.49 mm/y, at the beginning of the experiment, to 0.26 mm/y after 1200 s, and decreased further to 0.01 mm/y after 24 h. These results demonstrated the effectiveness of the applied MgF2 film in slowing down the corrosion of the bulk material, allowing the magnesium-alloy screws to be competitive as dental and orthopedic solutions for the biodegradable implants market.
