“…Other GCs to mention are the precipitations of apatite and phlogopite in Na 2 O -MgO -CaO -Al 2 O 3 -SiO 2 -P 2 O 5 -F glass and the precipitations of apatite and wollastonite in Na 2 O -K 2 O -MgO -CaO -SiO 2 -P 2 O 5 -CaF 2 glass, which is known as Bioverit and Implants, respectively. Table 2 shows the most ceramic glass and BG as a material in dentistry [116]. The function of a material without damaging the surrounded tissues determines whether it's suitable for dental applications.…”

Bioactive glass (BG) and glass-ceramics (GC) have been employed for bone treatment tissue engineering applications. Bioactive glasses/bioglasses can be considered promising materials for bone-regenerative scaffolds fabrication, owing to the adaptable properties that make them appropriately be designed regarding their composition. The essential properties of bioactive glasses, enabling them to be applied in the engineering of bone tissue, can be explained as their potential to augment differentiation osteoprogenitor and cells of mesenchymal stem cells, enzyme activity, osteoblast adhesion, and revascularization. Much research is conducted for the development of phosphate glasses, borate/borosilicate BGs, and silicate. Accordingly, some metal-based glasses have also been surveyed for tissue engineering uses, technologically and biomedically. Many rare elements can also be incorporated in the network of the glass to achieve promising properties, possessing a positive influence on the associated angiogenesis and/or remodeling of bone. This review motivates for providing an overview toward bioactive glasses' general requirements, composition, production, and impact of ion substitution on bioactive glass. Attention has also been given to developments of bioactive glass applications in bone grafting, bone regeneration, drug delivery, dental implant coatings, antibacterial agents, and soft tissue engineering as well as challenges and future perspectives.

“…The goal of any dental restoration is to create a natural appearance that is highly aesthetic while remaining functional [ 1 ]. Among all available current dental restorative materials, resin composites have been widely used for anterior restorations because of their exceptional aesthetics and durability [ 2 , 3 , 4 , 5 ]. Since natural teeth consist of different layers (i.e., enamel, dentine and pulp), dental restorations must also replicate this pattern in order to achieve an optimal result, and this is normally achieved through layering techniques of different materials [ 6 ].…”

Usually, dentin and enamel shades are layered in dental restorations with the purpose of mimicking the natural appearance of teeth. The main objective of this study was to develop and assess accuracy of a color-prediction method for both monolithic and layered dental resin-based composites with varying shades and under different illuminants. A total of 15 different shades of VITAPAN Excell, VITAPAN Dentine and VITA Physiodens as well as VITA Enamel of five different thicknesses (0.5–2.5 mm range) were used to manufacture monolithic and layered samples. A non-contact spectroradiometer with CIE 45∘/0∘ geometry was used to measure the color of all samples over a standard ceramic black background. Second-degree polynomial regression was used as predictive method for CIE-L*a*b* color coordinates. Performance of predictive models was tested using the CIEDE2000 total color difference formula (ΔE00), while accuracy was evaluated by comparative assessment of ΔE00 with corresponding 50:50% acceptability (AT00) and perceptibly (PT00) thresholds for dentistry. A mean color difference between measured (real) and predicted color of ΔE00=1.71, with 62.86% of the color differences below AT00 and 28.57% below PT00, was registered for monolithic samples. For bi-layered samples, the mean color difference was roughly ΔE00=0.50, with generally 100% and more than 85% of the estimations below AT00 and PT00, respectively. The predictive method allowed highly accurate color estimations for both monolithic and layered dental resin-based composites with varying thicknesses and under different illuminations. These results could be useful to maximize the clinical success of dental restorations.

“…Composites are used to cover the dental filling to protect it from falling out or to hide the shape of the distorted tooth or protect a weak tooth from breaking. The most materials are not permanent and many and the materials requirements used in dental are biocompatible, permanent bonding with tissue or bone, suitable appearance, shows efficiency function, and ability of repair or regeneration of missing or damaged tissues [8]. The humans tooth bone structure is composed of Enamel, Dentin, and Dental pulp the first protective layer of the humans tooth is Enamel it is made up of 96 percent calcium apatite, which comes in two forms: hydroxyapatite (HAP) [Ca10 (PO4)6(OH)2] and Fluor apatite [Ca10(PO4)6F2] Crown contains 68% of collagen consist of a layer of dentin which covers the pulp that represents the inner layer of the tooth and the cementum layer it's the outer layer of the tooth root and its surrounds the dentin pulp, so the dental composites have to simulate the natural teeth mechanical properties such as hardness, compression and roughness thus we used nanotechnology to improve the dental.…”

The current work focuses on the preparation of magnesium oxide nanoparticles using aqueous magnesium chloride salts and sodium hydroxide powder by a simple chemical precipitation method and at an annealing temperature of 700 °C for 6 hours. The structural and morphological properties of the magnesium oxide nanoparticles were investigated using X-ray diffraction (XRD). Polycrystalline cube and using the Scherer equation showed a crystalline size of 17.23 nm. EDS analyzes showed high purity. Scanning electron microscopy (FESEM) showed the spherical shape of the magnesium oxide particles. With particle size within the range (65-185) nm. While a (PMMA)-HAP nanocomposite was synthesized. -MgO) for use in dental applications such as fillings and dentures. A nanocomposite (PMMA-HAP-MgO) was manufactured by manual molding method by strengthening the poly methyl methacrylate polymer with certain weight ratios(1%,5%,and 10%) from a mixture of nano powder where the added ratios were (99%PMMA-1%HAP,95%PMMA-7.4%HAP-0.3%MgO,and 90%PMMA-9.4%HAP-0.3%MgO). The topographical properties (surface roughness) of the nanocomposite samples were studied by testing them with an atomic force microscope. The results showed an increase in the value of pure PMMA, where the use of nanoparticle filler by 5% (4.7% HAP -0.3% MgO) affected both the roughness and the root mean square ratio of the distribution of nanoparticles on the surface of the composite and the shape of the particles led to a roughness more than the polymer pure. The antibacterial activity of the polymeric overlay was examined on the bacteria that cause dental caries for (Streptococcus mutans), where the zone of inhibition were (1 mm, 2 mm, 5 mm) for the nanocomposite and no activity for pure PMMA.
