“…AgNPs have the same efficacy as sodium hypochlorite as a canal irrigant to minimize microleakage in the root canal system [ 39 , 40 , 51 ]. Denture stomatitis is less likely to occur when these materials are used with acrylic resins because of their antifungal properties [ 61 , 77 ]. Osteogenic differentiation potential has the ability to produce an antibiocidal surface layer on top of titanium implants, which would help avoid peri-implantitis [ 41 ].…”

Silver Nanoparticles in Dental Applications: A Descriptive Review

Silver nanoparticles have been a recent focus of many researchers in dentistry, and their potential uses and benefits have drawn attention in dentistry and medicine. The fabrication and utilization of nanoscale substances and structures are at the core of the rapidly developing areas of nanotechnology. They are often used in the dental industry because they prevent bacteria from making nanoparticles, oxides, and biofilms. They also stop the metabolism of bacteria. Silver nanoparticles (AgNPs) are a type of zero-dimensional material with different shapes. Dentistry has to keep up with changing patient needs and new technology. Silver nanoparticles (AgNPs) can be used in dentistry for disinfection and preventing infections in the oral cavity. One of the most interesting metallic nanoparticles used in biomedical applications is silver nanoparticles (AgNPs). The dental field has found promising uses for silver nanoparticles (AgNPs) in the elimination of plaque and tartar, as well as the elimination of bacterial and fungal infections in the mouth. The incorporation of AgNPs into dental materials has been shown to significantly enhance patients’ oral health, leading to their widespread use. This review focuses on AgNP synthesis, chemical properties, biocompatibility, uses in various dental fields, and biomaterials used in dentistry. With an emphasis on aspects related to the inclusion of silver nanoparticles, this descriptive review paper also intends to address the recent developments of AgNPs in dentistry.

“…Both groups showed similar inflammation. Thus, adding 1% AgNPs to MTA did not affect animal inflammation [ 77 ]. The combination of calcium hydroxide [CaOH] and AgNPs was found to be more effective against E. faecalis in root canal therapy than either were alone.…”

Polymethyl methacrylate (PMMA), widely used in orthodontics and dentures, exhibits suboptimal mechanical properties, including flexural strength (FS), impact strength (IS), and tensile strength (TS), which are critical for ensuring durability, resistance to fracture, and overall functionality of dental appliances. Silver nanoparticles (AgNPs) are a promising filler due to their antimicrobial properties. This pre-registered (osf.io/yqftx) PRISMA-compliant meta-analysis compared the mechanical properties of PMMA/AgNP composites to pure PMMA, considering mean particle size and concentration. Of 360 records from ACM, BASE, PubMed, and Scopus, 35 studies were included (κ = 0.91), covering 88, 38, and 11 tests on FS, IS, and TS, respectively. FS increased only between 30–70 nm (r = 0.00; ρ = 0.03; R2deg2 = 0.13). IS remained higher for <80 nm and increased between 15 and 25 nm (r = −0.41; ρ = −0.28; R2deg2 = 0.59). TS favored 55 nm but had limited data (r = −0.24; ρ = 0.63; R2deg2 = 0.99). FS decreased with increasing wt%, showing no discernible trend (r = −0.22; ρ = −0.34). IS increased within 0.0–4.0 wt%, particularly 0.5–2.0 wt% (r = −0.15; ρ = −0.35; R2deg2 = 0.54). TS peaked at 0.5–2.0 wt% (r = −0.20; ρ = −0.24; R2deg2 = 0.91). Optimal mechanical properties of PMMA/AgNP likely fall within 15–70 nm mean nanoparticle size and 0.5–4.0 wt% concentration.

Background/aim Acrylic resin denture base material with all its varieties and curing techniques enormously influence their physical, biological, and mechanical properties. This study designed to evaluate and compare the impact of acrylic resin reinforcement with titanium oxide nanoparticles (TiO2NP) on physical, biological, and mechanical criteria of two dissimilar denture base materials. Materials and methods This study was constructed on 120 specimens of 2 different types of acrylic resin denture base materials. The specimens were divided equally into 2 groups (60 each), group I (heat cured acrylic resin) and group II (microwave cured acrylic resin). Each group was additionally divided into two subgroups (each 30). Subgroup A as control, while subgroup B was modified with 3% TiO2NP. Biological evaluation was performed on Enterococcus faecalis by using antimicrobial assay by agar diffusion test color stability via employing spectrophotometer, and the Modulus of elasticity through universal testing machine. Results Regarding the results of biological assessment, groups IA and IIA (control groups) revealed no inhibitory zone, while groups modified with 3% TiO2NP group IIB demonstrated significantly higher (P < 0.05) inhibitory zone when compared with group IB. Concerning color stability, Regarding color stability, Group IA and IIA (control groups) demonstrated the highest color changes, while Group IB and IIB(modified groups) demonstrated the lowest color changes. In modulus of elasticity, groups IB and IIB were significantly higher (P<0.05) than groups IIA and IIB. Conclusion Adding 3% TiO2NP to heat and microwave cured resins induced antibacterial characteristics against E. faecalis. Besides improvement of the evaluated mechanical (modulus of elasticity) and color stability properties.
