The main objective of this study is to offer a rapid and efficient green production of silver nanoparticles with known antibacterial properties. In the current study, a biological approach was applied at room temperature to biosynthesize silver nanoparticles from Chrysanthemum moriflorum flower extract. Aqueous floral extract from Chrysanthemum moriflorum was used to make AgNPs from silver ions fast. This process became apparent when silver nitrate solution was added to the bright yellow flower extract solution, which caused it to turn brown. The biosynthesized AgNPs were examined using transmission electron microscopy (TEM) and ultraviolet-visible (UV-Vis) spectroscopy (TEM). The UV spectra revealed AgNPs' distinctive surface plasmon resonance band at 431 nm. The generated AgNPs, a powerful broad spectrum antibacterial agent, successfully inhibited Escherichia coli and Bacillus sp. To combat the rise in antibiotic resistance, AgNPs made from environmentally acceptable ingredients like flower extract offer a potential weapon

This laboratory study was conducted to demonstrate the effect of the biocide effect of Trichoderma harzianum, silver nanoparticles in the third larval age and the Oryzaephilus full-size beetle, and five concentrations of the biocide T. harzianum (250, 500, 1000, 2000, 4000) ppm and five Concentrations of silver nanoparticles are (1000, 2000, 3000, 5000, 10000, and 20000) ppm. The results showed that the fungicide T. harzianum had the most recent killing rates for all concentrations, as the highest killing rate for the third larval age was 96.7% at 4000 ppm during 72 hours of treatment, while the lowest killing rate for the third larval age was 16.7% at the concentration 250 ppm during 24 hours of treatment. As for the camels, the highest killing rate with the fungicide was 86.7% at the concentration of 4000 ppm during 168 hours of treatment, while the lowest killing percentage for the adult beetle was 0% at the concentration of 250 ppm within 24 hours of the treatment, as for the effect of particles Silver nanoparticles were the highest killing percentage for the third larval age 100.0% at the concentration of 5000 ppm within 72 hours of the treatment, while the lowest killing percentage for the third larval age was 13.3% at the concentration of 1000 ppm within 24 hours of the treatment. As for the adult beetle have reached the highest rate of killing 88.7% when concentrating 20000 ppm within 72 hours of treatment and concentrating 500 and 1000 ppm during 144 hours of treatment. The lowest killing rate of the adult beetle was 16.7% when concentrating 5000 ppm during 24 hours of treatment

Nanotechnology over past decades, has emerged as a mainstay in various fields and has
been employed in various biomedical applications. It is currently being extensively used in
the manufacture of drugs, as a diagnostic aid, in implants, as a prosthetic material and in
tissue engineering. With the recent introduction of advanced Nano robotic models in local
anesthetic procedures, the applications and importance of nanotechnology in the field of
healthcare have gained renewed impetus. This review primarily throws light on the
current applications of silver nanoparticles in the field of Dentistry, emphasizing on
orthodontics in particular, with regard to their antimicrobial properties, anti-cariogenic
effects, Nano silver coating applications of orthodontic brackets, micro implants,
biocompatibility analysis and fixed orthodontic appliances.
