This study investigates the green synthesis of silver nanoparticles (AgNPs) using Azadirachta indica extract and their incorporation onto orthodontic brackets, enhanced with different concentrations of Azadirachta indica extract. AgNPs exhibit strong antimicrobial activity, making them promising agents in biomedical applications. The synthesized AgNPs were characterized using UV-Vis spectroscopy, FTIR, XRD, and FESEM. The AgNPs were embedded into orthodontic brackets to assess their antimicrobial properties against Staphylococcus aureus and Escherichia coli. Characterization results confirmed the successful formation of crystalline, spherical AgNPs with sizes ranging from 30–68 nm. Antimicrobial testing revealed clear zones of inhibition around AgNP-coated brackets, demonstrating enhanced antibacterial efficacy. The study supports the potential of eco-friendly synthesized AgNPs for improved oral health in orthodontic treatments.
