Abstract Periodontitis, one of the most prevalent dental diseases, causes loss bone and gum tissue that hold teeth in place. Several bacteria, commonly present clinically healthy oral cavities, may induce perpetuate periodontitis when their concentration rises gingival sulcus. Antibacterial effect against various Gram-negative Gram-positive including pathogenic drug-resistant ones, has been shown for several distinct transient metal oxide NPs. Therefore, NPs be used biomedicine to treat periodontal problems nanotechnology inhibit development microorganisms. Instead using harmful chemicals or energy-intensive machinery, biosynthesis nanoparticles (NPs) suggested. To produce NPs, ideal technique is “Green” synthesis because its low toxicity safety human health environment. Gold (AuNPs) appear less toxic mammalian cells than other nanometals antibacterial activity not dependent on reactive oxygen species (ROS). AgNPs also possess chemical stability, catalytic activity, superior electrical thermal conductivity, name a few advantageous characteristics. It was observed zinc (ZnO) copper (Cu) exhibited discernible inhibitory effects gram-positive gram-negative bacterial strains, respectively. ZnO demonstrated bactericidal microorganisms responsible periodontitis. Medications containing magnetic are highly effective multidrug-resistant fungal infections.
