Microbial colonization on material surfaces is ubiquitous. Biofilms derived from surface-colonized microbes pose serious problems to the society from both an economical perspective and a health concern. Incorporation of antimicrobial nanocompounds within or on the surface of materials, or by coatings, to prevent microbial adhesion or kill the microorganisms after their attachment to biofilms, represents an important strategy in an increasingly challenging field. Over the last decade, many studies have been devoted to preparing meta-based nanomaterials that possess antibacterial, antiviral, and antifungal activities to combat pathogen-related diseases. Herein, an overview on the state-of-the-art antimicrobial nanosized metal-based compounds is provided, including metal and metal oxide nanoparticles as well as transition metal nanosheets. The antimicrobial mechanism of these nanostructures and their biomedical applications such as catheters, implants, medical delivery systems, tissue engineering, and dentistry are discussed. Their properties as well as potential caveats such as cytotoxicity, diminishing efficacy, and induction of antimicrobial resistance of materials incorporating these nanostructures are reviewed to provide a backdrop for future research.

“…Composite resins containing 1% silver nanoparticles (AgNPs) or zinc oxide nanoparticles (ZnO NPs) exhibited a better antibacterial activity. Note that the antibacterial effect of composite resin containing ZnO NPs on Streptococcus mutans ( S. mutans ) was significantly higher than that containing AgNPs [1,18,19]. Additionally, S. mutans activity could be significantly inhibited by AgNPs which was formed in situ via a photoreduction mechanism concomitant to the polymerization reaction [3].…”

“…The toxicity of NPs may be influenced by many factors. Some studies did not explore the toxicity of NPs [18,45,64,67,124], while others showed that NPs with antibacterial properties did not exhibit cytotoxicity within a certain concentration ranges [11,57,80,92,94,101,115,120,146,154,164]. Not surprisingly, low concentration NPs with antibacterial properties were non-toxic while the high-concentration ones exhibited more pronounced cytotoxicity [110], and even some researchers found that the toxicity of NPs exhibited a dose-dependent effect [6,9,159].…”

Oral cavity incessantly encounters a plethora of microorganisms. Plaque biofilm—a major cause of caries, periodontitis and other dental diseases—is a complex community of bacteria or fungi that causes infection by protecting pathogenic microorganisms from external drug agents and escaping the host defense mechanisms. Antimicrobial nanoparticles are promising because of several advantages such as ultra-small sizes, large surface-area-to-mass ratio and special physical and chemical properties. To better summarize explorations of antimicrobial nanoparticles and provide directions for future studies, we present the following critical review. The keywords “nanoparticle,” “anti-infective or antibacterial or antimicrobial” and “dentistry” were retrieved from Pubmed, Scopus, Embase and Web of Science databases in the last five years. A total of 172 articles met the requirements were included and discussed in this review. The results show that superior antibacterial properties of nanoparticle biomaterials bring broad prospects in the oral field. This review presents the development, applications and underneath mechanisms of antibacterial nanoparticles in dentistry including restorative dentistry, endodontics, implantology, orthodontics, dental prostheses and periodontal field.

“…Another article described the use of zinc oxide nanoparticles as an additive to interim cement for antibacterial properties. 249 Temp Bond NE was modified by incorporation of the zinc nanoparticles, resulting in significant S. mutans growth inhibition at only 0.25% volume fraction while not compromising diametral tensile strength. Metal nanoparticles continue to be a promising antimicrobial for restorative materials of all types, but much needs to be done to evaluate factors such as duration of effect and the development of microbial resistance over time.…”
