GASGA TAPIA, Verónica et al. Uses of silver nanoparticles (AgNPs) in dentistry. Mundo nano [online]. 2024, vol.17, n.33, e69816.  Epub Nov 26, 2024. ISSN 2448-5691.  https://doi.org/10.22201/ceiich.24485691e.2024.33.69816.

AgNPs are being widely used due to their excellent antimicrobial properties that allow them to be incorporated in various areas of dentistry ranging from dental materials, orthodontics, endodontics, periodontics and prosthodontics among others. The objective of this work was to review the use of AgNPs in different areas of dentistry and the associated technological innovations. Systematic searches were performed in the EBSCOhost and PubMed databases, with the keywords: “AgNPs” or “silver nanoparticles”, “dentistry” or “dentist” or “dental”, and “materials” in a period from 2012 to 2023 in the English language. A total of 261 articles were found, repeated articles, review articles, and articles that did not belong to the dental area were eliminated. A total of 116 articles that met the criteria were included in the review, it can be observed that most of the research is in vitro studies and a small part is clinical research or conducted on animals, most of the research show positive and innovative results for the use of AgNPs. The studies show an optimal antibacterial activity of AgNPs when they are combined with dental materials such as rinses, irrigant solutions, cements, resins, adhesives, metal coatings, antiseptic solutions, surgical dressings, among others. The literature reviewed shows a promising future for AgNPs since they not only have antibacterial activity against the main aerobic and anaerobic Gram positive and Gram-negative oral bacteria but also antifungal effect and anti-inflammatory properties, without compromising the properties of most of the materials in which they are incorporated. However, their use remains controversial because these nanomaterials belong to a new class of material; progress in this new discipline (nanotoxicology) depends on finding methodologies that allow the evaluation of toxicity in chemical states, in vitro and clinical studies.

Keywords : silver nanoparticles; AgNPs; odontology.
