The field of dental composites encompasses a diverse array of materials utilized extensively in modern dentistry for both restorative and cosmetic procedures. These composites typically consist of an organic matrix, dispersed filler particles, and a coupling agent to integrate the two. One of the most significant advancements in composite resin development came in the late 1950s when Bowen's successfully formulated a compromise between epoxy and methacrylate resins. Nanoparticles have gained significant attention in dentistry due to their unique properties, including small particle size, increased surface area, and enhanced mechanical and optical characteristics. Various nanomaterials, including nanorods, nanospheres, nanotubes, nanofibers, and dendritic structures, are being explored for their potential in dental composites. These materials offer advantages such as antibacterial properties, remineralization capabilities, and enhanced mechanical strength. Several techniques, including wet precipitation, sol-gel, multiple emulsion, biomimetic deposition, hydrothermal, and electrodeposition, are employed in the synthesis and processing of nanocomposites. Each method offers unique advantages in terms of scalability, cost-effectiveness, and control over material properties. In conclusion, nanoparticles in composites hold tremendous promise in revolutionizing dental restorative materials. By leveraging nanotechnology, researchers can develop materials with tailored properties to meet specific dental needs, ultimately improving patient outcomes and oral health. Ongoing research into antimicrobial mechanisms and fabrication techniques will further advance the field of dental nanocomposites.
