Nanotechnology has various applications in restorative dentistry in order to achieve reliable treatment outcomes. The present study aimed to comprehensively review the studies focused on the applications of nano-based materials, technologies, and methods used in restorative dentistry. Related articles were retrieved via searching in databases such as PubMed, Google Scholar, and Scopus. Afterwards, the appropriate references regarding the research subject were assessed, and findings were collected to achieve a comprehensive review study. According to the obtained results, the utilization of nanotechnology in restorative dentistry could yield beneficial outcomes. The dispersion of nano-sized structures in restorative materials could enhance mechanical properties such as diametral and flexural strength and fracture toughness. However, the improvement of the mentioned mechanical properties depends on the type of the nano-sized materials, their content, and type of the additional materials used along with nano-based restorative materials.
