Introduction/Context/Diagnosis
Abstract: Objectives: The present review study aimed to provide a brief history of resin-based composites (RBC) as direct restorative materials and their evolution from macrofill to nanohybrid RBCs, as well as newly developed RBCs with bioactive, antimicrobial, and remineralizing properties. Methods: PubMed, Medline, Google Scholar, and Scopus were searched using the appropriate keywords. Case reports and non-peer-reviewed articles were excluded. Results: Among the 80 papers initially resulting from the literature search, 35 studies were reviewed and included. The application of resin composite as a direct restorative material has increased significantly due to its higher esthetics compared to amalgam and fewer biocompatibility concerns. To improve RBC properties, new resin monomers such as TCD-urethane-based monomers, silorane-based monomers, and Ormocers have been developed and introduced. Additionally, the size, shape, and volume of filler particles have been modified to enhance RBC properties. These advances have resulted in new resin composite materials, including bioactive RBCs with remineralizing potential, smart RBCs with the ability to release ions in decreased pH, antimicrobial RBCs with various filler particles such as newly green silver nanoparticles, nano Cerium Oxide, and silver/Zinc Oxide (Ag/ZnO) nanoparticles, and self-adhesive RBCs. Conclusions: RBCs have evolved significantly since their invention in the 1900s. Newly developed RBCs have compelling physical and mechanical properties in in vitro settings. However, further studies are needed to evaluate their safety and longevity in the oral conditions. Acknowledgment: We would like to express our deepest appreciation to our mentor, Dr. Ganesh, whose invaluable guidance, unwavering support, and insightful critiques have been pivotal in the success of this research.
