This review discusses the historical development and evolution of resin-based dental composite materials, highlighting their transition from early materials like silicate cements and polymethylmethacrylate (PMMA) to modern composites that are esthetic, strong, and versatile. The article traces the development of these materials, emphasizing key advancements such as the shift from chemical to light-curing systems, improvements in reinforcing particles for better polishing and wear resistance, and the creation of materials with enhanced depth of cure. The evolution of these materials has been driven by the needs of dentists and has led to significant improvements in clinical performance and physical properties. The article also explores future directions, including the development of "bioactive" materials that can interact with the oral environment to promote beneficial effects, such as reducing bacterial biofilms and promoting tooth structure remineralization. Key advancements in polymerization initiators, resin monomers, and fillers have contributed to the development of new composite materials with improved properties. The review also covers recent developments in filler technology, including the use of nanofillers and hybrid composites, as well as the introduction of self-adhesive and bulk-fill composites. The future of dental composite technology is expected to focus on bioactivity, with ongoing research into materials that can actively interact with the oral environment to enhance dental restoration outcomes.This review discusses the historical development and evolution of resin-based dental composite materials, highlighting their transition from early materials like silicate cements and polymethylmethacrylate (PMMA) to modern composites that are esthetic, strong, and versatile.
