Composite resins, which are produced as an alternative to dental amalgam and have been used as filling materials for many years, have an indisputable superiority with their improved physical properties through changes in their formulations, adhesion to tooth hard tissues, high aesthetic appearances with a wide range of colors, mercury-free, having low thermal conductivity, allowing conservative cavity preparation, supporting the remaining tooth tissues after caries removal, completing the restoration in a single session, and being more economical compared to porcelain and gold restorations. In addition to all these advantages, these materials also have some negative properties such as requiring technical precision in their applications, high coefficient of thermal expansion, low modulus of elasticity, exhibiting polymerization shrinkage, low resistance to wear in areas with intense stresses, and the possibility of residual monomer remaining. In recent years, manufacturers have made various modifications to overcome these negative properties of composite resins. Some modifications made for this purpose include changing the organic matrix content in composite resin materials, adding nanoparticles and bioactive materials, improving adhesion properties, changing polymerization systems, and producing "smart materials" as a result of developments in biomimetic dentistry and tissue engineering. The purpose of this review is to strengthen the existing literature on composite materials and summarize the latest developments.
