This review presents a comprehensive examination of resin-based dental composite materials, tracing their evolution from early silicates to contemporary resin composites and alkasites. The development of Bis-GMA composites by Bowen in 1962 marked a significant milestone, introducing a durable, cross-linked matrix that addressed wear resistance and polymerization shrinkage issues. The advancement of fillers, particularly nano-fillers and multimodal filler structures, has been crucial in enhancing the mechanical, physical, and aesthetic properties of resin composites, contributing to wear resistance and low polymerization shrinkage. Contemporary resin composites incorporate inorganic fillers with optimized size and distribution to reduce light scattering, improve polymerization depth, and meet aesthetic standards by matching natural tooth translucency. The addition of fiber structures and novel filler types, such as nanotubes and bioactive glass, has further strengthened composites' mechanical properties and antibacterial efficacy, addressing secondary caries. Despite advancements, challenges persist with biodegradation, optical stability, and bacterial biofilm accumulation, highlighting the need for antimicrobial agents within resin matrices. Emerging antibacterial technologies, including silver nanoparticles, zinc oxide, and chitosan, have shown the potential in enhancing biointeractivity while maintaining mechanical integrity. This review underscores the importance of innovative filler technologies and bioactive agents in advancing the performance and clinical longevity of resin-based dental materials.
