A comprehensive overview of Bulk Fill Composites (BFCs) in dentistry, detailing their evolution, properties, and clinical applications, particularly for posterior restorations. The text covers the chemical composition and mechanical characteristics of BFCs, highlighting the ongoing challenge of polymerization shrinkage and the various methods developed to mitigate it, such as dual-curing and fiber reinforcement. Significant attention is given to the importance of proper adhesion and the role of light curing units (LCUs), including the physics of light and the necessity of sufficient radiant energy for optimal material conversion. Furthermore, the sources discuss the clinical performance and longevity of BFCs, comparing them to conventional composites and exploring advancements in self-adhesive and bioactive materials to improve outcomes and reduce technique sensitivity.
