Abstract :Bulk fill resin composites (BFRCs) were developed to simplify restorative procedures and overcome the limitations of the incremental approach. Applicable in thicknesses of 4–5 mm, they reduce working time while providing satisfactory mechanical and clinical performance. This review article synthesizes in vivo evidence from the last decade on posterior teeth, focusing on the retention, marginal adaptation, marginal discoloration, postoperative sensitivity, and secondary caries of BFRC restorations. The findings indicate that BFRCs exhibit comparable annual failure rates and retention to composite resins placed incrementally. While marginal discoloration increased over time, no significant differences in marginal integrity were identified. Flowable BFRCs provided superior cavity adaptation, whereas high-viscosity variants offered enhanced mechanical strength. Advancements such as sonic activation and thermo-viscous systems have contributed to improved viscosity and cavity adaptation. Overall, BFRCs represent a clinically reliable material, offering efficiency and acceptable longevity in restorative dentistry.
