Abstract

The function regarding flowable resin-based composites in restorative dentistry has considerably changed as they have been first introduced as low-viscosity alternatives in late 1990s. Because of the degraded mechanical properties and lower filler content, they were first just suitable for low-stress applications, like cavity liners. However, further advancements in the material science have produced highly-filled, next-generation flowables. The traditional trade-off between durability and fluidity is being challenged by materials’ improved properties, which include higher flexural strength and wear resistance. Furthermore, the development regarding bulk-fill flowables, which use advanced photoinitiators as well as polymerization modulators for the purpose of enabling uniform curing up to 5 mm and deep, single-increment placement, is a significant breakthrough. Through streamlining clinical processes and drastically lowering polymerization shrinkage stress, the method speeds up and enhances the restorations’ effectiveness. This change has allowed flowables to be used in high-stress-bearing posterior restorations and as the main material in difficult aesthetic instances, thereby extending their clinical utility beyond their original focus. Even if a critical review shows differences between the in vivo and the in vitro results, the majority of people agree that modern flowable composites are robust and versatile class of materials. A thorough grasp regarding their unique properties is crucial for the best possible clinical outcome, also their broad use is motivated by the rising desire for minimally invasive and aesthetic treatments.
