Bulk-fill resin composites have received reputation in the current years thanks to their extended depth of cure. This is the end result of incorporating large filler particles, decreasing the quantity of pigments, and altering the monomer structures of the composites. These bulkfill resin composites can be utilized and cured in thicker layers than traditional resin composites. Nevertheless, polymerization shrinkage stress, caused through the activation of the methacrylate-based monomers, can also purpose post-operative sensitivity and marginalleakage, growing the threat for secondary caries. Restorations are now not solely subjected to occlusal put on however most multisurface posterior restorations will additionally exhibit proximal wear. To decrease occlusal put on of a flowable bulkfill composite, an occlusal layer of a traditional kind of restorative composite is applied. However, interproximal the flowable will come at the floor and in approximal contact. Approximal put on of enamel and restorative substances will take place as an end result of the mesial drift. A hastily sporting approximal contact will trade the role of the teeth and the structure of the approximal contour. This is a scientific problem, which is challenging to predict or simulate, however the excessive put on charge of bulk-fill composites is now not in want ofthis phenomenon.
