Brief summary

Posterior resin composite is challenging esthetic restoration. Patients seek for durable, esthetic and functional restorations in molars. one of the major problems is polymerization shrinkage. Some materials were developed to overcome the polymerization shrinkage, among them bulk fill resin composite which have been developed to reduce the shrinkage stress during polymerization and offer much greater depth of cure. This is achieved by the addition of fillers such as barium aluminum silicate filler, ytterbium trifluoride and mixed oxides. Furthermore, a prepolymerized fillers have been added with silanes to reduce shrinkage stress. so, the objective of this trial is to clinical Evaluate and compare clinical performance of bulk fill VS incremental filling technique.
