This study is designed to study the effect of light amplified high intensity LED versus conventional curing on marginal sealing of direct compound posterior bulk-fill resin composite restorations.42 freshly extracted human premolars free from caries and cracks were selected, they were divided into three main equal groups (N=14), according to the light intensity used in curing; (L₁): conventional LED curing (800 mw/cm²), (L₂): light amplified high intensity LED for 5 seconds, (L₃): light amplified high intensity LED 10 seconds. Each main group is divided into 2 subgroups according to aging period (T) where (T1) represents storage for 24 hours, (T₂) represents storage for 3 months in artificial saliva. Standard proximal box cavities were prepared. The dimensions were 2±0.2 mm for the bucco-palatal or bucco-lingual width. The depth was standardized to be 4 mm and it was 1.5mm from the cervical margin to the pulpal floor. Specimens were stored in artificial saliva then they were immersed in 2% methylene blue dye and sectioned with automated diamond saw
