summary The effect of indirect and semi‐direct curing systems of Cl II composite inlays on microleakage was investigated in vitro and compared to conventional direct posterior composite restorations. Nearly identical Cl II cavities were restored with the same composite resin using different polymerization systems. Microleakage assessment was carried out after cyclic loading and thermal stressing by assessing the dye penetration. The data showed that all inlay techniques resulted in improved marginal sealing compared with conventional restorations. However, the indirect procedure resulted in significantly reduced microleakage compared to the semi‐direct inlay techniques.
