MICROLEAKAGE STUDIES COMPARING A ONE-VISIT INDIRECT COMPOSITE INLAY SYSTEM AND A DIRECT COMPOSITE RESTORATIVE TECHNIQUE

Problems related to leakage have been observed with direct-filled composite restorations. The development of indirect system of fabrication followed by cementation should theoretically reduce this phenomenon. The present study compares the leakage around directly placed composites with composite inlays prepared by a surgery-based system. The results indicate that the amount of leakage is reduced with the inlay system, but that it is not eliminated.
